The Structure And Location Of The Canine Fossa On The Maxilla

Description

Anterior maxilla comes into view with the canine eminence (jugum caninum) rising on the facial surface, and the canine fossa appearing as a shallow depression just lateral to it, inferior to the infraorbital margin and superior to the alveolar process. The animation tracks the fossa in relation to the root prominence of the maxillary canine and the adjacent maxillary sinus, with the depression deepening as lighting and angle shift across the facial aspect of the bone. Medially, the fossa tapers toward the piriform aperture, while laterally it approaches the zygomatic process region. Clear bony topography. Surface anatomy of the canine fossa matters because it sits over thin anterior maxillary bone and lies close to the infraorbital neurovascular bundle as it exits the infraorbital foramen, a common site for regional anesthesia planning and for avoiding iatrogenic injury. Dental infection from the maxillary canine and anterior teeth can track into the canine (infraorbital) space, producing swelling that lifts the upper lip and can spread toward the lower eyelid, and the sequence helps learners link that clinical pattern to the underlying depression. Showing the fossa relative to the canine eminence also clarifies why maxillary sinusitis and periapical disease can present with referred facial tenderness in this region. Use this animation in head and neck anatomy labs, dental anatomy and local anesthesia teaching, and oral and maxillofacial surgery modules covering vestibular incisions, canine space infections, and anterior maxillary approaches; it also fits figure callouts for atlases and patient education on odontogenic facial swelling patterns.
