| Summary: | Objectives: To assess vocal quality in patients undergoing transoral laser microsurgery (TLM) of the larynx with CO2 laser according to the type of cordectomy.
Study Design: Cross-sectional observational study.
Methods: Patients who underwent TLM for glottic squamous cell carcinoma (SCC) were divided into Group A (type III cordectomy) and Group B (types IV-V). The following parameters were assessed: fundamental frequency (F0), jitter, shimmer, maximum phonation time (MPT), GRBAS scale, and Voice Handicap Index-10 (VHI-10).
Results: Sixteen patients were enrolled, 8 in Group A and 8 in Group B. Patients in Group B had a higher VHI-10 compared to those in Group A. The values of G (grade), R (roughness), and S (strain), as well as acoustic parameters, were generally worse in Group B.
Conclusion: The type of TLM has a long-term impact on vocal quality, with a significant effect on quality of life.
