Our clinical experience with reconstruction of the sellar floor during transnasal-transsphenoidal surgery for @entity977 using ceramics composed of a combination of @entity692 and @entity9039 (pituitary plate) is described. A pituitary plate was used to reconstruct the sellar floor in 15 @entity1 with @entity977 that included 13 @entity977 and 2 Rathke's @entity2419 . This method is indicated for cases of reoperation and cases in which there is of much cerebrospinal fluid leakage during surgery. This material is provided as a pituitary plate 12 x 12 mm round and 2 mm thick. There are four holes in the center by which the plate can be held with regular bipolar forceps. At the time of closing the sellar floor window, a pituitary plate was carved with scissors into a suitable shape and slipped inside the @entity154 . The postoperative position of the pituitary plate could be clearly identified on skull roentgenogram and magnetic resonance imaging. No displacement or migration of the implanted pituitary plate was observed in any @entity1 during follow-up radiological examinations. Infections such as a @entity733 or @entity693 were not observed clinically or radiologically in any @entity1 . In three @entity1 who underwent repeated transnasal surgery for regrowth of the @entity5 , the pituitary plate that had been placed at the initial procedure was covered with a thin fibrous capsule and the plate was well preserved. These results indicate that a pituitary plate can be useful for reconstruction of the sellar floor in transnasal-transsphenoidal surgery.
