BACKGROUND AND OBJECTIVE: To study the feasibility of a total endoscopic technique for selective neck dissection in @entity5 and to compare the technique with conventional open technique with a long cervical scar. METHODS: We included @entity1 with early intraorally resectable @entity957 and excluded @entity1 whose @entity75 required reconstruction with microvascular flaps. We compared the following intraoperative parameters: cumulative length of the incision(s), duration of surgery, estimated @entity190 , and intraoperative complications. The postoperative parameters included hospital stay, shoulder function, duration of analgesic use, and early @entity260 . We used Shoulder @entity158 And Disability Index scores to assess shoulder function and assessed the oncologic outcome histopathologically by the number of nodes dissected. RESULTS: The mean operative time for minimally invasive supraomohyoid neck dissection (MISOND) was 53.7      29.8  min, which was significantly longer than 39.4      5.0  min for the open technique. The estimated @entity190 in the MISOND group was significantly lower compared with the open technique (p  <  0.001), and there were no major intraoperative complications in either group. Postoperative recovery assessed by hospital stay and time to resume routine work was slightly shorter in the MISOND group but not statistically significant. There were no reported early @entity260 such as @entity548 , wound dehiscence, or chyle leakage in either group. The mean Shoulder @entity158 And Disability Index score assessed 2  weeks postoperatively for the MISOND group was 14.35      0.71  %, which was significantly better than 44.14      1.18  % for the open technique (p  <  0.001). The number of nodes dissected showed no significant difference between groups. CONCLUSIONS: MISOND is a feasible and safe procedure with immediate oncologic outcomes comparable with those of conventional open SOND and provides better cosmetic and functional outcomes.
