HYPOPLASIA of the maxilla may cause a facial malformation, called "dishface deformity," which is characterized by saddle nose, shortening of the columella, flattening of the alar flares, and depression of the malar eminences. This configuration is associated with lack of development of the anterior nasal spine and the inferior orbital rim. The defect may encompass the alveolar rims and thus result in dental malocclusion. Radiographically, there is shortening of the normal distance from the anterior nasal spine to the nasion and to the posterior nasal spine. In addition, the anterior nasal spine may be absent or rudimentary, as often is true in patients with bilateral cleft lips.1

At birth the facial bones constitute one eighth of the cranial bulk, yet at maturity they account for one half.2 This equilibration is accomplished by anterior inferior growth of the maxilla and mandible with eruption of the teeth and the development
