Cleft lip and cleft palate

Cleft lip and cleft palate can occur on one side (unilateral cleft lip and/or palate), or on both sides (bilateral cleft lip and/or palate).

(cleft)


Cleft lip and cleft palate1

Cleft lip and cleft palate

  • comprise the fourth most common birth defect in the United States. One of every 700 newborns is affected by cleft lip and/or cleft palate.

Cleft lip

Cleft lip

  • A cleft lip is a separation of the two sides of the lip. The separation often includes the bones of the upper jaw and/or upper gum.

Cleft palate

Cleft palate

  • A cleft palate is an opening in the roof of the mouth in which the two sides of the palate did not fuse, or join together, as the unborn baby was developing.

Cleft lip and cleft palate

  • Because the lip and the palate develop separately, it is possible for the child to have a cleft lip, a cleft palate, or both cleft lip and cleft palate.

Embryology

Embryology

  • Cleft lip and cleft palate are congenital defects, or birth defects, which occur very early in pregnancy.

Detection of Cleft Lip: Ultrasound


Etiologic factors

Etiologic factors

  • The majority of clefts appear to be due to a combination of genetics and environmental factors.

Embryology facial development

Embryology: Facial Development

  • 1. Development of human face starts during the 4th week of embryonic development.

  • 2. By 6th week, the external face is completed.

  • 3. Between the 6th and 8th weeks, the palatal development divides the nasal and oral cavities.

  • 4. By 12th weeks, the completion of soft palate


Fusion

Fusion

  • Fusion is the growing together process of two facial swellings, which were initially separated by a space.

Serial occlusal radiographs of the cleft area of a child from the grafted group. A. after orthopedic arch alignment prior to bone grafting; B. immediately after insertion of bone graft; C. & D. slow progressive resorption of the bone graft. Arrow points to the alveolar cleft and the bone grafted area.
