Anterior wall of the maxillary sinus

The anterior wall of maxillary sinus is in continuation with the roof, and it houses the end of the infraorbital nerve, which runs through the infraorbital canal along the roof of the sinus and sends branches to the soft tissues of the cheek. The thinnest portion of the anterior wall is above the canine tooth, called the canine fossa, which is an ideal entry site for addressing various disease processes of the maxillary sinus.
