Infraorbital Region, Anterior View

Description

Centered on the anterior midface, the highlighted infraorbital region lies inferior to the orbital rim and lateral to the nasal sidewall, spanning the maxillary surface toward the buccal (cheek) area. Medially it approaches the nasofacial junction near the ala of the nose, while laterally it blends toward the zygomatic prominence. Deep to the skin in this territory sit the maxilla, the infraorbital foramen, and the emerging infraorbital neurovascular bundle (infraorbital nerve, artery, and vein) that fans out to supply the lower eyelid, lateral nose, and upper lip. Clear surface anatomy. Clinically, this is the map for maxillary (V2) sensory symptoms and local anesthesia: an infraorbital nerve block targets the nerve as it exits the infraorbital foramen, commonly used for laceration repair of the upper lip, nasal vestibule, and lower eyelid, as well as dental procedures involving anterior maxillary teeth. Trauma patterns also localize here, since zygomaticomaxillary complex injuries and orbital floor blowout fractures can produce infraorbital hypoesthesia from nerve contusion or entrapment along the infraorbital groove and canal. Facial injectables intersect the same risk zone, where filler or cannula placement too close to the infraorbital vessels can raise the stakes of vascular compromise. Medical educators can drop this into head and neck anatomy teaching to anchor the boundaries between the infraorbital, nasal, and buccal regions in standard anatomical position, while also addressing how surface landmarks vary with facial morphology and skin tone in a Black female model. It also fits ENT and maxillofacial surgery texts discussing maxillary sinus disease referral patterns and approaches around the infraorbital rim and midface.
