颞骨岩部胆脂瘤的临床诊断与治疗

Diagnosis and management of Petrous Bone Cholesteatoma

颞骨岩部胆脂瘤是临床上的少见病,其围绕迷路,缓慢生长。临床症状主要有听力下降、面瘫、眩晕等,与颞骨其他疾病的症状相似,无特异性,容易误诊误治。随着影像手段及显微外科技术的逐步发展,岩部胆脂瘤的早期诊断及手术治疗方法逐步改进。本研究主要回顾了国内外近年岩部胆脂瘤的相关文献,结合我们诊治的病例,总结岩部胆脂瘤的病因分类、诊断及鉴别诊断,对岩部胆脂瘤的分型与手术入路的选择等进行分析总结,为临床进一步优化治疗方案、选择适合的手术方式,提高病人生存质量提供参考。

Petrous bone cholesteatoma is a rare clinical disease. It grows around the labyrinth very slowly. It has the similar clinical symptoms with other temporal bone diseases such as：hearing loss, facial palsy, and vertigo. so itcan be easily misdiagnosed. With the development of imaging technology and microsurgery techniques, significant progress has been made in the diagnosis and treatment of petrous bone cholesteatoma. This research mainly reviews literatures on petrous bone choles-teatoma in recent years, with a summary on the methods of its diagnosis and differential diagnosis, PBC classification, choice of surgical approach, optimal treatment scheme, and selection of suitable operative methods. In the end, we hope to provide an optimized therapeutic approach to improve patient’s quality of life.
