OBJECTIVE: The pulsed dye laser (PDL) has been shown to be effective in the treatment of hypertrophic scars and keloids in dermatology. On the basis of histopathologic similarities between sulcus vocalis and scar tissue and numerous reports on the treatment of laryngeal lesions, especially scar tissue, with PDL, we evaluated the efficacy of treating sulcus vocalis with PDL. We named this surgical procedure PDL glottoplasty. STUDY DESIGN: Case series with planned data collection. SETTING: A university-based, tertiary care medical center. SUBJECTS AND METHODS: This study was conducted on 25 patients diagnosed with sulcus vocalis by videostroboscopy at the Gangnam Severance Hospital Otorhinolaryngology Department between August 2006 and February 2012. Energy delivery was fixed at 0.75 Joules (J) per pulse, and each vocal fold was administered 60 to 110 pulses (average 72.5 pulses) during each procedure. Aerodynamic, stroboscopic, and acoustic voice analyses were performed pre- and postoperatively. RESULTS: Although assessment was necessarily subjective, our study indicated that vocal folds showed decreased stiffness and improved mucosal wave properties after treatment, resulting in improved vibration and dysphonia. In the objective assessments, most patients who underwent PDL glottoplasty showed improvement in several postoperative voice analysis indices. The differences between preoperative and some postoperative voice parameter indices were statistically significant. CONCLUSION: We found PDL glottoplasty to be beneficial in the treatment of sulcus vocalis. Objective measurements of voice quality and normalization of vocal fold vibration improved after PDL treatment in most cases. Our results warrant further studies with larger numbers of participants and longer follow-up periods.
