Voice outcome after unilateral ELS type III or bilateral type II resections for T1-T2 glottic carcinoma: Results after 1 year.

BACKGROUND: Voice outcome was assessed in patients with extended T1 and limited T2 glottic carcinoma, treated with a unilateral type III or a bilateral type II resection according to the European Laryngological Society (ELS) classification. METHODS: Objective evaluation (acoustic and aerodynamic parameters), perceptual evaluation (GRBAS), and patients' self-assessment (voice handicap index [VHI]) were performed before and 1 year after treatment. Results were evaluated according to ELS resection type and the involvement of the anterior commissure. RESULTS: The majority of voice parameters in all resection subgroups showed an improvement of the mean score 1 year postoperatively. Grade of dysphonia varied between 1.15 and 1.66 postoperatively and VHI score varied from 23.3 to 24.5. CONCLUSION: Voice outcome after ELS unilateral type III or a bilateral type II resection for extended T1 and limited T2 glottic carcinoma is good with mild to very moderate perceptive dysphonia and low self-reported voice impairment.

Voice profile after type I or II laser chordectomies for T1a glottic carcinoma.

BACKGROUND: Can a "typical" voice in terms of auditory perception be defined after type I or II chordectomy? Do other parameters in a multidimensional voice protocol correlate to this perceptual profile? METHODS: Voice evaluation using a multidimensional voice protocol including perceptual (GRBAS; grade, roughness, breathiness, asthenia, strain scale), acoustic, aerodynamic, stroboscopic analyses, and self-assessment (Voice Handicap Index [VHI]) in a cohort of 37 consecutive patients with T1a midcord glottic carcinoma. RESULTS: Sixty-five percent of patients had dysphonia, dominated by mild breathiness (mean grade 1.4). Voice Handicap was minimal (mean VHI 19). Acoustic and aerodynamic parameters were only mildly deviant. The correlations between perceptual analysis and the other parameters were weak. CONCLUSION: The typical laser treated voice (type I or II resections) is characterized by mild breathiness in perceptual analysis. Correlations with other parameters, including patients' self assessment, are weak. Therefore, these outcomes do not form 1 integrated voice profile. This may have consequences for clinical decision-making.

Voice outcome in T1a midcord glottic carcinoma: laser surgery vs radiotherapy.

OBJECTIVE: To compare voice quality after radiotherapy or endoscopic laser surgery in patients with similar T1a midcord glottic carcinomas according to a validated multidimensional protocol. DESIGN: Retrospective cohort study. SETTING: University cancer referral center. PATIENTS: Two cohorts of consecutive patients willing to participate after treatment for primary T1a midcord glottic carcinoma with laser surgery (18 of 23 eligible) or radiotherapy (16 of 18 eligible). MAIN OUTCOME MEASURES: Posttreatment voice quality was evaluated according to a multidimensional voice protocol based on validated European Laryngological Society recommendations, including perceptual, acoustic, aerodynamic, and stroboscopic analyses, together with patient self-assessment using the Voice Handicap Index. RESULTS: Approximately half of the patients had mild to moderate voice dysfunction in the perceptual analysis (53% [8 of 15] in the radiotherapy group and 61% [11 of 18] in the laser surgery group) and on the Voice Handicap Index (44% [7 of 16] in the radiotherapy group and 56% [10 of 18] in the laser surgery group). The voice profile in the laser surgery group was mainly breathy; in the radiotherapy group, it was equally breathy and rough, with a trend for more jitter in the acoustic analysis. There was no statistical difference in the severity of voice dysfunction between the groups in any of the variables. CONCLUSIONS: Endoscopic laser surgery offers overall voice quality equivalent to that of radiotherapy for patients with T1a midcord glottic carcinoma, although specific voice profiles may ultimately be different for the 2 modalities. We believe that endoscopic laser surgery is the preferred treatment in these patients because it provides oncologic control similar to that of radiotherapy and the additional benefits of lower costs, shorter treatment time, and the possibility of successive procedures.
