N2 - Maxillary hypoplasia is a growth-related dentofacial deform- ity characterized by concave facial profile, transverse maxillary deficiency, anterior open bite, crowding, compromised nasal respiration and class III-malocclusion. Maxillary growth dis- turbances and transverse maxillary deficiencies can often be compensated and corrected by growth modification if timely interceptive treatment is initiated. However, severe maxillary hypoplasia often requires orthognathic surgery involving sur- gically assisted maxillary expansion with midpalatal osteotomyand/or segmented Le Fort I osteotomy. Absence of corrective treatment of growth deficiencies in the dentoalveolar and ba- sal jaw relationship in maxillary hypoplasia can lead to chew- ing and functional disorders, malocclusion, functional man- dibular shift, crowding, psychosocial problems and abrasion of teeth. Early diagnosis and initiation of relevant interceptive treatment are therefore important in maxillary hypoplasia and class-III malocclusion to achieve a satisfactory treatment outcome with the fewest possible invasive procedures and discomfort for the patient. In this review article, dentoalveolar and basal characteristics of maxillary hypoplasia and class III- malocclusion are discussed, as well as treatment options.
