title: Anteverted internal auditory canal as an inner ear anomaly in patients with craniofacial microsomia.
abstract: Craniofacial microsomia involves structure of the first and second branchial arches. A wide range of ear anomalies, affecting external, middle and inner ear, has been described in association with this condition. We report three cases of anteverted internal auditory canal in patients presenting craniofacial microsomia. This unique internal auditory canal orientation was found on high-resolution computed tomography of the temporal bones. This internal auditory canal anomaly is yet unreported in craniofacial anomalies.
