Unusual presentation of 42 foreign bodies in a child's maxilla

The diagnosis of foreign bodies (such as radiolucent bristles) in the maxillary sinus, particularly in a child, is difficult. We report an unusual case of a 9-year-old boy who presented with 42 bristles in his left maxillary sinus. The presence of these foreign bodies was noted only during operation for removal of nasal polyps. All the foreign bodies were removed at the same operation. The route of entry of the foreign bodies was found to be a rare self-inflicted oroantral fistula in the interdental region of the upper premolar and molar teeth.     

Image guided surgical navigation for removal of foreign bodies in the head and neck

INTRODUCTION: The removal of foreign bodies in the head and neck area is often a surgical challenge due to a combination of difficult access and a close anatomical relationship of the foreign body to vital structures. Recent developments in computer-assisted surgery (CAS) have brought major improvements to the operating rooms for maxillofacial surgeons. The purpose of this paper is to report our experience in computer assisted removal of foreign bodies from the head and neck area, based on various clinical cases. PATIENTS: Computer assisted removal of foreign bodies from the head and neck area was performed in 11 patients. Three patients sustained gun shot wounds with remaining projectiles or fragments in the soft tissue. In six cases, objects related to a preceding surgical intervention were removed. Two patients presented with dislocated teeth in the facial or cervical soft tissues after 3rd molar surgery. METHOD: For surgical planning and intra-operative navigation, a computer based image guided surgery system (VectorVision(2), BrainLab) was used. RESULTS: In 10 of 11 cases the foreign bodies could be removed without major complications by a minimal invasive manner. More than 40 % of surgery time could be saved compared to similar interventions operated upon using conventional methods. CONCLUSION: In our opinion, the use of a computer based image guided surgical system is of great benefit when removing foreign bodies from the head and neck area. The minimally invasive access helps to prevent major complications such as injury to vital structures and allows a quicker operation.     

Innovative uses for hypodermic needles in endodontics.

Unusual objects in the root canal of deciduous teeth: a report of two cases

Accidental foreign body ingestion or aspiration is a common problem in children. Children often have a habit of inserting objects into their mouth. Some of these objects can be accidentally ingested or even aspirated which can be frightening and a stressful experience. But the presence of foreign objects in the teeth are rare. The foreign objects in the teeth may act as a potential source of infection and pain. In most of the cases, children avoid informing their parents due to fear of punishment. This paper presents two cases of foreign objects embedded in the deciduous teeth. In both the cases, parents were not aware of foreign body ingestion by their children.

Removal of a large number of foreign bodies in the maxillofacial region with navigation system

The removal of a large number of foreign bodies in the maxillofacial region can be complicated and challenging. In this case report, a specific strategy for removal of multiple foreign bodies in the maxillofacial region is presented. A girl diagnosed with 24 foreign bodies in her left lower face and neck underwent the surgery using a computer‐assisted navigation system. A specific strategy was used in this case, which included from one sub‐region to the next and from the easiest to the most difficult. This strategy is recommended for the removal of a large number of foreign bodies in the maxillofacial region with a navigation system.     

Penetrating injuries to the maxillofacial region

The cases of 37 patients who had incurred penetrating injuries to the maxillofacial region, with retention of foreign bodies, are described. Primary surgery was performed when possible. In some cases the foreign bodies were removed several years after the injuries, and in others the objects were never removed. Methods for locating and removing foreign bodies lodged within the maxillofacial region are discussed.
