Where is the left frontal bone?
The frontal bone is located in front of the skull, above the nasal bones and in front of the parietal bones, which form the sides of the skull. The frontal bone is also surrounded by seven articulating bones to create joints.
What is a frontal bone fracture?
Frontal bone (forehead) fractures: The frontal bone is the main bone in the forehead area. A high-impact injury to the head can cause a fracture of the frontal bone and floor of the sinuses. The fracture is mostly likely to occur in the middle of the forehead. That’s where the bone is the thinnest and weakest.
What is the bone in the front of your head?
The frontal bone is a bone of the skull found in the forehead region. It is one of eight bones that form the cranium, or brain case. The frontal bone plays a vital role in supporting and protecting the delicate nervous tissue of the brain. It gives shape to the skull and supports several muscles of the head.
What does the frontal bone contain?
The frontal bone has an involvement in the formation of the pterion, a joining of four cranial bones: frontal, sphenoidal, parietal, and temporal. Lastly, the anterior aspect of the frontal bone contains two frontal sinuses, each superior to the orbital roof.
How hard is frontal bone?
The frontal bone can resist 400 to 1000 kg before fracture, thus it is secondary to high-velocity trauma and, by nature, commonly has concomitant facial fractures. Fractures of the frontal bone area frequently extend to the orbital roof, nose, dura, and frontal lobe.
Is the frontal bone strong?
In comparing the impact strength of three facial bones on each of four cadavers, the frontal bone has been found to tolerate a force three or four times higher than the mandible and zygomatic bone which are about equal.
How much force does it take to break a frontal bone?
The force needed to fracture the frontal bone is between 800 and 1600 pounds,[2] which is double the force needed to fracture the mandible and five times that needed to fracture the maxilla. The “Posterior” or “Inner” table is much thinner, just 0.1–4.8 mm in thickness, and it forms part of the anterior cranial fossa.
Do we have 2 frontal bones?
The bone consists of two portions. These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively….

Why does my temporal bone hurt?
stress, tooth grinding, direct trauma to the Temporalis muscle, excessive gum chewing. In rare cases a condition called Coronoid Process Hyperplasia may be the cause of Temporal Tendinitis. The diagnosis of Temporal Tendinitis by palpation of the tendon as it inserts into the coronoid process.
Does the frontal bone contain a sinus?
There are two, large frontal sinuses in the frontal bone, which forms the lower part of the forehead and reaches over the eye sockets and eyebrows. The frontal sinuses are lined with cells that make mucus to keep the nose from drying out. Anatomy of the paranasal sinuses (spaces between the bones around the nose).
Why is the frontal bone important?
The main function of the frontal bone is to create the smooth curvature of the forehead and to provide protection for the frontal lobe of the brain. In addition, it participates in the formation of several cavities of the skull such as the orbit and the anterior cranial fossa.
What does the frontal bone attach to?
Within the cranium, the frontal bone connects with the ethmoid bone inferiorly and medially. Posteriorly and inferiorly, the frontal bone meets the sphenoidal bone. As the frontal bone ascends posteriorly and laterally, it will meet the temporal bone, then finally the parietal at the top of the skull.
Is a frontal bone fracture a skull fracture?
The frontal bone is the most frequently fractured cranial bone in craniofacial trauma patients and accounts for 37% of cranial fractures.
Can the skull repair itself?
Overall, most skull fractures heal on their own and don’t need surgery as long as there aren’t associated injuries to other structures such as the brain.
At what age does the frontal bone develop?
Frontal bone growth and development begins as two halves with the initial formation of primary ossification centers in utero between the sixth and seventh week (Scheuer and Black, 2000) and continues until complete fusion of the metopic suture takes place, generally by the fourth year of life.
