Since we are separating a mid palatal suture, it is better to do this procedure at a younger age before the palatal suture becomes fused. With adults, the maxilla can be expanded by using an RPE and having surgery performed by an oral surgeon. This procedure is called Surgically Assisted Rapid Palatal Expander (SARPE). During the surgery the palatal suture is opened with side releasing incisions and all the expansion is completed at one time.
