Abstract

With the development of minimally invasive endoscopic surgery and image-guided navigation systems, the endoscopic endonasal approach to petrous apex lesions has become more favorable. In this case, a petrous apex cholesterol granuloma was successfully treated with an endoscopic endonasal transpterygoid approach. A navigation system was used, and a contralateral nasoseptal flap and silicone tube stent were applied to maintain the cholesterol granuloma drainage pathway. The authors describe the endoscopic endonasal transpterygoid approach using a pedicled nasoseptal flap for petrous apex cholesterol granuloma and provide an intraoperative video and a literature review.
