Unilateral coronal synostosis, bilateral coronal synostosis and metopic synostosis all cause changes in the shape of the forehead and upper portion of the eye socket (orbit) that cause an abnormal appearance. Fronto-orbital advancement (FOA) is the surgical procedure used to reshape and reposition the forehead and upper portion of the orbits. While the deformity of the forehead and orbit varies based upon which cranial suture is affected, the ultimate goal of the fronto-orbital advancement is the same in each case. The goal of the FOA procedure in all cases is to overcorrect the position and contour of the upper portion of the eye socket(s) and forehead. In order to have a normal appearance when the child's skull is fully grown, we must place the bones of the forehead and eye socket position in a more forward position for coronal synostosis and wider position for metopic synostosis. The infant's appearance immediately after surgery does not look normal for their age, but the children grow into the overcorrection in next 1-2 years after surgery. If the forehead and upper eye socket are not overcorrected, the face and skull will initially look normal but will have an abnormal appearance (similar to the original head shape) when the child is fully grown. Below are some examples of patients before and after fronto-orbital advancement.
