A CT facial bone scan is a medical imaging test that uses X-rays and computer technology to create detailed images of the facial bones. It is used to diagnose and evaluate conditions such as fractures, tumors, infections, and congenital abnormalities affecting the facial bones. The procedure is safe and non-invasive, but does involve exposure to radiation. After the scan, a radiologist will review the images and provide a report to the treating physician for diagnosis and treatment planning.
