INTRODUCTION. The paranasal sinuses (âthe sinusesâ) are air-filled cavities located within the bones of the face and around the nasal cavity and eyes. Each sinus is named for the bone in which it is located: Physiology.
The maxillary sinus is one of the four paranasal sinuses, which are sinuses located near the nose. The maxillary sinus is the largest of the paranasal sinuses. The two maxillary sinuses are located below the cheeks, above the teeth and on the sides of the nose. The maxillary sinuses are shaped like a pyramid and each contain three cavities, which point sideways, inwards, and downwards. The sinuses are small air-filled holes found in the bones of the face. They reduce skull weight, produce mucus, and affect the tone quality of a person's voice. The maxillary sinus drains into the nose through a hole called the ostia. When the ostia becomes clogged, sinusitis can occur.
