Objective To compare the clinical effect between CO2-1aser assisted and cold instrument assisted suspension laryngoscopic surgery for vocal fold cyst.Methods From January, 2011 to December, 2014, 72 patients with vocal fold cyst, which diagnosed by strobolaryngoscopy, were randomly divided into CO2-1aser assisted group and cold instrument group.Strobolaryngoscopy, acoustic analysis and perceptual voice analyses were performed on each patient before surgery, 1 month, and 3 months after surgery, respectively.Results All operations were successfully completed.The complete vocal fold cyst resection rate of CO2-1aser assisted group was significantly higher than cold instrument group (29/36, 80.5％ vs 21/36, 58.3％, P ＜ 0.05), especially the left vocal fold cyst (13/16, 81.3％ vs 9/19, 47.4％, P ＜ 0.05).The complete right vocal fold epidermoid cyst resection rate was significantly higher than retention cyst (17/19, 89.4％ vs 11/18, 61.1％, P ＜ 0.05).Two recurrent cases were found in cold instrument group but no recurrent cases in CO2-laser assisted group (0/36, 0％ vs 2/36, 5.6％, P ＞ 0.05).Correlation analysis showed that vocal fold cyst recurrence was related to complete resection rate and has no relation with surgical methods, histopathological types and position.Subjective and objective assessment of voice quality in preoperative, 1-month postoperative and 3-month postoperative were similer between CO2-1aser assisted group and cold instrument group (P ＞ 0.05).Conclusion The CO2-laser assisted suspension laryngoscopic surgery for vocal fold cyst, can increase the surgical precision, reduce the left hand impact, improve the complete resection rate and reduce the recurrence rate.

OBJECTIVE: To repair the postoperative tissue detect of the base of tongue cancer in advanced patients. METHOD: There were 30 patients of medium-high differentiation squamous cell carcinoma(SCC) included in this study. According to the TNM staging of AJCC 2002, there were 4 cases of T2N1M0, 7 of T3N1M0, 10 of T3N2M0, 4 of T4N1M0 and 5 of T4N2M0. Surgical approach of the primary lesion: 12 with transhyoidpharyngotomy approach and 18 with mandibulotomy approach. All cases accepted radiotherapy 4-6 weeks after surgery. RESULT: Twenty-five cases were reconstructed with pedicle pectoralis major myocutaneous flaps, and all them survived. Among them, 1 flap was partial split with surrounding tissue spontaneously, and another flap had partial tissue necrosis, however, both flaps grew well with dressing and other local treatment. Other 5 cases were reconstructed with free anterolateral myocutaneous flaps. Among them, 1 flap had partial tissue necrosis, but had a secondary healing after removing necrotic tissue via mouth approach. All 18 patients of larynx-preservation had tracheal tube pulled out. The 3-year survival rate was 68% and the local control rate was 87%. CONCLUSION Pedicle pectoralis major myocutaneous flaps and free anterolateral myocutaneous flaps were alternative donor area for repairing postoperative tissue defect of the base of tongue; The former was preferred, and the latter was concealed so as to be a kind of effective method, which need adept technique of microsurgery.

Objective: To evaluate the diagnostic value of the endoscopic biopsy operation to the lesions of the skull base in the patients with nasopharyngealcarcinoma after radiotherapy. Methods: From February 2006 to February 2010, 84 patients with nasopharyngeal carcinoma suffered from the lesions of the skull base after radiotherapy were included in this study. The relationship between the pathologic results of endoscopic biopsies from the skull base and the imaging results by Magnetic Resonance Imaging(MRI) was compared and discussed. The relationship between the pathologic results and more than 2-years′ follow-up was also investigated. Results: There were 71 cases with clivus, 5 cases with pterygopalatine fossa and infratemporal fossa, 4 cases with parapharyngeal space, and 4 cases with cavernous sinus. The pathologic results of endoscopic biopsies indicated that 35 cases with recurrence including 30 case with poorly differentiated squamous cell carcinomas, 5 cases with cancer nests, 49 cases with non-tumor. Chi-square test showed that there was close relationship between MRI and pathologic results (P<0.05). In the patients followed up over 2 years, the pathologic results showed 28 cases with recurrence, 48 cases with non-tumor. MRI showed 36 cases with recurrence, 40 cases with non-tumor. But during follow-up, 30 cases were proved to be recurrent and 46 cases had non-tumor. However, Chi-square test showed that there was no statistically significance between the pathological results and follow-up(P=0.62). The sensitivity, specificity and diagnostic accuracy of the endoscopic diagnosis were 90.0%, 97.8% and 95.0%. Chi-square test also showed that there was no statistically significance between MRI and follow-up (P=0.24). The sensitivity, specificity and diagnostic accuracy of MRI were 80.0%, 73.9% and 76.0%. Conclusions The endoscopic method is a specific, sensitive, safe, effective and minimally invasive in diagnosis of lesions of the skull base in postradiotherapeutic patients with nasopharyngeal carcinoma.

Objective: To evaluate the significance for the preservation of the supraclavicular nerve in endoscopic thyroidectomy via gasless anterior chest approach. Methods: We retrospectively evaluated 168 patients who underwent unilateral endoscopic thyroidectomy via gasless anterior chest approach, with preservation of the medial branch of the supraclavicular nerve in 110 patients and not in other 58 patients. Semmes-Weinstein monofilament (SWM) test and a visual analogue scale (VAS) were used to assess the recovery of sensation in anterior chest within 1-12 months postoperatively. Difference in the scores of SWM or VAS between groups was tested with Mann-Whitney U test, and the rates of SWM and VAS scores returning to normal levels in individual periods after surgery was compared with Chi-square test. Results: The preserved group showed more favorable results than the non-preserved group in both SMW and VAS scores. Compared to control group, SWM score in preserved group possessed a higher rate recovery to normal level at any period after operation, which was close to complete normality in 7-9 months postoperatively, and SWM score in non-preserved group was still partially normal in 10-12 months from surgery. Preferable results for VAS were also found in the preserved group, except no significant difference in VAS between groups in1-3 months or 10-12 months after operation. Conclusion Preservation of the medial branch of the supraclavicular nerve in endoscopic thyroidectomy via gasless anterior chest approach can improve sensation recovery in anterior chest, thus improving postoperative quality of life of patients.

Objective: To assess the safety and curative effect of gasless endoscopic selective lateral neck dissection (GESLND) via an anterior chest approach for papillary thyroid carcinoma (PTC). Methods: Eighteen patients with PTC(T1-2N1bM0, size<3.0 cm), having GESLND via an anterior chest approach, were included from November 2008 to December 2016. Results: GESLND via an anterior chest approach was successfully performed in all 18 PTC patients (seven male and eleven female) with 83.3% of T1 and 16.7% of T2. The mean operative time of selective lateral neck dissection was 73 min (range 51-92 min). The mean of intraoperative bleeding was 61.1 ml (range 30-120 ml). No major complications occurred except one transient hypoparathyroidism. No residual thyroid glands were detected on ultrasonography and thyroglobulin was(0.73±0.16)ng/ml three months postoperatively. The median of follow-up was 54.5 months (range 6-104 months). No recurrence disease was observed in any patient on ultrasonography, computer tomography, thyroglobulin or selective iodine-131 scan during the follow-up period. The cosmetic result and functional preservation was excellent, when the assessments were performed three months postoperatively. Conclusion GESLND via an anterior chest approach is feasible and safe for selected PTCs, with superior appearance.

Objective:To translate the University of Rhode Island Change Assessment of voice scale（URICA-Voice） into Chinese and test its reliability and validity. Methods:The URICA-Voice scale was converted into Chinese by literal translation, cultural adjustment, expert consultation, pre-investigation, and back translation. Convenience sampling was used to recruit patients at four speech therapy centers from February to May 2022. Then the Chinese version of the scale was distributed to them, and the reliability and validity of the scale were tested after data collection. Cronbach ɑ was used to evaluate the reliability. The critical ratio method and Pearson correlation coefficient were used for item analysis. Item-level content validity, scale-level content validity, and confirmatory factor analysis were used to test the validity of the scale. Results:A total of 247 valid questionnaires were collected. ①Item analysis: the critical ratios between a high-score and low-score groups of 32 items were all statistically significant（P<0.01） and all the critical ratios were above 3.00. The Pearson correlation between 32 items and the total score was significant（P<0.01）. ②Validity analysis: I-CVI=1.00, S-CVI/Ave=1.00, χ²/df=2.30, RMSEA=0.07. Except for item 9 and 23, the standardized factor loading coefficients of other items were all above 0.50. AVE of the four dimensions of the scale was all above 0.50, and the combined reliability of the four dimensions was all above 0.70. The correlation coefficients between dimensions were less than the square root of the AVE of the dimension itself. ③Reliability analysis: the Cronbach ɑ of the whole scale was 0.94, and the Cronbach ɑ of the four dimensions were 0.88, 0.92, 0.94, and 0.88 respectively. Conclusion:The Chinese version of URICA-Voice has good reliability and validity, and can be used as a specific measurement tool for evaluating the compliance of voice training in China.

Objective:The aim of this retrospective study is to evaluate the safety and efficacy of tislelizumab in patients with recurrent/metastatic head and neck squamous cell carcinoma. Methods:Six patients with recurrent/metastatic head and neck squamous cell carcinoma who received tislelizumab monotherapy in our hospital from 2018 to 2020 were retrospectively analyzed. The information of sex, age, TNM stage, efficacy, and adverse reactions were collected. All patients were recruited from the RATIONALE 102 study. The primary end point was the objective response rate, and other end points included progression-free survival and overall survival. We performed tumor immune-related gene sequencing and transcriptome sequencing analysis on the tumor tissues of the patient, and used bioinformatics methods to enrich immune cells and analyze signaling pathways. All analyses were performed using R 4.1. 0 software, SPSS Statistics 24.0 software and GraphPad Prism 8. Results:As of May 31, 2020, the median follow-up time was 26.35 months. The objective response rate with tislelizumab was 50.0%, the median progression-free survival was 6.44 months, and the estimated median survival was 20.07 months. The incidence of grade 3 or higher adverse reactions was 66.7%, including hyponatremia, hypokalemia, hypercalcemia, etc. The expression of macrophage, Treg and neutrophil-related genes are higher in immune-sensitive patients, and the signaling pathways of the intestinal immune network for IgA production, graft versus host disease and autoimmune thyroid disease are significantly activated. Conclusion:Tislelizumab was found to be controllable and tolerable in patients with recurrent/metastatic head and neck squamous cell carcinoma. The response to tislelizumab is related to immune cell infiltration and activation of immune-related signaling pathways.
