Question: 1 / 1775

The maxillary sinus is located in which bone of the skull?

Frontal bone

Maxilla

The maxillary sinus is primarily located within the maxilla, which is the upper jaw bone. This sinus is one of the paranasal sinuses and plays a role in reducing the weight of the skull, providing resonance to the voice, and assisting with the drainage of mucus from the nasal cavity. The maxilla bones are situated laterally to the nasal cavity and are the bodies that contain these cavities known as maxillary sinuses. Understanding the anatomy of the maxilla is crucial for dental professionals, as infections or issues in the maxillary sinus can have implications for dental health and treatments, particularly in procedures involving the upper molars.
