Abstract:ObjectiveTo investigate the effect of the microsurgical flap suture technique under self-retaining laryngoscope for vocal cord benign lesions.Methods46 cases of vocal cord benign lesions (including 12 cases of Reinke’s edema, 24 of vocal cord polyp and 10 of vocal cord cysts) underwent microsurgical flap suture under self-retaining laryngoscope. Resection of the pathological tissues and microscopic suture of the mucosal flaps under self-retaining laryngoscope were performed to all the patients. Before operation, one month and 3 months after operation, all the patients underwent stroboscopy, GRBAS evaluation, voice handicap index (VHI) and so on. For voice acoustic analysis, parameters such as Jitter, Shimmer, maximum phonation time (MPT), dysphonia severity index (DSI) and so on, were included.ResultsAll the patients underwent the operation safely. The lesions were resected microscopically and the mucosal flaps were sutured smoothly by the microsurgical flap suture technique. Postoperative stroboscopy detected smooth mucosa and favourable closure of vocal cords with almost normal mucosal wave in all the patients. Voice analysis revealed that the postoperative parameters were better than the preoperative ones.ConclusionThe microsurgical flap suture technique under self-retaining laryngoscope is effective in protecting vocal cord mucosa and improving the voice quality in patients with vocal cord benign lesions.
