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.
