Modified nasal septum root mucoperiosteum incision of pituitary adenomas via endonasal transsphenoidal approach

Abstract

Objective To explore the modified nasal septum root mucoperiosteum incision of pituitary adenomas via endonasal transsphenoidal approach, and reduce the incision-related postoperative complications as rhinorrhagia, septumperforation and dysosmia. Methods Sixteen patients with pituitary adenomas, admitted to and underwent modified nasal septum root mucoperiosteum incision of pituitary adenomas via endonasal transsphenoidal approach in our hospital from January 2013 and June 2013, were chosen in our study. The postoperative nasal complications were observed. The clinical data of them were analyzed retrospectively. Results Of all the 16 patients, total or subtotal removal rate was 93.8%. Rhinorrhagia or septumperforation did not appear. Dysosmia was not appeared in 15 patients with normal olfactory function; one patient had preoperative olfactory dysfunction, without getting worsen three months after surgery. Conclusion The reformative nasoseptal root mucoperiosteum incision of transsphenoidal surgery for pituitary adenomas can maintain the integrality of sphenopalatine artery and nasoseptal olfactory mucosa, and decrease the incidence of postoperative nasal complications, such as rhinorrhagia, septumperforation and dysosmia.
