Maxillary Process

The maxillary process (processus maxillaris) is a process that is located on the inferior turbinate and covers the lower part of the entrance to the upper jaw. It has a flat shape and extends from the upper edge of the shell down and to the side, covering the lower part of the sinus.

The maxillary process may also be called processus maxillaris according to the International Anatomical Nomenclature (PNA), British Anatomical Nomenclature (BNA), or Japanese Anatomical Nomenclature (JNA).

In addition, in human anatomy there is a term processus maxillaris to designate the anteroinferior process of the zygomatic bone. This process connects with the zygomatic process on the upper jaw and forms the zygomatic-maxillary junction.

The maxillary process is a process that is located on the inner surface of the nasal cavity, which is called the maxillary sinus. This process is a flat structure that originates at the superior border of the inferior turbinate and moves downward and outward toward the cheekbone. It can be part of the cheekbone as well as the upper jaw.

This appendage has several key functions. Firstly, it closes the entrance hole to the maxillary region. This protects the maxillary sinuses from infection or other particles from the external environment. In addition, it delimits the superior spaces themselves and reduces the sound intensity in these areas. Another important function of the processes is to increase the patency of the auditory tubes and more efficient ventilation. The maxillary process is attached to a membrane that separates the upper respiratory tract from the nasopharynx. As a result, a thinner membrane allows air to pass through the nasal passages faster and more easily.

The maxillary processes play an important role in anatomy. Understanding their structure and function can be useful for physicians working with the craniofacial region, including otolaryngologists and dentists. In the case of a pathological process in the upper cervical region, knowledge of anatomy
