The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.
