The maxillary sinus puncture training model is a simulation teaching aid specially designed for clinical teaching and skills training in otolaryngology, mainly used to help learners master the standardized operation of maxillary sinus puncture and drainage. This model is usually made based on the real human anatomical structure, accurately reproducing the spatial positional relationship of the nasal cavity, nasal septum and maxillary sinus. The surface material is close to the texture of human tissues, which is convenient for operation experience.

During the usage process, learners need to first familiarize themselves with the anatomical landmarks of the maxillary sinus, the position of the lower nasal passage and the puncture point, and then follow the standard procedures to carry out local disinfection, instrument preparation and puncture simulation. During operation, a needle or a specially designed puncture device can be used to enter the designated area, train the sense of touch and Angle control, and experience the drainage process after successful puncture.

This model can not only enhance students' understanding of the anatomy of the maxillary sinus, but also help them master the key points of operation and reduce the risks in clinical practice. At the same time, it also provides a reliable platform for doctors' continuing education and new technology training. Through repeated practice, learners can enhance their skills in a safe environment and lay a solid foundation for the diagnosis and treatment of clinical sinus diseases.
