I hit my head 3 yrs ago, it formed a bump on my forehead, made of bone (right side). Can this be removed by a surgeon? (photos)

Thanks for your question. Exostosis is a benign bony growth that can occur due to various factors, including genetics, chronic irritation, or unknown causes.
In injury-Induced Bone Growth a severe head injury can trigger abnormal bone growth as the body attempts to repair the damaged tissue. In some cases, this can lead to the formation of a bony growth, although this is relatively rare.
If the injury causes persistent inflammation or irritation to the bone, it can stimulate excessive bone growth, leading to exostosis. Some individuals may have a genetic predisposition to develop exostosis and a head injury could potentially trigger this genetic tendency.
Treatment for exostosis often depends on its location, size, and whether it's causing any symptoms.

The main alternatives for therapy are as follows:

Observation: If the exostosis is minor with little symptoms, we could advise just keeping an eye on it or using conservative measures like pain management with over-the-counter medications like acetaminophen or ibuprofen if the bony protrusion causes discomfort.
Surgery could be suggested if conservative measures are ineffective or if the exostosis is seriously affecting your look or giving you discomfort.
The main surgical methods for eliminating a forehead exostosis are as follows:
Excision Directly
Using specialized equipment, a direct incision is made over the exostosis or in the hairline around it. The bony growth is gently removed, and the wound is then closed.
Endoscopic Surgery:
A minimally invasive technique involving small incisions. A tiny camera and surgical instruments are inserted through these incisions.The exostosis is removed with precision, resulting in minimal scarring.
A Board Certified Plastic Surgeon should examine you to determine the size, position, and form of the exostosis in order to choose the best surgical procedure.
Hope this was helpful!

Forehead bump treatment can be removed IF it is thickening of the bone as shown on MRI. See a surgeon who is experienced with this surgery.
