Bi-nostril transseptal endoscopic approach to the sphenoidal gate. A new technique.

Abstract

There are multiple approaches to reach the sellar region using microscope or endoscope, which are the old sublabial, with its post-operative morbidities, or the uni-nostril transseptal, which has a limited working field. Another technique is the direct transnasal, which is associated with tissue sacrifice, and lastly the bi-nostril (one side transseptal-other side transnasal), aiming to preserve one of the septal flaps. We have 27 case studies using a new technique in which we access the sphenoid endoscopicaly through the nasal septum from both nostrils under the mucoperichondrial-periosteal flap. This new technique provides easy way of wide exposure to the sphenoidal gate, with easier closure of the operative field.
