For a Flat Small Head, Are There Implants That Can Be Inserted to Add Size to the Skull?

You should go to a board certified plastic surgeon who has done a fellowship in craniofacial surgery. There are implants that can be placed beneath your scalp and even filler agents that can do the same for more minor deformities

Hello, Thank you for asking question for skull reshaping surgery. Recently, the number of patients who are interested in skull reshaping surgery for flat head significantly increased. Cosmetic surgery for the back of the head using osteobond takes approximately 30~40 minutes and is performed by making 3-4cm incision on the upper portion of the scalp. If the back of the head is flat without sense of volume, portion of the back of the head is substantially sunk, or the head appears to be dented due to severe asymmetry, this surgical procedure can modify such into symmetrical and appropriately voluminous back head. Thank YouFrom. Dr.Kim

The most effective method to produce permanent expansion would be to use a tissue expander to enlarge the scalp prior to using an implant to augment the surface of the skull. Once the scalp has been expanded to accommodate additional volume, an implant can be used (e.g., silicone, titanium mesh, or bone cement). Injection of bone cements could produce a small increase in skull dimension but not likely one that will result in a significant aesthetic change in your appearance without prior scalp expansion.
