This review focused on both the new diagnostic method for ossicular anomalies and the pathophysiology of otosclerosis and otosclerosis-related disorders.
First, this article demonstrated the advantages of virtual endoscopy imaging, and the application of 3D imaging for patients with ossicular anomalies. This technique may play an important role in preoperative planning and surgical training.
With regard to stapes surgery, recent knowledge of the clinical characteristics and temporal bone pathology in patients with otosclerosis-related diseases was described. The cause of both complications and residual conductive hearing loss after stapes surgery was also discussed by clinical investigations and by histopathologic study of temporal bone in patients with otosclerosis.
Key words : ossicular chain anomaly, 3D CT, otosclerosis, stapes surgery, temporal bone pathology
