OBJECTIVES/HYPOTHESIS: We present the case of a 21-year-old woman who underwent endoscopy-assisted surgery with topical mitomycin for a large cholesterol granuloma in the petrous apex that involved the eustachian tube.
Case report.
Minimally invasive surgery was performed on the cholesterol granuloma with endoscopic assistance, and topical mitomycin (0.4 mg/mL) was administered to prevent scarring of the newly created drainage/ventilation route. With the endoscopic approach, the drainage/ventilation route was secured not only from the tympanic cavity, but also using a guidewire inserted from the pharyngeal orifice of the eustachian tube.
The drainage/ventilation route between the nasopharynx and middle ear cavity involving the cholesterol granuloma has been preserved more than for 9 months postoperatively. Her hearing has recovered.
This less invasive technique is a surgical option for patients with a large cholesterol granuloma in the petrous apex involving the eustachian tube.
目的/假设：我们报告了一例 21 岁女性患者，她因岩尖的大胆固醇肉芽肿（累及咽鼓管）接受了内镜辅助下局部丝裂霉素手术。
病例报告。
在内镜辅助下对胆固醇肉芽肿进行微创手术，并局部应用丝裂霉素（0.4mg/mL）以防止新形成的引流/通气途径的瘢痕形成。通过内镜方法，不仅从鼓室，而且还使用从咽鼓管咽口插入的导丝来确保引流/通气途径。
术后 9 个月以上，保留下咽鼓管和中耳腔之间的涉及胆固醇肉芽肿的引流/通气途径。她的听力已恢复。
对于累及咽鼓管的岩尖大胆固醇肉芽肿患者，这种微创技术是一种手术选择。
