Background Anterior glottic web is one type of laryngeal stenosis. Previous surgical methods had some drawbacks, such as large surgical trauma, long postoperative recovery time, and multiple-stage surgery. This study aimed to explore better treatment to repair anterior glottis web. Methods We performed vocal cord mucosal flap procedure on 32 patients with anterior laryngeal webs. All subjects received vocal cord scar releasing and vocal cord mucosal flap repair and suture under general anesthesia with self-retaining laryngoscope. Results All 32 patients completed surgery in one stage, without postoperative laryngeal edema, difficulty in breathing, or other complications. After the surgery, the anterior commissure of vocal cords recovered to a decent triangle shape in 28 patients; however, in four patients there were 2 to 3 mm adhesion residuals on the anterior ends of the vocal cords, accompanied by scar appearance of bilateral vocal cords. The GRB score, voice handicap index scores, and maximum phonation time score significantly improved in all patients after the surgery. There was no evidence of recurrent laryngeal webbing in the 6-month follow-up. Conclusion Vocal cords mucosal flap repair surgery has the advantages of less trauma, quick recovery, and significant improvement of the voice in the treatment of laryngeal webs.
