Cholesterol granuloma is a foreign body reaction to the deposition of cholesterol crystals, usually found in association to chronic middle ear diseases, being highly uncommon in the paranasal sinuses. Furthermore, a huge and aggressive cholesterol granuloma involving the maxillary sinus, hard palate, buccal space, and maxillary alveolus is extremely rare and has not been reported previously. This article reports a case of huge cholesterol granuloma in the maxillary sinus confused with an expansile odontogenic keratocyst, which was treated successfully via transnasal endoscopic approach.
胆固醇肉芽肿是对胆固醇结晶沉积的一种异物反应，通常与慢性中耳疾病相关，在鼻窦中极为罕见。此外，累及上颌窦、硬腭、颊间隙和上颌牙槽的巨大侵袭性胆固醇肉芽肿极为罕见，此前未见报道。本文报告一例上颌窦巨大胆固醇肉芽肿，误诊为膨胀性牙源性角化囊肿，经鼻内镜手术成功治疗。
