Abstract
INTRODUCTION
We compare long-term voice outcomes in patients treated with European Laryngeal Society (ELS) classification Type I, Type II, or Type V cordectomy. The aim is to understand the impact of Type V cordectomy on voice outcomes in relation to Type I and Type II cordectomy.
METHODS
A retrospective review of patients treated with Type I, Type II, or Type V cordectomy by a single surgeon over a 20-year period was performed. Voice Handicap Index-10 (VHI-10) scores, Cepstral Spectral Index of Dysphonia (CSID) measures from CAPE-V sentences, and two-rater GRBAS scores were analyzed.
RESULTS
Sixty-two patients were identified with a mean follow-up of 52 months. Of these, there were 43 Type I and 19 Type II cordectomies, including 8 in each group with Type V resections. Significant differences in all parameters were noted between the Type I (VHI 5.7, CSID 20.6, Grade 1.3) and the Type II cohorts (VHI 12.6, CSID 36.3, Grade 1.8) who did not undergo Type V cordectomy. Patients undergoing Type V cordectomy demonstrated voice outcomes (VHI 9.4, CSID 35.6, Grade 1.7) which fell between those of Type I and Type II cordectomies.
CONCLUSIONS
Better long-term subjective, objective, and computer-analyzed voice outcomes are noted for patients undergoing Type I rather than Type II cordectomy. When Type V cordectomy is performed, voice outcomes are comparable to those of both Type I and Type II cordectomy, a surprising finding given the expectation of worsened dysphonia in longer resections. Further work is needed to explain this finding and define voice outcomes after Type V cordectomy.
