Unilateral isolated incus agenesis: detection by virtual endoscopy.

摘要

We report the first case of unilateral incus agenesis in the literature. Preoperative diagnosis by virtual endoscopy further enhances the significance of this case. We present thin-section temporal bone computed tomographic images and 3-dimensional reconstructed views which were all correlated with intraoperative findings. The patient was successfully treated with an ossicular prosthesis replacement.
