The maxillary, or maxillary sinus (sinus maxillaris) is the cavity of the upper jaw. The anterior wall of the sinus in the center is thin, thickens in the peripheral parts. This wall is formed by a part of the upper jaw between the infraorbital margin and the alveolar process. The zadnelateralnaya wall corresponds to the bucca of the upper jaw. To the anterior section of the medial wall of the maxillary sinus is a nasolacrimal canal, to the posterior part - lattice cells. The lower wall of the sinus forms the alveolar process of the upper jaw. The upper wall of the sinus is also the bottom wall of the orbit. The maxillary sinus opens into the middle nasal passage. The sinus changes in shape and size.
