Forty-two patients (84 ears) with surgically confirmed otosclerosis were examined with a computerized tomographic scanner (Philips Tomoscan 310) equipped with a table swivel mechanism. All ears were scanned in the horizontal and a new semilongitudinal plane. In patients with an unimpaired bone conduction threshold, a normal labyrinthine capsule was found in all ears except two. Normal bone conduction does not exclude extensive labyrinthine otospongiosis. In cases with bone conduction impairment, the bony labyrinth appeared normal in about half the ears. In the other half, areas of bone resorption were present and a positive correlation was found between the degree of bone loss and the amount of bone conduction threshold loss.
42例（84耳）经手术确诊为耳硬化症的患者，使用配备有台面旋转装置的计算机断层扫描仪（飞利浦Tomoscan 310）进行检查。所有耳朵均在水平位和一个新的半纵切面进行扫描。在骨传导阈值未受损的患者中，除两耳外，其余所有耳朵的迷路骨壁均正常。正常的骨传导并不排除广泛的迷路性耳海绵化症。在骨传导受损的病例中，约一半耳朵的骨迷路看起来正常。在另一半耳朵中，存在骨质吸收区域，并且发现骨质丢失程度与骨传导阈值丢失量之间呈正相关。
