  Background: Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects.

  Methods: In this prospective study, 43 patients with pituitary adenoma who were candidates for EETSA from March 2012 to October 2013 were enrolled. The patients were evaluated preoperatively using acoustic rhinometry and rhinomanometry (with/without the use of decongestant drops) and asked to complete the 22-Item Sino-nasal Outcome Test (SNOT-22) questionnaire.  The tests were repeated at one and three months postoperatively. The preoperative data were compared with the first and second postoperative ones using paired-sample t-test.

  Results: Without the use of decongestant drops, the total airway resistance increased significantly (p=0.016), and the nasal airflow decreased significantly (p=0.031) in the first postoperative evaluation. However, in the 3rd postoperative month, the difference was not significant. With the use of decongestant drops, the objective parameters showed no significant changes compared to preoperative data even at the first evaluation. The SNOT-22 scores also did not differ significantly in 1st and 3rd postoperative months. The first postoperative SNOT-22 showed a strong correlation with the second minimal cross-sectional area on simultaneous evaluation, and with the preoperative total airway resistance.

  Conclusion: EETSA has a transient adverse effect on the nasal patency that quickly improves, making it a safe approach for the sinonasal system. Rhinomanometry is the most sensitive test for detecting these nasal functional changes objectively.
