The aim of this report is to describe the long-term hearing prognosis of the transmastoid trans-superior semicircular canal approach. Three patients with small petrous bone cholesteatoma of the supralabyrinthine type removed by partial removal of the superior semicircular canal (SSCC) were followed up for 13, 9, and 10 years, respectively. All patients showed good bone conduction hearing during the follow-up period without postoperative complications, including longstanding disequilibrium causing a reduction in the quality of life. As an approach to petrous bone cholesteatoma of supralabyrinthine type that occupies a small area medial to the SSCC, the transmastoid trans-superior semicircular canal approach is less invasive and is considered to be a recommended approach.
本报告旨在描述经乳突经上半规管入路的长期听力预后情况。3例经上半规管部分切除治疗的迷路上型小岩骨胆脂瘤患者，分别随访了13年、9年和10年。所有患者在随访期间均表现出良好的骨导听力，且无术后并发症，包括长期失衡导致生活质量下降。作为一种治疗位于上半规管内侧小面积迷路上型岩骨胆脂瘤的入路，经乳突经上半规管入路侵袭性较小，被认为是一种推荐的入路。
