반복된 삼출성 중이염 환자에서 발견된 이관 지방종 1예

Abstract

In the case of unilateral recurrent otitis media with effusion in adults, endoscopic examination of the nasopharyngeal tumor is necessary. Rarely, tumors can also develop in the eustachian tube. The incidence of lipoma in the eustachian tube is very rare. Lipomas are benign tumors arising from mesenchymal tissue and composed of well-differentiated adipocytes. A 49-year-old female patient visited for nasal congestion. But she had history of repetitive ventilation tube insertion due to recurrent otitis media with effusion. A yellowish round mass was noted at left eustachian tube orifice under nasal endoscopic exam. It was removed through intranasal access using sinus endoscopy. About 1 year after the surgery, there were no recurrence of tumor and middle ear effusion.
