Multidimensional Voice Quality Evaluation After Transoral CO 2 Laser Cordectomy: A Prospective Study

Abstract : Objective: To investigate voice quality changes of patients treated by transoral laser cordectomy (TLC) for early glottic cancer according to the type of cordectomies. Methods: A total of 164 consecutive male patients with an early glottic cancer were prospectively recruited from the Department of Otolaryngology—Head and Neck Surgery of the Georges Pompidou European Hospital. Depending on the tumor characteristics, patients benefited from type I to VI CO 2 cordectomy regarding the European Laryngological Society classification. The following voice quality outcomes were pre- to postoperatively assessed: voice handicap index (VHI), perceptual grade of dysphonia, roughness, breathiness, maximum phonation time, and acoustic parameters. Results: Fifty-five patients with Tis, T1, or T2 vocal fold cancer completed the study (mean age: 61.7 years). Of these patients, 34 and 21 composed group 1 (types I-III TLC) and group 2 (types IV-VI TLC), respectively. Voice handicap index, grade of dysphonia, and breathiness significantly improved from pre- to 3- and 6-month posttreatment in group 1. In group 2, only VHI significantly improved from pre- to 3- and 6-month posttreatment. Acoustic and aerodynamic measurements did not change throughout the postoperative course. Patients with types I to III TLC exhibited better postoperative voice outcomes compared to those treated by types IV to VI TLC. Conclusion: Irrespective to the types of TLC, the subjective voice quality of patients treated by CO 2 laser cordectomy for early glottic cancer significantly improved from pre- to 3- and 6-month posttreatment. The usefulness of aerodynamic and acoustic measurements as postoperative outcomes of voice quality changes remain controversial and require future studies considering multidimensional assessment of voice.
