Anterosuperior view of reflected scalp over forehead. The anterior scalp (full thickness) has been pulled inferiorly over the superior margins of the orbit and bridge of the nose. The frontal bone is exposed along with the paired nasal bones in the midline. The frontonasal suture is visible. Lateral to the nasal bones are the frontal processes of the maxilla. Attaching to the frontal processes are anterior components (anterior crus) of the medial canthal ligaments. These, in concert with posterior portions of the ligament (posterior crus), which attach to the posterior lacrimal crest of the lacrimal bone, enclose the lacrimal sac within the lacrimal fossa. Orbital contents enclosed by periorbita can be seen at the orbital margin. (Image courtesy of AL Rhoton, Jr.)
