The Impact of Endoscopic Pituitary Surgery on Nasal Function
The Impact of Endoscopic Pituitary Surgery on Nasal Function
The aim of this study is to determine the impact of endoscopic transsphenoidal pituitary
 surgery on nasal function using a numerical simulation and to compare the difference between
 two kinds of transsphenoidal approachese(single nostril approach and bilateral nostril
 approach)．
Neuroendoscopic surgery is the first treatment for most pituitary adenoma patients. Because
 transsphenoidal surgery exploits the nasal corridor and paranasal sinuses to reach the skull
 base, sinonasal trauma is a primary source of postoperative morbidity in many of these
 patients. The aim of this study is to determine the impact of endoscopic transsphenoidal
 pituitary surgery on nasal function using a numerical simulation and to compare the
 difference between two kinds of transsphenoidal approachese(single nostril approach and
 bilateral nostril approach)．
