Abstract:
Postoperative cerebrospinal fluid (CSF) leaks still occur in patients without intraoperative CSF leaks after endoscopic endonasal pituitary adenoma surgery. We propose a reconstructive technique, the sellar floor flap (SFF), for universal sellar anatomical reconstruction. A total of 113 patients without intraoperative CSF leaks after endoscopic endonasal pituitary adenoma surgery from July 2013 to June 2016 were reviewed: 43 underwent sellar reconstruction with the SFF (the SFF group) and 70 underwent sellar packing only (the nonreconstruction group). No case of postoperative CSF leak was reported in the SFF group, whereas 7 cases were reported in the nonreconstruction group ( P < .05). The SFF is suitable for universal reconstruction after endoscopic endonasal pituitary adenoma surgery and may decrease postoperative CSF leak.
