摘要

額竇膽脂肉芽腫是一種相當罕見的疾病。它有典型的組織病理包括膽脂晶體、紅血球浸潤及其周圍的肉芽組織。其致病機轉，相信與出血、人體腔洞之通氣不良以及引流不佳有關。外科切除病灶及患部之腔竇保持良好的通氣引流狀況可將此病症治癒。由文獻上的報告，膽脂肉芽腫可由病史及電腦斷層掃描，核磁共振影像之檢查作術前鑑別診斷。本文報告1例外傷10年後併發巨大之額竇膽脂肉芽腫。我們以骨粘膜瓣重建法打開額竇將腫瘤完整摘除，並填以腹部脂肪，結果良好。

Cholesterol granuloma of the frontal sinus is a rare disease which has the characteristic pathology including granulomatous reaction surrounding cholesterol crystals and altered blood. Hemorrhage, disordered ventilation and impaired drainage are decisive pathogenic factors in the causation of cholesterol granuloma. Cholesterol granuloma of the frontal sinus is treated effectively through radical clearance or drainage of the sinus cavity. A review of the literature on cholesterol granuloma suggests that the early clinical manifestations and radiographic features, ie., high-resolution CT, MRI, allow for a critical preoperative differentiation. We present a case of huge cholesterol granuloma of the frontal sinus following a falling-down accident 10 years previously. The patient was treated by tumor extirpation through osteoplastic approach to the frontal sinus and fat obliteration with a good result.
