The maxilla and especially the mandible are hypoplastic, showing accentuation of the antegonial notch and a steep mandibular angle, which gives the impression that the body of the mandible is bending in an inferior and posterior direction. The ramus is especially short. The condyles are positioned posteriorly and inferiorly. The maxillary sinuses may be underdeveloped or absent.
