Labyrinthitis ossificans is fibrosis or ossification of the membranous labyrinth. Tympanogenic, meningogenic, and hematogenous etiologies are more common than trauma in the development of labyrinthitis ossificans. We present a case complaining of right-sided hearing loss and symptoms of otitis media and positional vertigo resulting from perilymphatic fistulization. Imaging revealed labyrinthitis ossificans secondary to temporal bone fracture crossing through the otic capsule.
耳硬化症是膜迷路的纤维化或骨化。在耳硬化症的发展过程中，与创伤相比，源于鼓室的、源于脑膜的和血源的病因更为常见。我们报告了一例因外淋巴瘘导致的右侧听力损失和中耳炎及位置性眩晕的病例。影像学显示颞骨骨折穿过骨迷路导致耳硬化症。
