Anatomy, Head and Neck: Frontal Bone

Excerpt

The frontal bone forms the anterior and superior portion of the skull (see Image. Frontal Skull). At the beginning of life, this bone is separated by a temporary suture called the "frontal suture," which fuses as part of normal development to form the singular frontal bone (see Image. Frontal Bone, Outer Surface). The frontal bone plays a vital role in protecting important neural structures and forms the superior aspect of the orbit. Frontal bone fractures occur in roughly 5% to 15% of all traumatic facial fractures.

Clinically, the frontal bone holds significant importance in both medical and surgical contexts. This bone's proximity to the frontal sinus, brain, and orbit means that fractures or infections can result in serious complications, including cerebrospinal fluid leaks, orbital injuries, and intracranial involvement. In aesthetic medicine, the frontal bone also plays a foundational role in forehead contouring and facial rejuvenation procedures. Understanding the anatomy of this bone aids in accurate diagnosis, surgical planning, and prevention of complications.
