What it is.
An osteoma is a benign growth of the skull bone.
It is usually visible or palpable beneath the scalp. Typically, it feels firm and smooth to the touch. However, over time, these growths are usually observed to develop very slowly or not at all.
They may appear as single lumps or in multiple locations.
A CT scan is performed to confirm the diagnosis and ensure there is no underlying abnormality.
Purpose of the surgical procedure
The goal is usually to remove it completely in a single procedure in order to improve appearance and prevent any further growth. Surgery for osteomas is typically curative.
The procedure
The surgical procedure is usually performed under general anesthesia. The scar is typically located behind the hairline. The osteoma is identified on the surface of the bone and removed using a drill or cutting tool.
After the procedure
The patient can usually get out of bed on the same day as the surgery and may go home the following day.
Stitches are typically removed one week after the procedure.
Complications
There is a small risk of wound infection, which may require antibiotics.
Rarely, in the case of large osteomas, there may be a slight risk of bleeding in the space beneath the skull.
