介绍了两例单侧骨化性迷路炎合并双侧慢性化脓性中耳炎的组织病理学。在这两种情况下，骨化和纤维化仅限于下基底转的鼓阶，显然是由于炎症通过圆窗膜进入所致。圆窗被新骨和纤维组织堵塞，除了中耳病变导致的传导性听力损失之外，可能还会导致传导性听力损失。柯蒂氏器毛细胞的变性仅限于发生骨化和纤维化的下基底转。
Histopathology of two cases of unilateral labyrinthitis ossificans in the presence of bilateral chronic suppurative otitis media is presented. In both cases, ossification and fibrosis were limited to the scala tympani of the lower basal turn, apparently due to inflammation entering through the round window membrane. The round window was occluded by new bone and fibrous tissue presumably resulting in a conductive hearing loss in addition to the conductive loss due to middle ear lesions. Degeneration of the hair cells of the organ of Corti was limited to the lower basal turn where ossification and fibrosis occurred.
