Abstract

Background: Voice outcome after carbon dioxide transoral laser microsurgery (CO2TOLMS) for glottic cancer is of prime importance. However, a comprehensive overview according to the European Laryngological Society (ELS) classification of cordectomies is still lacking. The aim of this systematic review is to summarize data on voice outcome associated with individual types of ELS glottic cordectomy after CO2TOLMS. Materials and Methods: A systematic review of the literature was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. The initial search identified 936 records of which 25 publications were then included. Voice outcome data (Voice Handicap Index [VHI] version 30, grade of dysphonia [G] and maximum phonation time [MPT]) were extracted per resection type. Weighted averages were calculated. Results: Data show a gradual increase in the VHI scores although they were still similar for all cordectomy types (range 14.2 to 21.5). The grade of dysphonia showed a gradual increase with increasing resection depth (range 1.0 to 1.9). There was a gradual decrease in the MPT (range 15.2 to 7.2). Conclusion: Voice outcome is related to cordectomy type with mild dysphonia characterizing ELS type I, II and III cordectomies, while more extended cordectomies (ELS type IV, V and VI) result in moderate dysphonia and shortness of breath during phonation.
