ObjectiveTo evaluate the feasibility of Transoral Videolaryngoscopic Surgery (TOVS) for radiorecurrent supraglottic and hypopharyngeal cancer, and to compare survival and complications between primary and radiorecurrent cases.MethodsTwelve cases of salvage TOVS for radiorecurrent cancer and 53 cases of TOVS as an initial treatment (primary cases) were evaluated. Days to resume soft diet, Functional Outcomes of Swallowing Scale (FOSS), postoperative complications, epithelization days and survival outcomes were assessed by retrospective chart review.ResultsFOSS score was significantly worse in salvage cases compared with primary cases. Bleeding and airway compromise was slightly greater in salvage cases than in primary cases; however, this was not statistically significant. Wound healing was significantly delayed in salvage cases compared with primary cases (P<0.001). In primary cases, wounds were re-epithelized within 60 days in 83% of patients and within 90 days in almost all patients, while in salvage cases 42% of patients required more than 90 days for wound healing. In salvage cases, the 5-year overall survival, disease specific survival rate, local control rate, and laryngeal preservation rate was 85.7%, 85.7%, 62.5%, and 78.0%, respectively, and 85.7%, 98.0%, 91.3%, and 97.8%, respectively, for primary cases. Local control rate was significantly better in primary cases than in salvage cases.ConclusionSalvage TOVS was feasible in highly selected cases. After serial transoral surgery, the final laryngeal preservation rate was satisfactory. Swallowing function in salvage cases tended to be worse than in primary cases, and a significantly longer time was required for wound healing.
