ABSTRACT
In young patients whose mandibles are still growing actively, damage to the condylar growth centres due to trauma, fracture, sepsis or juvenile chronic arthritis can result in very marked unilateral condylar and hence hemimandibular hypoplasia. In some children this condition may be bilateral. Severe micrognathia can result and during the adolescent growth phase, the failure in mandibular growth becomes more noticable against the relatively normal maxillary maturation.
