Medical teaching and practice need to introduce the ear examination model, which mainly stems from many aspects of consideration and demand.

Firstly, the ear examination model provides an intuitive and real teaching tool for medical teaching. In medical education, it is often difficult for students to directly contact real patients for the practice of ear examination, but the ear examination model can simulate the real ear structure and pathology, providing students with abundant practice opportunities. This kind of intuitive and real teaching experience can help students better understand and master the skills of ear examination and improve the teaching effect.

Secondly, the ear examination model also plays an important role in medical practice. In the real medical environment, doctors need to face a variety of complex ear diseases and patients, and the ear examination model can provide a safe and risk-free practice platform for doctors. Doctors can perform repeated exercises and simulation operations on the model to improve their examination skills and diagnostic accuracy. This will not only help doctors respond more confidently to situations in practice, but also reduce medical errors and patient risk.

In addition, the ear examination model has the characteristics of repeatability and standardization. Compared with real patients, the model can be used repeatedly, and the teaching quality will not be affected by changes in the patient's condition. At the same time, the model can also be customized and adjusted according to the teaching needs to meet the different stages and levels of teaching needs. This repeatability and standardization makes ear examination models an important tool in medical teaching and practice.

Finally, the introduction of the ear examination model is also helpful to promote the innovation and development of medical teaching. With the continuous progress and update of medical technology, new examination methods and treatment techniques continue to emerge. As a new teaching tool, ear examination model can help students and doctors better understand and master these new technologies and new methods, and promote the innovation and development of medical teaching.

To sum up, medical teaching and practice need to introduce ear examination model, which can not only improve teaching effect and doctors' examination skills, but also provide patients with safer and more accurate medical services.
