AbstractDevelopmental, traumatic and congenital factors, among many others, may lead to transverse maxillary deficiency (TMD). TMD can be corrected by orthodontic treatment, and may also require surgical intervention. The surgical technique is used in maxillary hypoplasia seen in cleft palate, crowding in maxillary teeth, which in cases where maxilla needs to be expanded more than 5 mm. Although it is a frequently used technique, there is no consensus on the operative technique and the apparatus used during the operation. Whether or not to separate, the pterygomaxillary junction is also one of the most common subjects of debate in this regard. In this case presentation, the transverse expansion of the maxilla was completed by means of surgically-assisted rapid maxillary expansion operation performed under local anesthesia without separating the pterygomaxillary junction and nasal septal osteotomy; and the patient, in whom orthodontic treatment had been completed, made a successful recovery without complications.
