Objective:
To describe a modified flap technique (MFT) involving the use of a false vocal fold flap for glottic reconstruction and the removal of arytenoid cartilage and to compare it with conventional frontolateral partial laryngectomy (FLPL) and laser cordectomy (LC).
Methods:
Twenty-eight MFT, 13 FLPL and 12 LC patients completed a standardised questionnaire for assessing aspiration, respiration, quality of life, and subjective voice quality. We analysed vocal function in terms of roughness, breathiness and hoarseness, measured voice range profiles, and performed videoendoscopy.
Results:
No patient reported respiratory problems. Aspiration occurred in 33.3% (MFT), 41.6% (FLPL) and 16.6% (LC). Voice quality was rated as good/satisfactory by 17 MFT patients (62%), satisfactory/sufficient by 69% of FLKT patients, and sufficient/poor by 75% of LC patients.
Conclusions:
The modified false vocal fold flap effectively covers defects and creates a neocord that ensures good phonatory rehabilitation and has positive effects on postoperative quality of life.
