Abstract

|
Background and Objectives : This study investigated the quality of life improvement after Surederm® implantation laryngoplasty in patients with adhesive true vocal cord.
Subjects and Method : A prospective study was conducted in 18 patients with adhesive vocal cord who underwent laryngoplasty using Surederm®. The exploration of adhesive lesions or lamina propria through the fenestration allowed for the creation of a pocket for Surederm® implantation within the intermediate layer of the lamina propria. Analyzed were the preoperative and postoperative parameters including the Korean-Voice Handicap Index, jitter, shimmer, noise to harmonic ratio, maximum phonation time and mucosal waves in stroboscopic findings.
Results: During the follow-up time of 12 months, the patients demonstrated excellent long-term vocal fold augmentation and significant improvement in all parameters measured. There is improved pliability of the vocal fold with good oscillation in all patients.
Conclusion: According to these results, it is suggested that Acellular Dermal Graft (Sure-derm®) implantation laryngoplasty can be a stable and effective surgical treatment for adhesive true vocal cord.
