Frequency of maxillofacial injuries in all-terrain vehicle collisions.

PURPOSE: We sought to evaluate the frequency and distribution of maxillofacial injuries associated with all-terrain vehicle (ATV) collisions and to compare this with patients involved in motorcycle accidents over the same 5-year period at the University of Alabama at Birmingham.Patients and methods The records of all patients involved in ATV collisions who were admitted to the University of Alabama at Birmingham Trauma Center from January 1998 to January 2003 were reviewed. Age, gender, mechanism of injury, length of stay, Glasgow Coma Scale (GCS) score, maxillofacial injuries, Injury Severity Score (ISS), and maxillofacial Abbreviated Injury Scale (AIS) score were the factors considered for the study. These variables were also analyzed for patients involved in motorcycle collisions who sustained maxillofacial trauma. RESULTS: There were a total of 72 ATV collisions; 23 patients (32%) sustained maxillofacial injuries. The mean age was 31, and there were 59 males (82%) and 13 females (18%). The most common mechanism of injury was an ATV rollover. The warmer seasons and weekend days had the highest frequency of ATV trauma. Of the 23 patients who sustained maxillofacial injuries, the average maxillofacial AIS score was 2. The length of stay and GCS score were 8 days and 12, respectively, compared to 5 days and 15 in the nonmaxillofacial injury group. The most common maxillofacial fracture seen was a zygomaticomaxillary complex fracture (n = 8), followed by mandibular fractures (n = 6), and orbital floor blowout fractures (n = 5). Eighty-three percent of patients with maxillofacial injuries required an operative intervention during their hospitalization. The distribution of maxillofacial fractures in the ATV group was similar to that of an equivalent motorcycle group, but the frequency for the ATV group was higher (32% versus 8%). The length of stay for the motorcycle group was 11 days versus 8 days for the ATV group. The GCS scores, maxillofacial AIS scores, and ISS were similar between the 2 groups (12, 2, and 18, respectively). In patients who sustained maxillofacial fractures, neurologic injuries were the most frequent concomitant injury in the ATV group, whereas orthopedic injuries occurred more often in the motorcycle group. CONCLUSIONS: Maxillofacial injuries are common findings in ATV collisions. ATV patients with maxillofacial fractures have more neurologic impairment at admission and longer hospitalizations than patients sustaining motorcycle injuries. There needs to be an increase in the public health effort to educate individuals about the dangers of ATVs and to provide proper safety guidelines before the purchase of a vehicle.     

A review of 100 closed head injuries associated with facial fractures.

One hundred closed head injuries associated with facial fractures treated over a 78-month period at a level I trauma center in Northeast Ohio were reviewed. The incidence of closed head injury in patients with facial fractures was 17.5%. Males suffered closed head injuries four times more often than females, and sustained severe intracranial injuries eight times as often. The 16- to 30-year age group predominated (59%). Although motor vehicle accidents were the most frequent cause of injury (61%), motorcycle accidents were associated with the most severe head injury. The mandible/midface fracture ratio (1.3:1) was almost half that of the non-head-injured population (2.1:1). Facial fracture complications were found to have a similar incidence (14%) as in the non-head-injured population, but were associated with more severe intracranial injuries.     

Correlating facial fractures and cranial injuries.

PURPOSE: This study retrospectively evaluated individuals with traumatic injuries from different mechanisms and tried to determine if there is any relationship between various isolated or combined fractures of facial skeleton and cranial injuries. MATERIALS AND METHODS: We retrospectively studied hospital charts of all patients who reported to the trauma center at Kasturba Hospital in Manipal with facial fractures and suspected cranial injuries during a 5-year period (January 1, 1995 to December 31, 1999). These patients were admitted to the Department of Neurosurgery or the Maxillofacial Unit of Kasturba Hospital, Manipal. The complete medical record of each patient was reviewed, recording the following in a standard format: age, gender, cause of injury, type of facial fractures, type of cranial bone fracture, concussion, intracranial injury, cerebrospinal fluid (CSF) rhinorrhea, CSF otorrhea, and the Glasgow coma scale. RESULTS: The study data were collected as part of retrospective analysis. A total of 12,329 patients reported to the trauma center of the study hospital during a 5-year period with various injuries. A total of 772 patients had facial fractures (6%). A total of 108 patients with a combination of cranial injuries and facial fractures were identified within this group (14%). Gender predilection was seen to favor males (90%) more than females (10%). The ratio was seen to be nearly 9:1. The ages of the patients ranged from 7 to 70 years with mean age being 32 years (standard deviation [SD] = +/-12). Central midfacial bone involvement was found to be more commonly associated with head injury. CONCLUSIONS: There is a correlation between midfacial injuries and CNS trauma. A more exhaustive multicentric case-control study with a larger sample and additional parameters will be essential to reach definite conclusions regarding the spectrum of head injuries associated with facial fractures.     

Application of a facial injury severity scale in craniomaxillofacial trauma.

PURPOSE: To establish a Facial Injury Severity Scale (FISS) that correlates with patient outcome and provides a practical tool for communication between clinicians and healthcare personnel for management of facial trauma. PATIENTS AND METHODS: All patients presenting to the Emergency Department (ED) at Legacy Emanuel Hospital (Level One Trauma Center) in Portland, Oregon between 01/1993 and 6/2003 with facial fractures with or without concomitant non-facial injuries where identified retrospectively. The diagnosis and treatment of all facial fractures were conducted by the Oral and Maxillofacial Surgery (OMFS) service. The following data were collected; age, gender, mechanism of injury, detailed diagnosis of facial fractures, disposition, and the length of hospital stay (LOS). The hospital operating room charges (ORC) for the treatment of each patient's facial fractures were also obtained. We designed the FISS to be a numeric value composed of the sum of the individual fractures and fracture patterns in a patient. Not all fractures of the face are weighted equally in the FISS because not all fracture patterns are equal in severity. Individual fracture points within the scale were optimized to result in the highest correlation. RESULTS: A total of 1,115 patient admissions to the ED with blunt or penetrating maxillofacial injuries were identified and reviewed. Full information on operating room charges (ORC) was available for 247 patients (average age: 32, SD +/- 17; range, 2 to 84; male:female, 3:1; blunt:penetrating, 232:15). The FISS scores were calculated for each patient (average FISS: 4.4, SD +/- 2.7; range, 1 to 13). Hospital ORC for the treatment of each patient's maxillofacial injuries were obtained from the hospital financial services (average ORC: 4,135 dollars, SD +/- 2,832 dollars; range, 845 dollars to 18,974 dollars). A significant correlation was identified between the FISS and the ORC (R value = .82). The length of stay was significantly associated with the FISS (t = 4.7, 245 degrees of freedom, P = .000004). Although the association was statistically significant, FISS is not a very good predictor of length of stay. The correlation between the predicted and observed values was 0.38. There were 3 deaths among the 247 entries. Those 3 deaths had higher than average FISS scores, but the difference between the scores of survivors and non-survivors was not significant (P = .08). The number of deaths was small and a larger study would be required to resolve this question. CONCLUSIONS: We introduce a FISS that is easily calculated and reliably predicts the severity of maxillofacial injuries as measured by the operating room charges required to treat the facial injury. The scale is also an indicator of hospital length of stay. We anticipate this to be a valuable tool for assessment and management of maxillofacial trauma.     

A 3-year survey of assault-related maxillofacial fractures in central Switzerland.

AIM: The aim of this study was to analyse the character of assault-related facial fractures in central Switzerland and to compare their prevalence with the data presented in similar reports from other countries. MATERIAL: The present study comprised 65 patients with assault-related maxillofacial fractures treated in the Department of Cranio-Maxillofacial Surgery, University Hospital of Bern between 2000 and 2002. METHODS: The mechanism, the causes of the injuries and the location of the fractures were analysed by reviewing emergency and hospital records. Concomitant injuries were also studied. RESULTS: The mean age of the patients was 33 years with the largest group being below 25 years. The male-to-female ratio was 56:9. The most common causes of assault-related injuries were fights, most frequently facial blows, accounting for 92.5% of all patients. Seventy-six per cent of the fractures occurred in the middle and upper facial skeleton with a predominance of 2:1 for the left side. In 39 patients (60%) surgery was necessary, with a mean hospital stay of 3.3 days. Thirty-five patients (54%) had concomitant injuries. Alcohol and drug abuse was found in 15 patients (23%). CONCLUSION: It seems that mostly young men suffer assault-related maxillofacial injuries. A contributing factor to the increased disposition for violence could be alcohol and drug abuse. Therefore, national prevention programmes for alcohol or drug abuse and addiction might have a positive effect on reducing the incidence of assault-related maxillofacial injuries.     

Maxillofacial fractures sustained in bicycle accidents

The present report is an analysis of 93 patients (52 male; 41 female) treated in 1981-1983 for maxillofacial fractures sustained in bicycle accidents. These accidents accounted for 7.1% of all facial bone fractures treated during the same period. Most accidents were single vehicle accidents (88%) and took place during the summer months. Of the patients, 65% had mandibular fractures, 35% had midface fractures and 5% had fractures in both the middle and lower thirds of the face. Condylar fractures were by far the most common of the mandibular fractures (67%)--a result which differs from studies concerning the profile of mandibular fractures in general. The majority of the middle third fractures were zygomatic (65%). Multiple injuries were diagnosed in 38% of the cyclists and other head injuries were the most common associated injury. Mean hospitalization of the in-patients (38%) was 4.1 days and the average sick leave was 14 days. The results of the study indicate that the use of protective helmets should be strongly recommended to cyclists, although most commercially available helmets do not protect the whole facial area and especially not the chin.     

Traumatic intracranial haemorrhage in conscious patients with facial fractures - A review of 1959 cases

OBJECTIVE: Facial fracture patients who are conscious with a Glasgow Coma Scale (GCS) score of 15 in the absence of clinical neurological abnormalities are commonly not expected to have suffered severe intracranial pathology. However, high velocity impact may result in intracranial haemorrhage in different compartments. METHODS: Over a 7-year period, 1959 facial fracture patients with GCS scores of 15 and the absence of neurological abnormalities were analysed. In 54 patients (2.8%) computed tomography scans revealed the presence of accompanying intracranial haemorrhage (study group). These patients were compared with the 1905 patients without intracranial haemorrhage (control group). RESULTS: Univariate analysis identified accompanying vomiting/nausea and seizures, cervical spine injuries, cranial vault and basal skull fractures to be significantly associated with intracranial bleeding. In multivariate analysis the risk was increased nearly 25-fold if an episode of vomiting/nausea had occurred. Seizures increased the risk of bleeding more than 15-fold. The mean functional outcome of the study group according to the Glasgow Outcome Scale was 4.7+/-0.7. CONCLUSION: Intracranial haemorrhage cannot be excluded in patients with facial fractures despite a GCS score of 15 and normal findings following neurological examination. Predictors, such as vomiting/nausea or seizures, skull fractures and closed head injuries, enhance the likelihood of an intracranial haemorrhage and have to be considered.     

Facial soft tissue injuries as an aid to ordering a combination head and facial computed tomography in trauma patients.

PURPOSE: While the trauma computed tomography (CT) head scan is frequently ordered during resuscitation of multiply injured patients, determining when also to order facial CT in these situations can be difficult. Consequently, facial fractures are commonly missed on initial imaging evaluation. In acute trauma situations, facial soft tissue injury markers are often used to aid in this decision. A study was undertaken to identify exactly which facial soft tissue injuries correlate with facial fractures and which did not. The aim of our research was to compare the facial soft tissue injury patterns of patients receiving a combination head and facial CT who had facial fractures versus those who had no facial fractures. PATIENTS AND METHODS: A retrospective trauma registry review was performed for a 5-year period at Legacy Emanuel Hospital, a level 1 trauma center. The trauma team saw a total of 9,871 trauma patients and 49.9% required head CT as part of their initial evaluation. A total of 777 (15.7%) patients had a combination head and facial CT in which 477 (61.4%) had a facial fracture and 300 (38.6%) had no facial fracture. Statistical significance was established using Bonferroni corrected P values less than .05. RESULTS: Lacerations occurring in areas of the lips, nose, and intraorally, as well as wounds leading to periorbital contusion and subconjunctival hemorrhage, were significantly prevalent in the fracture group. Conversely, scalp lacerations and scalp contusions were significantly higher in the nonfracture group. Other injuries such as lacerations of the tongue, chin, forehead, cheek, ear, eyelid, and eyebrow were indistinguishable between both groups. CONCLUSIONS: Our data demonstrate that there are certain facial soft tissue injury zones that correlate with facial fractures in trauma patients who obtain head CT. We would like to propose that the acronym LIPS-N (Lip laceration, Intraoral laceration, Periorbital contusion, Subconjunctival hemorrhage, and Nasal laceration) be used in conjunction with a physical examination when assessing if a trauma patient who is getting head CT should also get facial CT.     

Maxillofacial injuries in the pediatric patient

Approximately 22 million children are injured in the United States annually. Children are uniquely susceptible to craniofacial trauma because of their greater cranial-mass-to-body ratio. The pediatric population sustains 1% to 14.7% of all facial fractures. The majority of these injuries are encountered by boys (53.7% - 80%) who are involved in motor vehicle accidents (up to 80.2%). The incidence of other systemic injury concomitant to facial trauma is significant (10.4% - 88%). The management of the pediatric patient with maxillofacial injury should take into consideration the differences in anatomy and physiology between children and adults, the presence of concomitant injury, the particular stage in growth and development (anatomic, physiologic, and psychologic), and the specific injuries and anatomic sites that the injuries affect. This comprehensive review, based on the last 25 years of the world's English-speaking surgical literature, presents current thoughts on the anatomic and physiologic differences between adults and children, a synopsis of childhood growth and development, and an overview of state-of-the-art management of the pediatric patient who has sustained maxillofacial injury.     

Cervical spine injuries in facial fracture patients − injury mechanism and fracture type matter

Evidence supports the notion that craniofacial fractures are significant predictors of cervical spine injuries (CSIs), but some debate remains on the injury mechanism of co-existing CSIs in craniofacial fractures and the relationship between CSI and specific facial fractures. In this retrospective study, we aim to assess the incidence rates of specific facial fracture types as well as other important variables and their relationship with CSIs. The primary outcome variable, CSI, and several predictor variables, including facial fracture type, were evaluated with logistic regression analyses. Of 2919 patients, the total CSI incidence rate was 3.0%. Rates of CSI in patients with isolated mandibular fractures (OR 0.26 CI 0.10, 0.63; p = 0.006) were lower than those previously reported, whereas isolated nasal fractures were strongly associated with CSI (OR 2.67 CI 1.36, 5.22; p = 0.004). Patients with concomitant cranial injuries were twice as likely to have CSI (OR 2.00, CI 1.22, 3.27; p = 0.006). Even though there is a strong occurrence rate of CSIs in patients with cranial injuries, clinicians should be aware that patients presenting with isolated facial fractures are at significant risk for sustaining CSIs also.     

Sports-related maxillofacial fractures: a retrospective study of 125 patients

This study assessed the spectrum of maxillofacial fractures sustained during sports in Greece, discuss the aetiology in different sports and suggest protective measures. One hundred and twenty-five patients suffered facial fractures as a result of different sport activities. The factors evaluated were: type of sport involved, age, sex, mechanism of injury, site of fractures, associated non-maxillofacial injuries and mode of treatment. The ratio male to female was 9:1 and the highest incidence of sport-related facial fractures was found in the 21-30 year age group. Football was the most common sport-related to facial fractures and the main mechanism of injury was that of impact against another player's head. The most common were the mandibular fractures, followed by zygoma fractures. Furthermore, the angle of the mandible is the highest risk region for fracture. The majority of patients needed surgical treatment. Facial fractures during sports mainly affect the young and the majority of the patients are amateur athletes. Although these injuries are not usually severe, initial hospitalisation and surgical interventions may be required. Team sports are responsible for the majority of facial fractures.     

The relationship between head injury and facial trauma: a case–control study

Introduction

In spite of anatomic proximity of the facial skeleton and cranium, there is paucity of information in the literature regarding the relationship between head injuries and facial trauma. The objective of our investigation was to evaluate the pattern of head injuries in patients with maxillofacial trauma, and to study their relationship.

Material and methods

We evaluated 2,692 patients with maxillofacial trauma admitted to the Besat hospital, Hamedan, Iran between 2007 and 2010. Patients with associated head injury (302 cases; study group) were compared with those without head injury (2,390 cases; control group).

Results

In our cohort, the rate of head injuries associated with facial bone fractures was 23.3 %. The most common associated head injury was concussion, followed by cerebral contusion and skull fractures. In the unadjusted analysis, motorcycle and car accidents were significantly more frequent in the study group, while stumbling, sports injuries, and work-related injuries were significantly more common in the control group (p?<?0.001). Except for Lefort III fractures which was not significantly different between groups, all facial fractures occurred more frequently in the study group (p?<?0.001). Logistic regression analysis demonstrated that motorcycle accidents (211-fold), car accidents (139-fold), violence (69-fold), falls (66-fold), frontal sinus fractures (84.5-fold), and Lefort II fractures (27-fold) were the strongest predictors of head injuries.

Discussion

Present study revealed that fracture of facial bones, especially bones that are in anatomic proximity to the cranium and need a high magnitude of trauma energy to be fractured, was marker for an increased risk of head injuries.     

A one-year review of craniofacial injuries in amateur soccer players

The purpose of this study was to investigate the rate of craniofacial injuries in amateur soccer and help us better understand the nature of these injuries. Retrospective study was carried out using records from the patients with craniofacial injuries associated with soccer activities. All data were collected on the basis of sex, age, type and anatomic site of the injury. In the one-year period of this study, 11/53 cases with craniofacial injuries associated with soccer activities have been treated in our clinic. The highest incidence was in the 18 to 24 year age group (mean age 20.7) with male propensity. The majority of the patients suffered from dento-alveolar fractures (36%), followed by temporomandibular joint disorders (27%), mandibular fractures (27%), and nasal fractures (9%). The most common cause of the fractures was impact against another player (63.6%), followed by impact against equipment (18.2%) and impact against the ground (18.2%). These results show that there is a high risk of potential oral and craniofacial injury during soccer activities.     

Lateral impact in closed head injury: a substantially increased risk for diffuse axonal injury--a preliminary study.

OBJECTIVE: Assessment, whether location of impact causing different facial fracture patterns was associated with diffuse axonal injury in patients with severe closed head injury. METHODS: Retrospectively all patients referred to the Trauma Unit of the University Hospital of Zurich, Switzerland between 1996 and 2002 presenting with severe closed head injuries (Abbreviated Injury Scale (AIS) (face) of 2-4 and an AIS (head and neck) of 3-5) were assessed according to the Glasgow Coma Scale (GCS) and the Injury Severity Score (ISS). Facial fracture patterns were classified as resulting from frontal, oblique or lateral impact. All patients had undergone computed tomography. The association between impact location and diffuse axonal injury when correcting for the level of consciousness (using the Glasgow scale) and severity of injury (using the ISS) was calculated with a multivariate regression analysis. RESULTS: Of 200 screened patients, 61 fulfilled the inclusion criteria for severe closed head injury. The medians (interquartile ranges 25;75) for GCS, AIS(face) AIS(head and neck) and ISS were 3 (3;13), 2 (2;4), 4 (4;5) and 30 (24;41), respectively. A total of 51% patients had frontal, 26% had an oblique and 23% had lateral trauma. A total of 21% patients developed diffuse axonal injury (DAI) when compared with frontal impact, the likelihood of diffuse axonal injury increased 11.0 fold (1.7-73.0) in patients with a lateral impact. CONCLUSIONS: Clinicians should be aware of the substantial increase of diffuse axonal injury related to lateral impact in patients with severe closed head injuries.     

Prevalence of cervical spine injuries in patients with facial trauma

OBJECTIVE: Injuries to the spine may accompany facial trauma. By using a large computerized database the goal of this case control study was to assess the association between facial and cervical spine injuries among patients sustaining facial trauma. STUDY DESIGN: During a period of 4 years (1995 to 1998) 3083 patients, 10 years or older, with facial injuries were admitted to the University Hospital of Innsbruck's Department of Oral and Maxillofacial Surgery for facial trauma. Records were analyzed for cause of injury, age and gender distribution, frequency and type of injury, and frequency of cervical spine injuries in relation to facial trauma and concomitant injuries. Two hundred six (6.7%) of these patients had experienced a concomitant cervical spine injury (case group). All other patients (2877) were assigned to the control group of facial trauma only. RESULTS: Facial trauma patients with concomitant cervical spine injuries were significantly older (mean age, 42 vs 34 years); no difference existed for the female/male ratio of 30:70. Sports trauma was the main cause of facial trauma in the control group (37.4%), yet traffic accidents accounted for 43.7% of combined facial and cervical spine injuries in the case group. Central mid face fractures dominated in the case group and lateral mid face fractures in the control group. In the case group cervical spine fractures and dislocations occurred in 19.2%. None of them showed evidence of paralysis. Concomitant brain injuries occurred in 21.6% of the case group and 8.8% of the control group. For patients sustaining facial trauma, logistic regression analysis revealed reduced risks for additional cervical spine injuries in younger patients, female patients, absence of brain injury, and in patients with facial soft tissue lesions alone (58.2%) or dental trauma alone (77.5%). CONCLUSION: The results of this study underline the importance of proper clinical and computed tomographic evaluation in cases of facial fractures for recognition of additional cervical spine trauma. Detection of cervical spine trauma can be missed, especially when pain or symptoms from other parts of the body dominate. The typical patient with concomitant neck and facial trauma is male, 40 years old, and usually involved in a traffic accident.     

Maxillofacial fractures related to work accidents

Work-related maxillofacial fractures were studied retrospectively over a six-year period. There were 98 cases accounting for 4.5% of all facial bone fractures treated in our hospital between 1981 and 1986. Of the patients, 89.8% were male. The mean age of the injured was 36.4 years. The incidence of work-related maxillofacial fractures was 0.37 per 1000 workers. Most of the injuries (66%) occurred in factories and construction work. Such work was associated with an to 15 times higher risk of maxillofacial fracture than service and office work. Of the fractures, 20.4% were sustained on the way to or coming from work. At the place of work, the commonest causes of injury were blows from objects or falls from a height (70%). On the way to or coming from work, the aetiological factor was most often a traffic accident. Assault and battery had caused facial bone fractures in 11.2% of cases. Fifty-five patients with midface and 45 patients with mandibular fractures were found, of these, 8 patients had bimaxillary fractures. In 6 cases, only dentoalveolar fractures were found. Of the patients, 55.1% were treated operatively. Sixty-six patients were hospitalized, the mean length of hospital stay being 3.2 days (range 1-12 days).     

Football-related maxillofacial injuries

Maxillofacial injuries sustained playing sports are becoming increasingly common, and in the UK where football is the most popular team sport, associated maxillofacial injuries are a regular occurrence. This study retrospectively examined data on patients who were referred with facial injuries sustained playing football between 2007 and 2019 (n = 265). Demographics, mechanism of injury, diagnosis, and treatment received were analysed. The mean (SD) age was 25 (11.0) years (range 3-85) and there was a strong male predominance (n = 256, 97% male). Facial fractures were diagnosed in 143 (54%) patients. The most common injury was a midface fracture and the most common mechanism of injury was a clash of heads. Patients with a facial fracture were significantly more likely to have sustained a concurrent head injury (p = 0.006). Those who were elbowed or punched were significantly more likely to have a facial fracture than a soft tissue or dentoalveolar injury (p ≤ 0.05). Players who clashed heads were significantly more likely to have a midface fracture (p ≤ 0.001). In conclusion, football-related maxillofacial injuries predominantly affect young adult males following a clash of heads. An elbow or punch to the face carries a significant risk of facial fracture and concurrent head injury. Therefore, to reduce the percentage of maxillofacial injuries seen in this sport, observed intentional contact between players, using an elbow or fist to the face in particular, must continue to carry the highest sanction.     

Alcohol and interpersonal violence may increase the severity of facial fracture

The association between alcohol and interpersonal violence has been established in studies from a number of countries. We aimed to determine whether alcohol was a contributing factor in the incidence or severity of facial trauma. For 15 months we prospectively studied patients with facial fractures who presented for oral and maxillofacial review. Severity of injury was assessed using the maxillofacial injury severity score (MFISS). Of the 255 patients with facial trauma who presented to our tertiary referral centre, 202 had fractures of the facial skeleton. Most presentations were secondary to interpersonal violence (n=105, 52%), and 91 (87%) of these involved alcohol. Overall, alcohol was involved in 53% of cases (n=107). The relative risk of requiring surgical intervention when alcohol was involved was 1.61 (CI=1.12-2.32). Alcohol significantly increased the severity of facial fracture for both MFISS: alcohol (n=107) mean (SD) 11.43 (7.63); no alcohol (n=95) mean (SD) 6.87 (6.22) (p<0.05). Interpersonal violence also increased the severity of facial fracture: interpersonal violence (n=105) mean (SD) 11.06 (6.68), no interpersonal violence (n=97) mean (SD) 7.37 (7.59) (p<0.05). Patients whose facial fractures are the result of interpersonal violence have more severe injuries and are more likely to require surgery if alcohol is involved. This results in a heavier surgical workload, and is an economic and social burden to the community. Primary prevention strategies will have an important role in reducing such injuries.
