Abstract
Trans-oral maxillectomy requires no facial incision and reduces deformity, thereby decreasing the psychological trauma of radical surgery. The duration of surgery is shortened drastically. En bloc maxillectomy and orbital exenteration is possible. Wound healing is better. The survival time of 222 patients with maxillectomy was investigated, and the prognosis was found to be better in patients treated by the trans-oral approach. The operative technique can easily be learned by anyone skilled in otorhinolaryngological surgery.
