The operation process of the middle ear anatomical model is mainly used to help learners familiarize themselves with the anatomical position and function of the middle ear cavity and related structures. The operation steps need to be carried out in a standardized manner.

First of all, before use, the integrity of the model should be checked to ensure that the tympanic membrane, ossicular chain, eustachian tube, semicircular canal and cochlea are clearly distinguishable.

When operating, first place the model on a stable table and gradually disassemble or rotate the disassembled parts of the model according to the teaching purpose. Generally, starting from the external auditory canal and tympanic membrane, the malleus, incus and stapes behind the tympanic membrane are displayed layer by layer, and their roles in sound wave conduction are explained.

Subsequently, the anatomical relationship between the middle ear and the inner ear, as well as the eustachian tube, can be demonstrated to illustrate its significant role in balancing air pressure and maintaining auditory function. During the operation, be careful to handle with care to avoid damaging the delicate structural components.

When teaching, Pointers or marks can be used for explanation to help students establish spatial concepts. Finally, restore the model to its original state and store it properly to maintain its stability for long-term use. Through this process, learners can not only intuitively grasp the fine structure of the middle ear, but also better understand the pathological basis of ear diseases such as otitis media and conductive deafness, thereby improving the learning effect of combining theory with practice.
