The effect of maxillary sinus irrigation on early prognostic factors after endoscopic sinus surgery: a preliminary study.

Background: Sinus irrigation has been used to treat chronic rhinosinusitis refractory to medical and surgical treatments. The aim of this study was to evaluate the effect of maxillary sinus saline irrigation on the prevention of purulent rhinorrhea, extensive granulation formation, and polyp recurrence after endoscopic sinus surgery (ESS).

Methods: This prospective, controlled study was approved by the Institutional Review Board of Gachon University Gil Medical Center.

Effect of endoscopic marsupialization of paranasal sinus mucoceles involving the orbit: a review of 27 cases.

Paranasal sinus mucoceles (PSMs) can involve the orbit because the topographic anatomies of the paranasal sinuses and orbit are interrelated. We encountered 27 patients with PSMs involving the orbit that caused orbital symptoms. In this study, we evaluated the frequent symptoms and signs of PSMs involving the orbit, and report postoperative changes of orbital symptoms including the effects on visual acuity.
