引起骨壁广泛破坏的上颌窦胆固醇肉芽肿

Cholesterol granuloma of the maxillary antrum with extensively bony destruction

目的 :探讨上颌窦胆固醇肉芽肿的发病机制、诊断及治疗。方法 :报告引起上颌窦骨壁广泛破坏的胆固醇肉芽肿 1例 ,并复习有关文献。结果 :胆固醇肉芽肿是肉芽组织反应的一种特殊类型 ,好发于乳突及颞骨的气房 ,但发生于上颌窦者少见。结论 :此病的病因可能是上颌窦口阻塞 ,窦腔内出血或渗出致胆固醇在窦腔内或囊肿内沉积。确诊需依靠病理 。

Objective:To study the pathogenesis,diagnosis and treatment of cholesterol granuloma of the maxillary antrum. Method:A case,with extensive bony erosion in the maxillary walls,was reported in At the same time,the relating literatures were reviewed.Result:The cholesterol granuloma was a particular form of tissue reactions of granulation.It was common to find cholesterol granuloma in the mastoid antrum and air cells of the temporal bone.But it was very rare in paranasal sinuses. Conclusion:The pathogenesis is probably hemorrhage of filtration as obstruction in the ostium providing favorable conditions for cholesterol to become precipited in the maxillary walls of cystis walls.The final diagnosis depend on pathologic examination.Establishing long-term ventilation between ostium and nasal meatus can cure this disease.
