  • Prognosis Prognosis is variable and depends on the presence and severity of associated cardiovascular, neurological and other complications.[patient.info]
  • The overall prognosis is highly variable dependent on the presence of other associated anomalies. Distraction osteogenesis is a surgical procedure that may be helpful.[texaschildrens.org]
  • The prognosis is generally favourable. We present a very rare case report of bony fusion between the maxillary and mandibular alveoli without any other associated anomaly.[ispub.com]
  • Thus, corroborating above statements that hypoglossia with limb anomalies has a poor prognosis. Tongue is the most agile, adept and versatile appendage in the human body.[ijdr.in]

  • In children, the bone dense barriers may not yet have developed to the point where this prevention occurs.[scielo.br]
  • Therefore there may be no prevention techniques available. Treatment: Treatment for mandibular hypoplasia requires reconstructive surgery.[medigoo.com]
