A frontal bone fracture is a break in the forehead bone, which overlies the frontal sinus and lies close to the brain. These uncommon but serious injuries usually follow major blunt trauma. Displaced fractures are repaired surgically, often through a hidden scalp incision, to restore the forehead's shape and lower the risk of infection and other complications.

What is frontal bone fractures?
The frontal bone forms the forehead and lies just beneath the skin, so injuries often cause visible deformity. Fractures are rare but serious because of their closeness to the brain; if not properly treated they can lead to meningitis, brain abscess or encephalitis. Most result from blunt trauma such as road accidents, fights, sports, workplace injuries and falls, and they are often associated with brain injury or other facial fractures.
The bone has two layers (tables) with the frontal sinus between them; the sinus drains into the nose through the nasofrontal duct. Anterior table fractures mainly affect appearance: undisplaced fractures are usually managed without surgery, while displacement greater than 1 to 2 mm generally needs surgery to prevent deformity. Severely comminuted fractures may need bone grafts and obliteration of the sinus.
Posterior table fractures, nearer the brain, may cause cerebrospinal fluid (CSF) leak and are managed together with neurosurgical care, using procedures such as sinusotomy, sinus obliteration or an osteoplastic flap depending on displacement and CSF leak. A CT scan is the gold standard for assessment, along with a full eye examination, careful monitoring of consciousness and a search for other injuries.
Who is frontal bone fractures for?
- Displaced anterior table fractures (more than 1 to 2 mm) causing a visible dent
- Comminuted fractures of the forehead or frontal sinus
- Posterior table fractures or CSF leak (with neurosurgical care)
- Injury to the nasofrontal duct affecting sinus drainage
- Associated naso-ethmoidal or orbital fractures
How is it done?
- Usually done urgently after blood and urine tests, chest X-ray, ECG, CT scans, anaesthetic assessment and consent
- General anaesthesia; local anaesthetic with adrenaline reduces bleeding
- Bicoronal (scalp) incision behind the hairline avoids facial scars and gives wide exposure; occasionally an existing wound is used for an isolated anterior wall fracture
- Fragments are realigned and fixed with micro or mini plates or mesh
- Skull (calvarial) bone grafts can be taken through the same incision if needed
What is recovery like?
- Monitoring, often in the ICU initially
- Facial swelling usually subsides within a few days; any scalp drain is removed at 24 to 48 hours
- Sutures or staples are usually removed within about a week
- Paracetamol for headache; avoid aspirin and other anti-inflammatories unless prescribed
- Avoid contact sports for at least 2 months, and do not drive or operate machinery until cleared
What are the risks?
- Pain, swelling, bruising, infection and bleeding
- CSF leak, meningitis or brain abscess
- Sinus problems such as mucocoele from blocked drainage
- Persistent forehead contour irregularity
- Numbness of the forehead or scalp, and scarring

Frequently asked questions
Why are frontal bone fractures serious?
The frontal bone protects the front of the brain and contains the frontal sinus. A fracture can be associated with brain injury, leakage of brain fluid (CSF) and blocked sinus drainage, which can lead to infections such as meningitis or brain abscess if not managed properly. These injuries need careful assessment with a CT scan.
Does every forehead fracture need surgery?
No. Undisplaced fractures of the front wall of the sinus are often managed without surgery. Surgery is usually advised when the bone is pushed in by more than 1 to 2 mm, when there is significant comminution, sinus drainage injury or CSF leak, or when there is a visible deformity.
Will there be a scar on my forehead?
Usually not. Most frontal bone fractures are repaired through a bicoronal incision across the top of the head behind the hairline, which is hidden by hair. Occasionally an existing forehead wound is used to reach the fracture, avoiding a new incision.
When can I return to work and sport after surgery?
Most people need a few weeks off work, depending on their job and any associated head injury. Driving and operating machinery should wait until your doctor confirms you have fully recovered, and contact sports such as football are usually avoided for at least two months.
