Can My Irregular Forehead Shape After A Craniotomy Be Fixed?
Q: Over 10 years ago, I was involved in a car accident and ended up getting a craniotomy and evacuation of a subdural blood clot. Afterward, the craniotomy flap got infected and had to be removed. Because I was a child at the time, some bone actually grew back over the upper forehead defect. But it was not of the same thickness or amount and I have been left with a flat and irregular upper forehead area around my hairline and into the very visible part of my forehead. It is quite noticeable and embarrassing for me and I have always wanted to get it fixed. I have read recently through your writings that it can be repaired with some types of materials that are applied to the outside of the bone. That has given me great hope that there is a solution to this embarrassing problem. I am tired of people staring it! Please tell me about this procedure and how it is done.
A: Based on your description alone, it sounds like you would be an excellent candidate for an onlay cranioplasty procedure. Compared to what you have been through previously, this is a relatively simple operation that produces immediate results. Since you had a craniotomy previously, you have an existing scalp scar. The scalp ius lifted up again and a synthetic cranioplasty mixture is used to apply to the defect and make it perfectly smooth with the rest of the forehead. The available mixtures are a powder and liquid, which when combined, turns hard after it is shaped within a few minutes. There are three specific cranioplasty materials. I would choose hydroxyapatite, specifically Mimix, for your cranioplasty as it is the most like bone and has excellent working charcteristics. I have worked with it for over 15 years, including through its research and development phase, so I know its working properties very well. This is an outpatient procedure under general anesthesia that would take about 90 minutes to do.
