Abstract

Duplication anomalies of the internal auditory canal are rare, with only twenty-one cases reported in literature. These range from incomplete partition and complete partition to true duplication. We present three cases showing this entire spectrum of duplication abnormalities and discuss the role of imaging in the preoperative work up of such patients planned for cochlear implant.
