Sulcus Vocalis Treated with Autologous Collagen Injection
Background and Objectives
s : Despite of numerous treatment modalities for glottic insufficiency, it still remains unresolved problem. Recently, autologous collagen injection was introduced as a new treatment for glottic insufficiency. This study was attempted to evaluate the efficacy of this treatment modality.
Materials and Method
s : Ten patients diagnosed as symptomatic sulcus vocalis with glottic insufficiency and agreed with this procedure were selected. Injectable collagen was obtained from the patient's dermis. It was injected into the pathologic area of the vocal fold. After injection, 4 of 10 patients were 1311owe4 up more than 5 months, and their voice were evaluated prior to injection and at 5 months after injection, using subjective, perceptual, aerodynamic, acoustic and videostroboscopic assessments.
: In the aerodynamic assessment, 2 of 4(50%) patients was improved in MFR(mean flow rate), but no change was noted in MPT(maximum phonation time). In the acoustic assessment, no definite improvement was noted. In the subjective and perceptual assessments, 2 of 4(50%) patients was improved. In the videostroboscopic assessment, chink was reduced but still remained. Serious complication was not noted.
: Autologous collagen injection was reported as ideal treatment for glottic insufficiency, but our results were relatively unsatisfactory. But considering that our study is preliminary, it is too hasty to determine the efficacy of autologous collagen injection. We think that further study is required.
