Background: To demonstrate the efficacy of a new laser surgical technique for bilateral vocal fold immobility (BVFI) on postoperative quality of voice and swallowing.
Methods: Prospective study in a tertiary university hospital and a private hospital. Patients with iatrogenic BVFI were included. Outcome measures were Voice Handicap Index 10, 10-item Eating Assessment Tool, flexible laryngoscopy, and success of decannulation.
Results: Forty patients with post thyroidectomy BVFI were initially enrolled in our study; only 12 patients returned questionnaires and kept their follow-ups and were included in the study. All patients were successfully decannulated and remain decannulated up to 24-month follow-up. There was a statistically significant improvement in quality of swallowing and no significant deterioration in quality of voice. There was no need for revision up to 24-month follow up.
Conclusions: The "Π" technique using diode laser technology is a new and safe technique for BVFI with excellent long-term decannulation rates and improvement in quality of life and swallowing without significant changes in voice quality.
