摘要：

目的探讨迷路骨化的临床特点及诊断方法。方法回顾性分析诊断的3例(3耳)慢性中耳炎并发迷路骨化患者的病历资料，分析其临床特点、CT及MRI影像学表现。结果 3例均发生于右耳，均存在耳蜗、半规管及前庭的骨化，CT表现为蜗管及半规管被致密的高密度影充填，MRI表现为内耳水成像不能显示迷路的各项解剖结构的特点。结论通过CT、MRI影像学检查，可以准确显示迷路骨化的病理特点，这也是确诊的主要手段。

Abstract:

Objective To explore the clinical features and diagnostic methods of labyrinthine ossification. Methods The retrospective analysis was conducted in 3 cases (3 ears) diagnosed as chronic otitis media complicated with labyrinthine ossification in our department from June 2009 to June 2011. Clinical characteristics, computed tomographic (CT) and magnetic resonance imaging (MRI) manifestations were discussed. Results Cochlea, semicircular canals and vestibule with ossification occurred in the right ears of the 3 patients. CT showed the cochlear duct and semi-regulatory tube were filled with high-density shadows, and MRI water imaging failed to show the structure of the labyrinth. Conclusion CT/MRI is an appropriate method for identification of labyrinthine ossification.
