Dentofacial deformity of myotonic dystrophy is long face, open bite, high arch palate and V shaped dental arch of the maxilla. In such a case, it is necessary for the meticulous evaluation of deformities to correct these conditions simultaneously.<BR>In this report, the authors present a case of myotonic dystrophy associated with dentofacial deformity and the method of preoperative evaluation, especially about model surgery with the Whip-Mix articulator.<BR>The authors' surgical procedure under these conditions is total maxillary alveolar ostcotomy advocated by Walford and Epkcr with segmental osteotomy and sagittal spliting osteotomy of the mandibular rami. We think these procedures are versatile and stable for the long face associated with the high arch palate.
