안와이소를 동반한 전두사골동 점액 농류 1례

Abstract

Mucoceles or mucopyoceles of the paranasal sinus are slowly growing expansile benign cystic lesions as a result of obstruction of draining ostium with subsequent accumulation of mucoid secretion. A case of a huge frontoethmoidal mucopyocele that developed after previous intranasal surgery in a young woman is presented. The case was complicated by intracranial and intraorbital inflammatory extension, that result in headache and bizarre facial appearance due to severe orbital dystopia. CT and MRI were utilized as diagnostic tools. The mucopyocele was eradicated by external surgical approach and the resulting defect was partially reconstructed with frontalis-galeal myofascial flap Downwardly and lateral wardly displaced orbit was restored spontaneously to its original position and the patient shows no evidence of recurrence of the lesion in a 10-month follow up check. Functional endoscopic sinus surgery is now widely performed for treatment of most paranasal sinus mucoceles but external surgical approach should be considered in some selected cases that need secondary reconstructive procedure.
