- Abstract
Objectives/Hypothesis: To compare the 12‐month evolution of voice quality outcomes in patients who benefited from types 1–2 transoral CO2 laser cordectomy (TLC) for an early‐stage vocal fold squamous cell carcinoma (VFSCC). Study Design: Prospective uncontrolled study. Methods: Sixty patients with cT1 VFSCC were consecutively recruited from a single medical center. Thirty patients benefited from type 1 TLC, while type 2 TCL was performed in 30 patients. The following voice quality outcomes were evaluated at baseline, 3‐, 6‐, and 12‐month post‐TLC: voice handicap index (VHI), GRBAS, speech rate, maximum phonation time (MPT), and acoustic parameters. Voice quality evolution was compared between type 1 and type 2 TLC. Results: Fifty‐seven patients completed the evaluations. Type 1 TLC patients reported significant improvements of VHI, grade of dysphonia, and breathiness at 3‐, 6‐, and 12‐month post‐TLC. Speech rate and jitter values improved 6‐ and 12‐month post‐TLC. A few voice quality outcomes reported 3‐ or 6‐month post‐TLC improvements in type 2 TLC group, while VHI, grade of dysphonia improved at 6‐ and 12‐month post‐TLC. MPT significantly decreased at 6‐ and 12‐month post‐TLC, while there were no acoustic measurement changes in type 2 TLC. Conclusions: The effect of TLC on voice quality may depend on the type of TLC. Type 1 TLC was associated with faster voice quality improvements compared with type 2 TLC. VHI and dysphonia grade were identified as the most relevant tool of voice changes irrespective to the TLC type. Level of Evidence: 3 Laryngoscope, 132:1421–1426, 2022
