Endoscopic image-guided transethmoid pituitary surgery.
OBJECTIVE
We describe a new endoscopic transethmoid approach for pituitary surgery and to compare it with other surgical techniques.


METHODS
Eleven patients undergoing pituitary surgery from September 2000 through January 2002 underwent an image-guided endoscopic transethmoid procedure to remove pituitary tumors. Ease of approach, resection, exposure of the surgical field, and operative complications were documented.


RESULTS
Endoscopic ethmoidectomy permits enhanced exposure and simplified tumor resection. The use of one nostril to stabilize the endoscope and the other to pass instruments affords a bimanual procedure that avoids the difficulty of small nares and keeping the scope fixed while exchanging instruments. Operative morbidity was low with no significant complications in this pilot study.


CONCLUSIONS
This approach opens a generous operative exposure while safely allowing room to endoscopically maneuver and affords direct access should revision surgery be needed.


CONCLUSIONS
This procedure uses a technique familiar to otolaryngologists and may be used for pituitary and other skull base tumors.
