Glabella Of The Frontal Bone, Anterior View

Description

Glabella occupies the midline prominence of the frontal squama between the right and left superciliary arches, forming the bony contour that corresponds externally to the area between the eyebrows. From this fixed anterior perspective, the paired supraorbital margins lie inferior and lateral to the glabella, while the more convex frontal eminences sit superior and lateral on the forehead. Inferiorly, the contour transitions toward the nasion at the frontonasal junction, a key landmark where the frontal bone meets the paired nasal bones. Facial trauma assessments often reference the glabella because it sits at the anterior buttress of the upper face, just superior to the nasofrontal suture and adjacent to the frontal sinus region, where impact can propagate into the anterior cranial fossa. Small deviations from midline symmetry at the superciliary arches can hint at displaced frontal bone fractures or post-traumatic contour irregularity, and the glabella is a reliable external correlate when planning incision placement or palpation during examination. Surface anatomy teaching also benefits from this bony focus, since the glabella helps orient learners to nearby landmarks such as the supraorbital notch or foramen (when present) for the supraorbital neurovascular bundle and to the midline metopic suture when it persists into adulthood. A compact landmark. Use this illustration in gross anatomy labs, head and neck modules, and radiology or emergency medicine teaching files that introduce frontal bone landmarks used in trauma documentation and surgical planning. It also suits craniofacial and ENT publications that need a precise anterior reference for the glabellar region without distracting soft-tissue detail.
