%X <B>OBJECTIVE: </B>To analyze oncological and functional results of transoral minimally invasive surgery (TMIS) for supraglottic laryngeal carcinoma (SGLC), and investigate independent prognostic factors.<BR><B>METHODS: </B>Seventy SGLC patients treated with TMIS were included. The overall survival (OS), recurrence-free survival (RFS), and postoperative functions were analyzed.<BR><B>RESULTS: </B>Sixty-two patients were early-stage (Tis, T1, and T2) and eight patients were T3. Eleven patients received preoperative induction chemotherapy (IC). Sixty patients received transoral laser microsurgery (TLM), and 10 patients received transoral robotic surgery (TORS). Fifty-eight patients were scored Grade-1 by water swallow test, and 49 patients were scored Grade 0 by grade, roughness, breathiness, asthenia, strain. The 1, 3, and 5 year OS of all were 95.450%, 84.877%, and 78.026%, and RFS were 89.167%, 78.052%, and 75.451% respectively. Kaplan-Meier survival analysis showed N stage and clinical stage were associated with OS, smoking, clinical stage, surgical margins, and Ki-67 index were associated with RFS. There were no significant differences in preoperative IC or direct surgery, TLM, or TORS. Cox analyses showed smoking and surgical margins were independent prognosis factors for RFS.<BR><B>CONCLUSIONS: </B>The positive margin, Ki-67 index ≥40% and P53(+)&Ki-67 index ≥40% are worse factors affecting recurrence for SGLC patients. Both smoking and surgical margins are independent prognostic factors affecting recurrence.
