Oncological and Surgical Outcomes of Patients Treated by Transoral CO

To investigate the feasibility and the outcomes of transoral laser CO Retrospective chart review of patients treated by TLM cordectomy in a single European University Hospital for early-stage vocal fold SCCs (Tis, T1a, T1b, and T2). The following TLM outcomes were studied regarding the tumor size (Tis and T1a vs T1b and T2) and the margin status (negative vs positive/suspicious): patient position; type of laryngoscope; requirement to external counter pressure; resection of supraglottic structures (eg, ventricular band, epiglottic petiole, and suprahyoid epiglottis); pre- and postoperative complications; overall survival; disease-specific survival (DSS); and disease-free survival (DFS). A total of 148 patients were included. The TLM was realized in 95.3% of cases. External counter pressure, partial, or total vestibulectomy were necessary in 65.9%, 57.4%, and 4.2% of cases, respectively. A resection of the epiglottic petiole was required in 24.8% of cases. The realization of both epiglottis petiole resection and vestibulectomies were significantly higher in patients with T2 and T1b SCCs compared to those with T1a and Tis SCCs ( The exposure of glottis is possible in 95% of cases of early-stage vocal cord SCC but requires the use of several additional surgical procedures, especially for anterior commissure SCCs. The SCC involvement of the vocal fold anterior commissure is associated with lower DSS, DFS, and laryngeal preservation rate.
