    Abstract:
    Recent advances in endoscopic sinus surgery suggested the potential for its surgical application to pituitary surgery. A number of institutions have reported the advantage of endoscope use in pituitary surgery, which is now widely accepted, but approaches to the sella vary in the literature. We retrospectively studied sella approaches in endoscopic pituitary surgery as rhinologists. Subjects included 6 cases of pituitary adenoma and 2 cases of Rathke's cleft cyst. A both-nostril transnasal transsphenoidal approach, our standard technique, was used in 6 cases. This approach consisted of elevation of mucoperiosteal flaps, resection of the vomer and sphenoid anterior wall, and opening of the sellar floor. Elevated mucoperiosteal flaps were used to close of the sella after tumor resection. All tumors were removed and no significant postoperative complications occurred. We found the both-nostril transnasal approach to be easy and time-saving and provided surgeon with a broad surgical field necessary to treat large tumors and accidental cases. Postoperative observation of the sella was easy for wide opening of the anterior wall of the sphenoid sinus. In our experience with reoperation, we quickly accessed the sella and easily removed tumors in the second operation. Our technique therefore has an advance in treatment of recurrence. The both-nostril transnasal approach involves the same procedures as median drainage of the sphenoid sinus, so our technique may have advantages in preventing mucocele of the sphenoid sinus as a late complication of transsphenoidal surgery. The transnasal transsphenoidal approach via both nostrils is preferable rhinologically.
