BACKGROUND Cholesterol granulomas of the petrous apex may impinge surrounding cranial nerves, leading to neurological impairments such as hearing loss. Less invasive endoscopic techniques are gaining popularity as the mainstay of therapy for this lesion. CASE REPORT We present a case of petrous apex cholesterol granuloma causing mild sensorineural hearing loss. An endoscopic endonasal transsphenoidal approach was successfully performed to partially resect and aerate the lesion. The auditory function on the affected side was completely restored after surgery. The patient experienced no post-operative complications. CONCLUSIONS This case report highlights the advantages of using an endoscopic transsphenoidal surgical approach in cases of petrous apex cholesterol granuloma, including the potential for this less invasive technique to restore sensorineural hearing loss.
背景 岩尖胆固醇肉芽肿可能压迫周围颅神经，导致诸如听力丧失等神经功能障碍。作为这种病变的主要治疗方法，侵入性较小的内镜技术正越来越受欢迎。病例报告 我们报告一例导致轻度感音神经性听力丧失的岩尖胆固醇肉芽肿病例。成功实施了内镜下经鼻蝶窦入路，部分切除病变并使其通气。术后患侧听觉功能完全恢复。患者未出现术后并发症。结论 本病例报告突出了在内镜下经蝶窦手术治疗岩尖胆固醇肉芽肿病例中的优势，包括这种侵入性较小的技术有可能恢复感音神经性听力丧失。
