Anterior View of the Frontal Bone and Superior Margin of the Orbit

Surgical Correlation


Anterior view of the frontal bone and superior margin of the orbit. All soft tissue has been removed in this preparation which shows the frontal bone with a midline metopic suture that continues posteriorly as the sagittal suture. The anterior inferior surface of the frontal bone serves as the roof of the orbit and its anterior inferior border is the superior margin of the orbit. At the junction of the medial one-third and lateral two-thirds of this margin is the supraorbital notch or foramen for the supraorbital neurovasculature, which leaves the orbit to supply the upper eyelid, forehead, and anterior scalp. At the midline, the frontal bone articulates with the paired nasal bones at the frontonasal suture. The lateral rim of the orbit is formed by portions of the frontal and zygomatic bones. (Image courtesy of AL Rhoton, Jr.)
