Abstract：Objective To explore the method of transposition of sellar pedicled-mucoperiosteum flap for skull base reconstruction after endoscopic endonasal transsphenoidal surgery (EETS) and its value to the skull base reconstruction. Methods The clinical data of 23 patients who underwent skull base reconstruction by transposition of sellar pedicled-mucoperiosteum flap after EETS for the tumors or cysts from October, 2014 to January, 2016 were analyzed retrospectively. The size of sellar pedicled-mucoperiosteum flap was determined by neuro-navigator-assisted surgery and then semi-free sellar pedicled-mucoperiosteum flap was made by electrical drill and fractured down. After the resection of the tumors or cysts, the semi-free sellar pedicled-mucoperiosteum flaps were transpositioned, and fixed with fibrin glue. Results Of 23 patients, 1 had craniopharyngioma, 2 suprasellar Rathke cysts and 20 pituitary adenomas. The cerebrospinal fluid leakage happened intraoperatively in 3 patients, in whom the artificial material was used to repair the leakage and then the transposition of sellar pedicled-mucoperiosteum flap was performed. All the patients were followed up for 6 months. There were no cerebrospinal fluid leakage, bacterial meningitis, tension pneumocephalus and other complications in all the patients during the following-up. Conclusion The transposition of sellar pedicled-mucoperiosteum flap is a reliable, safe and effective method to reconstruct the skull base after EETS
