Acquisition of ear anatomy is difficult because of complexity of its structure. Three-D images and prototyped models are good educational materials and their usefulness had been reported. The authors used a 3D edit function installed in the 3-D construction software (Materialize®). It allowed shaving the 3-D image while rotating and magnifying the original image. Slice by slice shaving enabled exposure of the target organ, such as inner ear structure and ossicles. This manipulation using 3-D edit function serves as a good educational tool for acquisition of the ear anatomy.
