Transoral robotic-assisted supracricoid partial laryngectomy with cricohyoidoepiglottopexy: Procedure development and outcomes of initial cases.

Abstract

We report on the feasibility and functional outcome of transoral robotic (TORS) supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP). Cadaveric studies and functional outcome at 3 years using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-H&N35), the Functional Outcome Swallowing Scale (FOSS), the Performance Status Scale for Head and Neck Cancer (PSS-HN), computerized voice analysis, and videotape recordings. Data were compared with a historical cohort of open CHEPs/cricohyoidopexies (CHPs). The EORTC-QLQ-H&N35 scores, FOSS scores, and PSS-HN scores at 3 years of 2 operated patients were 46 and 43, 2 and 1, and 75 of 100 (eating in public) and 100 of 100 (normalcy of diet), respectively. The mean fundamental frequency, jitter, shimmer, noise-to-harmonic ratio (NHR), and maximum phonation time (MPT) were 85 HZ and 81 Hz, 8.52% and 6.39%, 28.2% and 13.5%, 0.61 and 0.71, 19 seconds and 15 seconds, respectively. Functional outcome data suggest that the procedure is feasible and safe.
