ABSTRACT
Objective: To assess voice outcomes after surgical technique for typeⅡ and type Ⅲ sulcus vocalis. Methods: The data of 39 cases of bilateral type Ⅱ-Ⅲ sulcus vocalis were collected and analyzed retrospectively. There were 29 patients with bilateral type Ⅲ sulcus vocalis, and 10 patients with type Ⅲ on one side and typeⅡon the contralateral vocal cord. All of vocal cords were applied autologous anterior rectus sheath fascia transplant, and 68 sides of vocal cords with type Ⅲ sulcus vocalis were also applied autologous fascia and fat injection. Two male patients, whose results from transplant and injection were not satisfied, were carried out cricothyroid myotomy one year after surgery. Subjective and objective voice evaluations were performed before and after operation. Results: One patient was found mild adhesion on the middle part of vocal cords, and all the other 38 patients recovered well and there were no complications. During 5-6 weeks after surgery, breathy voice was the feather. Then vocal quality and glottal closure were gradually improved and became steady in 12 months. It showed that all the subjective and objective parameters, except for fundamental frequency, were significantly improved (P<0.05), and obvious improvement was achieved in glottal closures and mucosal waves in 35 patients. Three patients obtained no significant vocal quality improvement after transplant and injection surgery, and two male patients of them achieved improvement in mucosal waves and MPT after bilateral cricothyroid muscle amputations. One patient, who was revealed with mild adhesion, achieved a satisfied result after adhesion separation and suture. All the patients who originally had feelings of fatigue and voice discontinuity during phonation gained si gnificant improvement postoperatively. Steady function with no complications was observed during the 36 months (up to 5 years in 20 patients) follow-up period. Conclusions: Autologous fascia transplantation combined fascia and fat injcetion can lead to excellent long-term results, and it is a good treatment option for pathologic sulcus vocalis. Cricothyroid muscle amputations can reduce the tension, and may improve vibration property of the vocal fold in patients with pathological sulcus vocalis.
