Objectives: Endoscopic transnasal transsphenoidal surgery has become the standard procedure for the majority of skull base diseases, including sellar, parasellar, and clival pathologies. The aim of this study was the objective evaluation of nasal airflow resistances and olfactory function in 3-dimensional (3D) endoscopic transnasal transsphenoidal surgery. Methods: One hundred patients who underwent 3D transnasal endoscopic surgery for sellar, parasellar, and clival diseases were enrolled. Active anterior rhinomanometry and Sniffin’ Sticks tests were performed before endoscopic surgery and at 3 and 6 months postoperatively. Results: No significant difference about nasal airflow resistance and olfactory function was observed between preoperative and postoperative subjective and objective scores. In the group of patients with sellar and parasellar diseases, a worst nasal respiratory function was seen when crusting was present, and a worst olfactory function was observed in patients with synechiae. Nasal functions returned to previous levels when crusting or synechiae solved. No statistically significant correlation was observed between the evaluated nasal functions and the reconstruction with flaps. Conclusions: The 3D endoscopic transnasal transsphenoidal surgery represents a more and more important tool in skull base surgery. It does not determine nasal respiratory and olfactory alterations after the treatment, without an increase in nasal complaints that could worsen quality of life.

Abstract
Objectives: Endoscopic transnasal transsphenoidal surgery has become the standard procedure for the majority of skull base diseases, including sellar, parasellar, and clival pathologies. The aim of this study was the objective evaluation of nasal airflow resistances and olfactory function in 3-dimensional (3D) endoscopic transnasal transsphenoidal surgery. Methods: One hundred patients who underwent 3D transnasal endoscopic surgery for sellar, parasellar, and clival diseases were enrolled. Active anterior rhinomanometry and Sniffin’ Sticks tests were performed before endoscopic surgery and at 3 and 6 months postoperatively. Results: No significant difference about nasal airflow resistance and olfactory function was observed between preoperative and postoperative subjective and objective scores. In the group of patients with sellar and parasellar diseases, a worst nasal respiratory function was seen when crusting was present, and a worst olfactory function was observed in patients with synechiae. Nasal functions returned to previous levels when crusting or synechiae solved. No statistically significant correlation was observed between the evaluated nasal functions and the reconstruction with flaps. Conclusions: The 3D endoscopic transnasal transsphenoidal surgery represents a more and more important tool in skull base surgery. It does not determine nasal respiratory and olfactory alterations after the treatment, without an increase in nasal complaints that could worsen quality of life.
