[1] It is equipped with fine anatomical structures including the external auditory canal, internal auditory canal, cancellous bone, auditory ossicle chain, semicircular canals and facial nerve, which enhances the accuracy and stability of training.

[2] Designed with a temporal bone replacement module, it can be customized to simulate bone quality, anatomical structures and pathological changes of different age groups, meeting diverse simulation training needs with easy replacement.

[3] The mastoid air cells in the replacement module adopt a hollow structure, which highly accurately reproduces the real anatomical structure of the human body and the tactile experience during operation.
