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

Abstract

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.

Quality of life and voice outcome of patients treated with transoral CO2 laser microsurgery for early glottic carcinoma (T1–T2): a 2-year follow-up study

“…This latter finding was consistent with our results, although no exact VHI scores were given in that study [30]. The difference in VHI improvement between males and females might be explained by the fact that women show postoperative fundamental frequencies within the normal female range, whereas male patients show postoperative fundamental frequencies that are higher than the normal male range (van Loon et al [18]). Potentially, this characteristic could lead male patients to experience a larger change in their voice and therefore to be less satisfied.…”

“…All patients with lesions that met these criteria were offered a treatment choice between TLM and radiotherapy. Patients made their choice after comprehensive counseling (described elsewhere in detail by van Loon et al [ 18 ]). After stroboscopy, the definite tumor stage was determined endoscopically under general anesthesia.…”

Voice Quality Outcomes After Transoral CO2 Laser Cordectomy: A Longitudinal Prospective Study

“…The auditory-perceptual voice quality evaluation is the most commonly used clinical voice assessment method and is reported as a useful outcome 1 year after type I-III TLC. 21 In the present study, the better overall improvement of voice quality of the type I-III group was supported by our perceptual analyses, which revealed significant reduction of GRBAS parameters in these patients. The usefulness of perceptual voice quality evaluations and their significant postoperative improvements in patients benefiting from type I-III TLC were noted by Chu et al and Galletti et al, respectively.…”

Evolution of voice after transoral laser cordectomy for precancerous lesions and early glottic cancer

“…Currently, most surgeons agree that measuring the extent of cordectomy is crucial in evaluating voice outcomes after a TLC [ 10 , 25 , 26 , 28 ]. We chose this approach in the present study.…”

“…Their patients underwent unilateral transmuscular (ELS type III) or bilateral subligamental (ELS type II) resections. The results of that study suggested that the majority of patients could expect to have mild to very moderate dysphonia 1 year postoperatively, based on ratings by experienced listeners and patient self-assessments [ 28 ].…”
