To investigate the indications, key point, advantages, and disadvantages of transmaxillary approach for microsurgical removal of clivus tumors.The clinical data of 16 consecutive patients with clivus tumors operated upon through transmaxillary approach, based on Le Fort I ostectomy, July 1999 to May 2002 were retrospectively reviewed.Of the 16 patients, 8 patients suffered from chordoma, 2 from angiofibroma, 1 from pituitary adenoma, 1 from chondroma, 1 from adenocarcinoma of grade II, 1 from mucoid cyst, 1 from myeloma, and 1 from fibrous dysplasia of bone. Four out of the 16 cases were with recurrent tumors after operation performed in other hospitals. The operation field of all 16 patients was satisfactorily exposed. The tumors of 10 cases were totally removed under microscope, and 6 tumors were subtotally removed. The complications included rhinorrhea in 1 case and malocclusion in 3 cases. There was no operative mortality. All patients were followed up for 6 approximately 40 months (ion average 20 months) with MRI. Four of them had local recurrence within 1 year, 1.5 years, 2 years, and 9 months respectively after operational and have lived with tumors till now. The remainders had resumed their normal life.An ideal approach, transmaxillary approach facilitates the resection of clivus tumors, with satisfying exposure and fewer complications.
