鼻内镜下低温等离子射频切除术治疗鼻咽血管纤维瘤的初步观察

Objective To evaluate the feasibility of endoscopic surgery using the low-temperature plasma radiofrequency for nasopharyngeal angiofibroma (NA). Methods The clinical data of 4 patients treated between December 2005 and August 2009 were retrospectively analyzed. The tumor in one patient was at stage Ⅰ and three patients were at stage Ⅱ, all these patients were treated by endoscopic surgery using the low-temperature plasma radiofrequency under controlled hypotension anesthesia. Preoperative angiography and embolisation were underwent in all patients. Bipolar coagulation was used to help hemostasis during operation. Results The tumor in all 4 patients was completely removed. The operation time was 60,80, 110, 90 min respectively. The blood loss was 250, 250, 320, 280 ml respectively. Neither blood transfusion nor complications were encountered perioperatively. Follow-up ranged from 6 months to 4 years,none of the patients recurred. Conclusions Endoscopic surgery using low-temperature plasma radiofrequency for nasopharyngeal angiofibroma has many advantages such as less bleeding and total tumor removal. It is a minimally invasive surgical method for nasopharyngeal angiofibroma.     

Transoral robotic nasopharyngectomy for local recurrent nasopharyngeal carcinoma北大核心CSCD

Objective To investigate the safety, efficacy, locally control and survival results of transoral Da Vinci robotic surgery for salvage treatment of locally recurrent nasopharyngeal carcinoma. Methods This retrospective study included 33 patients with locally recurrent nasopharyngeal carcinoma (stage rT1‑2, partial rT3) underwent transoral Da Vinci robotic surgery between October 2017 and January 2020. There were 20 males and 11 females, with an average age of (47.9±10.5) years. The lesions were localized in nasopharyngeal cavity in 14 cases, with extending to parapharyngeal space in 6 cases and the floor of sphenoid sinus in 13 cases. Transnasal endoscopy was used to assist surgery if necessary. SPSS 25.0 statistical software was used for statistical analysis. Results Transoral robotic nasopharyngectomy was successfully performed in all cases without conversion to open surgery, of which 13 cases were combined with transnasal endoscopic surgery. The average operation time was (126.2±30.0) min, ranging from 90 to 180 min. The postoperative pathological margin was R0 (31 cases) and R1 (2 cases), with no tumor residue. Complications of surgery mainly included symptoms of headache, nasal dryness and velopharyngeal insufficiency without nasopharyngeal hemorrhage. Follow‑up time was from 3 to 54 months. One case had tumor recurrence 11 months after operation, 1 case had ipsilateral cervical lymph node metastasis 27 months after operation, 2 cases had distant metastasis and 1 case died of nasopharyngeal hemorrhage 3 months after operation. The 1‑year, 2‑year and 3‑year overall survival rates were 97.0%, 96.0% and 92.9%, respectively and the local recurrence free rates were 97.0%, 95.7% and 91.7%, respectively. Conclusion Transoral robotic nasopharyngectomy is safe and feasible for local recurrent nasopharyngeal carcinoma in selected patients, with higher local control rate and quality of life. © 2022 Chin J Otorhinolaryngol Head Neck Surg.

鼻腔筛窦鳞状细胞癌146例治疗分析

Objective To evaluate the treatment outcome of different therapeutic modalities for squamous cell cacinoma of the nose and ethmoid sinus and prognostic factors. Methods One hundred and forty-six cases of squamous cell carcinoma of the nose and ethmoid sinus treated from 1990 to 2007 were reviewed. Of the 146 cases,28 were at stage Ⅰ or Ⅱ ;46 stage Ⅲ ;72 stage Ⅳ. Forty-one patients were treated with preoperative radiation plus surgery( R + S) ,22 patients with surgery plus postoperative radiation ( S + R), 5 patients with surgery alone ( SA ), 78 patients with radiotherapy alone (RA). Results The overall 5 year survival rate of 146 patients with squamous cell carcinoma of the nose and ethmoid sinus was 49. 1%. The 5 year survival rate of the patients at stage Ⅰ and Ⅱ was 95. 7% ,while the rate was 59. 8% in the patients at stage Ⅲ and 28. 2% in the patients at stage Ⅳ ( x2 = 24. 15, P < 0. 05). The 5 year survival rate was 57.7% in R+S group,60.4% in S+R group, 100% in SA group,and 38.8% in RA group,respectively(P >0. 05). The 5 years survival rate of N + patients was lower than that of NO( x2 = 12. 326,P < 0. 05). Local recurrence and distant metastasis were main causes of death. Cox analysis showed TNM stage and differentiation of tumor were independent significant prognostic factors. Conclusions The higher survival rate of patients with squamous cell carcinoma of the nose and ethmoid sinus was obtained from combined therapy R + S or S + R. SA gave ideal results for early lesions(stage Ⅰ and Ⅱ ).

Levels of biological markers of nitric oxide in serum of patients with squamous cell carcinoma of the oral cavity

The aim of the study was a determination of the levels of nitric oxide（NO）and its biological markers such as malonyldialdehyde（MDA）and nitrotyrosine in the serum of patients with squamous cell carcinoma（SCC）of the oral cavity and identification of the relationships between NO and those markers.These studies were performed on patients with SCC of the oral cavity before and after treatment.Griess reaction was used for the estimation of the total concentration of NO in serum.The nitrotyrosine level in serum was assessed with an enzyme-linked immunosorbent assay（ELISA）kit,and MDA level using a spectrophotometric assay.Higher concentrations of NO in blood serum were determined in patients with stage IV of the disease before treatment in comparison to the control group and patients with stages II and III of the disease.Moreover,higher concentrations of MDA and nitrotyrosine were determined in the serum of patients in all stages of the disease in comparison to healthy people.After treatment,lower concentrations of NO in the serum of patients with stage IV of the disease were observed in comparison to the amounts obtained prior to treatment.In addition,lower levels of nitrotyrosine in the serum of patients with all stages of the disease were recorded,whereas higher concentrations of MDA were determined in these patients in comparison to results obtained before treatment.The compounds formed with the contribution of NO,such as MDA and nitrotyrosine,may lead to cancer progression in patients with SCC of the oral cavity,and contribute to formation of resistance to therapy in these patients as well.Moreover,the lack of a relationship between concentrations of NO and MDA,and between NO and nitrotyrosine in serum suggests that the process of lipid peroxidation and nitration in patients with SCC does not just depend on NO.     

神经导航及内镜辅助下经鼻蝶显微切除无功能性 垂体大腺瘤的近期疗效分析

ObjectiveTo investigate the short term effect of neuronavigator and endoscope assisted endonasal trans sphenoidal surgery for patients with nonfunctioning pituitary macroadenomas.MethodsClinical data of 62 patients with nonfunctioning pituitary macroadenomas received surgical treatment in our department from Jan 2013 to Sept 2014 were retrospectively analyzed. 62 patients were divided into two groups by whether to use neuronavigator and endoscopic technology or not, i.e. study group (32 cases) and control group (30 cases). Pituitary adenoma resection was performed with assistance of endoscope and neuronavigation in the study group. The indexes including surgery time, postoperative hospitalization duration, postoperative complications, changes of serum endocrinology, MRI, the residual and recurrence rates in the two groups were recorded and analyzed.ResultsThe time of hospital stays (6.6±0.7 d) in the study group was significantly less than that in control group (8.1±0.8 d). The postoperative complication rate (including transient diabetes insipidus, cerebrospinal fluid rhinorrhea, electrolyte disturbances, postoperative bleeding in the tumor cavity,hypopituitarism) in study group was also significantly lower than that in the control group (P<0.05). The postoperative remission rate of study group was significantly higher than that of the control group. The residual (2 cases) and recurrence (0 cases) rates in the study group were significantly lower than those in the control group (9 cases and 5 cases). According to the Knosp grade, the residual rate of the patients with Knosp grade=2 in the study group was lower than that of the control group, and the difference was statistically significant (P<0.05).ConclusionThe neuronavigator and endoscopic technology contribute to decrease the occurrence of the postoperative complications, to reduce residual and recurrence rate, and to improve the gross total resection of tumor, is therefore effective for the treatment for patients with nonfunctioning pituitary macroadenomas.     

congenital cholesteatoma of the middle ear-a report of 10 cases

Objectives To study clinical, imaging features and treatment outcomes of congenital cholesteatoma of middle ear (CCME). Methods This is a retrospective review of 10 CCME cases selected from 952 cholesteatoma cases treated between January 1995 and December 2005 at the Department of Otolaryngology-Head and Neck Surgery, Chinese PLA General Hospital. The main outcome measures were the site of origin, clinical features, surgical findings, imaging characteristics and hearing results. Results The mean age of the 10 patients was 16 years(ranged from 10 to 24 years), with 6 being older than 18 years. There were 7 males and 3 females. The average delay to diagnosis was longer than 2 years. The mean preoperative PTA was 55 dB HL, with a mean ABG of 45 dB. Typical cholesteatomas were seen behind the tympanic membrane in the superoposterior quadrant on otoscopy only in 2 patients. High resolution CT was completed in all patients. Most of the patients(8/10) were diagnosed with otosclerosis or ossicular abnormality before operation. All patients underwent a one-stage tympanoplasty following transmeatal explorative tympanotomy and complete cholesteatoma removal, except one, who underwent a CWU mastoidectomy due to extensive cholesteatoma involvement. The choleasteatoma lesion was confined to the superoposterior mesotympanum in all patients. The mean postoperative PTA was 20 dB HL. All patients were followed-up for at least 1.5 years postoperatively. Revision procedures were performed in 2 patients for hearing deterioration. No residual or recurrence of cholesteatoma was found. Conclusion CCME is a rare disease that often gets delayed diagnosis. Residual lesions and the prognosis mainly depend on the extent of the lesion.     

Stability of computed tomography densitometry in patients with otosclerosis:a two-year follow-up

Objectives:To quantify the progression of otosclerosis in the unoperated ear between two stapedotomy procedures for patients with bilateral otosclerosis which can help to determine whether a HRCT scan should be re-performed before the second surgery for patients who already received HRCT imaging before the initial surgery.Methods:35 patients who underwent bilateral stapedotomy were included.Two rounds of HRCT examination and audiometry were performed at the time of the first surgery and second surgery on the ear that was not operated on during the initial surgery.The relationship between the changes in HRCT densitometry and audiometry over time was analyzed.Results:The second round of HRCT did not add significant information about the changes to the otosclerosis lesions in either the imaging diagnosis or the HRCT density values except for small changes in the HRCT densitometry readings at the area anterior to the inner auditory(P=0.01).While the changes in HRCT manifestation are small,changes near the fissula ante fenestram(FAF)were still positively correlated with the air bone gap(ABG)of patients(p=0.031,r=0.388).Conclusions:The progression of lesions in otosclerosis is slow resulting in small and insignificant changes to the HRCT features.Therefore,a repeat HRCT evaluations prior to surgery is not necessary for patients who have had a previous HRCT evaluation within 2 years of the operation.The small changes in HRCT manifestation near the FAF were still correlated with negative effects on the ABG which could cause worsened hearing thresholds over this timeframe。
