Skeletal Structure Of The Frontal Eminence Of The Frontal Bone Or Forehead

Description

Frontal eminences (tubera frontalia) rise as paired, smoothly convex prominences on the squamous part of the frontal bone, positioned superolateral to the glabella and superior to the supraorbital margins in an anterior skull perspective. Each tuber sits lateral to the frontal midline and medial to the temporal lines, helping define the forehead contour above the orbits. Inferiorly, the frontal bone transitions toward the supraorbital ridge and frontonasal region, while superiorly it curves toward the coronal suture with the parietal bones. Bilateral symmetry is easy to judge. These bony landmarks matter in both surface anatomy and craniofacial assessment because prominence or flattening of the frontal eminences contributes to recognizable patterns in congenital and acquired conditions, including craniosynostosis (for example, coronal synostosis with asymmetric frontal flattening), metabolic bone disease, and syndromic craniofacial dysmorphology. In trauma documentation, the tubera frontalia help orient descriptions of forehead lacerations and frontal contusions relative to the supraorbital rim and glabella, and they provide reliable reference points when correlating physical exam findings with CT-based craniofacial measurements. Subtle curvature changes become readable when the forehead convexities are isolated against adjacent bony contours. This is a palpable landmark. Use this illustration in head and neck anatomy teaching to anchor terminology around the frontal bone (squama frontalis, glabella, supraorbital margin) and in radiology, emergency medicine, or maxillofacial surgery publications when describing anterior cranial contour, external cephalometric landmarks, or preoperative planning notes for frontal reconstruction.
