We report a case of cholesterol granuloma of the petrous apex which was surgically treated via an endoscopic trans-sphenoidal approach.
Case report and review of the literature concerning cholesterol granulomas of the petrous apex and their management.
The lesion was approached endoscopically via a bilateral sphenoidotomy with removal of the vomer. A large cholesterol granuloma was evacuated and marsupialised. The patient made an uneventful recovery.
Trans-sphenoidal access to the petrous apex represents an alternative route for the drainage and ventilation of cholesterol granulomas. This approach is the technique of choice when the cholesterol granuloma abuts the posterior wall of the sphenoid sinus. The trans-sphenoid approach, unlike other lateral approaches to the petrous apex, spares cochlear and vestibular function and allows post-operative endoscopic follow up.
我们报告一例经内镜经蝶窦入路手术治疗的岩尖胆固醇肉芽肿病例。
病例报告及有关岩尖胆固醇肉芽肿及其治疗的文献综述。
通过双侧蝶窦切开术并切除犁骨，经内镜处理病变。一个大的胆固醇肉芽肿被清除并袋形缝合。患者恢复顺利。
经蝶窦入路处理岩尖为胆固醇肉芽肿的引流和通气提供了一种替代途径。当胆固醇肉芽肿紧邻蝶窦后壁时，此入路是首选技术。与其他处理岩尖的外侧入路不同，经蝶窦入路可保留耳蜗和前庭功能，并允许术后进行内镜随访。
