Sphenoidotomy kinetics in patients with chronic rhinosinusitis without nasal polyps.

Objective: Stenosed sphenoid sinus ostia are among the most common findings in revision endoscopic sinus surgery. This study sought to identify the optimal intraoperative sphenoidotomy size for prevention of postoperative stenosis.

Methods: 32 patients affected by chronic rhinosinusitis not associated with nasal polyps (CRSsNP) underwent 52 sphenoidotomies.
