Otosclerosis very often leads to severe hearing loss in a chronic progressive manner. In the first phase of the disease, otospongiosis causes an inflammatory osteolytic process in the osseous labyrinthine capsule. In the cases reported here, this osteolytic process was pronounced in the osseous capsule of the cochlea. High-resolution CT and MRI showed the precise localization and stage of this inflammatory-osteolytic process in the petrous bone, while scintigraphy confirmed the diagnosis.
耳硬化症常常以慢性进行性方式导致严重听力损失。在疾病的第一阶段，耳海绵化在骨迷路囊内引发炎症性骨质溶解过程。在本文报道的病例中，这种骨质溶解过程在耳蜗的骨囊中较为明显。高分辨率CT和MRI显示了岩骨中这种炎症性骨质溶解过程的精确位置和阶段，而闪烁扫描术则证实了诊断。
