Nasosinus mucoceles: Our experiences at a tertiary care teaching hospital of Eastern India

Abstract

Background: Nasosinus mucoceles are expansile cystic masses originating at the paranasal sinuses by chronic retention of the mucus in a sinus cavity due to ostial obstruction. Aim: This study aims to evaluate the risk factors, clinical presentations, and management of nasosinus mucoceles. Materials and Methods: This is a retrospective study carried out over 5 years from August 2017 to September 2022 at a tertiary care teaching hospital. The diagnosis of nasosinus mucoceles was done by the clinical presentations and imaging of the paranasal sinuses. Results: There were 38 cases of nasosinus mucoceles included in the study. This study included 20 males and 18 females and male-to-female ratio of 1.11:1, with a mean age of 52.6 years (age range from 16 to 78 years). Computed tomography (CT) scan and magnetic resonance imaging were the main imaging done among study patients. All patients underwent endoscopic sinus surgery with marsupialization. Out of 38 patients, 2 (5.26%) had recurrence during the follow-up period. Conclusion: Orbital symptoms were major manifestations found in this study. CT scan was an important imaging performed in preoperative assessment. Endoscopic endonasal surgery is currently the gold standard for the treatment of nasosinus mucoceles. A satisfactory outcome was achieved after endonasal endoscopic marsupialization.
