Abstract
Surgical techniques for the removal of vocal fold (VF) disorders that arise within the lamina propria must permit the preservation and/or restoration of VF vibratory characteristics. The endoscopic VF microflap is designed to do such. A retrospective study was undertaken to evaluate the efficacy of this procedure. Forty microflaps (7 bilateral, 1 revision) were performed on 32 patients. Charts and surgical pathology findings were reviewed. Preoperative and 3-month postoperative video recorded voice samples and stroboscopic examination results were compared. Findings on perceptual voice analysis did not significantly change. Stroboscopic examinations revealed improved postoperative VF closure in 27 of 29 patients with impaired preoperative closure and return of mucosal wave in 18 of 24 VFs operated on for the excision of cysts or polyps. When present preoperatively (6 patients), the mucosal wave was preserved. Most patients (28 of 30) rated themselves as clinically improved. The endoscopic VF microflap is efficacious in the treatment of selected VF disorders. The surgical technique is discussed.
