Squamous Part Of The Frontal Bone In Anterior View

Description

Frontal squama dominates the anterior cranial vault, forming the bony forehead superior to the orbital roofs. From this fixed anterior perspective, the glabella lies on the midline between the superciliary arches, while the frontal tubera sit more superolaterally and the temporal lines curve laterally toward the zygomatic processes of the frontal bone. Inferiorly, the supraorbital margins frame the superior orbital apertures, with the supraorbital notch or foramen positioned near the junction of the medial and middle thirds, and the superior border approaches the coronal suture where the frontal bone meets the parietals. Surface landmarks on the frontal squama guide both diagnosis and operative planning. Palpation tenderness over the supraorbital rim often tracks with anterior table frontal sinus fractures, and the relationship of the supraorbital notch/foramen to the rim matters when local anesthetic is placed for supraorbital nerve blocks during laceration repair or brow procedures. Attention also falls on the midline: persistence of the metopic suture or a prominent frontal crest can be mistaken for fracture on trauma imaging, so a clean anterior bony profile helps teach normal variants versus pathology. A key landmark. Use this illustration in gross anatomy and osteology modules to anchor cranial sutures, forehead contours, and the bony limits of the orbit, or in surgical education for frontal craniotomy planning where burr-hole placement must respect the frontal sinus and supraorbital neurovascular bundle. It also fits radiology and emergency medicine teaching materials that correlate forehead impact patterns with frontal bone and sinus injury.
