PURPOSE: This study prospectively assessed the efficacy and safety of532-nm diodelaserglottoplastyin patients with sulcus vocalis. METHODS: A prospective human trial was performed from August 2016 to September 2021.532-nm diode laserglottoplasty was performed in 30 consecutive patients with sulcus vocalis who suffered from voice problems. Patients underwent acoustic aerodynamic, perceptual, stroboscopic, and Voice Handicap Index-10 (VHI-10) evaluations before and 1, 6, and 12 months afterlaserglottoplasty. RESULTS: Most subjective parameters showed significant improvement (P < 0.05) at 6 monthsafter laserglottoplasty and remained stable at 12 months. Most objective parameters showed significant improvement (P < 0.05) at 12 months afterlaserglottoplasty.Complications during follow-up included mild vocal fold vibration reduction in 3.3% of patients (1/30) and persistent vocal fold edema in 3.3% of patients (1/30). CONCLUSIONS: Statistically significant voice improvement at 12 months after 532-nm diode laserglottoplasty was achieved without serious complications.
