Anterior View of Frontal, Nasal, and Maxillary Bones

Surgical Correlation

Anterior view of frontal, nasal, and maxillary bones. The frontal bone is a single bone in the adult. It forms the superior border of the orbit and contains along its superomedial margin the supraorbital notch (or foramen) for transmission of the supraorbital neurovasculature to the upper eyelid, forehead, and scalp. In the midline, the frontal bone articulates with the narrow, paired nasal bones at the frontonasal suture. The lower edges of the nasal bones form, with the medial margins of the maxillary bones, the anterior nasal aperture to which the cartilages and soft tissue of the external nose attach. The maxillary bones form the skeleton of the central part of the face and form most of the floor of the orbit. Just below the inferior margin of the orbit are the infraorbital foramina for transmission of the infraorbital neurovasculature to the lower eyelid, lateral surface of the nose, and upper lip. (Image courtesy of AL Rhoton, Jr.)
