Minimally invasive endoscopic approach towards management of frontoethmoidal mucocoele with lateral displacement of eyeball and proptosis - A case report

Abstract

Rationale: Mucocoeles of paranasal sinuses are expansile and destructive lesions which can present with a variety of symptoms. If not treated early, they may lead to various complications. Patient Concerns: This report presents a case of a 26-year-old male patient with complaints of swelling of the left eye and double vision for 18 months. Diagnosis: Diagnosis of frontoethmoidal mucocoele with an unusual presentation of lateral displacement of the eyeball and proptosis was made based on patient history, clinical examination, and computed tomography. Treatment: The case was managed conservatively with marsupialization of the mucocoele using the transnasal endoscopic approach. Outcome: Complete resolution of the Mucocoele and its associated symptoms was observed, and frontal sinus ostium was found to be patent and completely epithelialized in 12-month follow-up. Take-away Lessons: The endoscopic approach toward the management of frontoethmoidal mucocoele is an effective alternative to conventional surgery with less patient morbidity and mortality.
