In modern ENT assistant training, before starting ear surgeries on patients, it is very important to learn these surgeries by performing them on ear bones (temporal bones) taken from cadavers. However, while it is very difficult to obtain cadaver bones for this purpose in our country, the participation of assistants in cadaver temporal bone courses organized by various institutions for this purpose is a very costly process financially. In order to overcome these problems, artificial ear bones produced from 3D printers with all their anatomical details are used in our clinic, ensuring that our assistants receive these surgical trainings in their own institutions without the need for cadaver bones.
