      1. Cleft Lip: 1 in 750 white births
      2. Isolated Cleft Palate: 1 in 2500 white births
  3. Risk Factors
    1. Family History (e.g. van der Woude Syndrome)
      1. Recurrence rate: 2-6% depending on history
    2. Ethnicity
      1. Asian patients have highest risk
      2. Black patients have lowest risk
    3. Epilepsy and maternal anticonvulsant use
  4. Pathophysiology
    1. Embryonic Timing of lip and Palate defects
      1. Occurs prior to 37 days post-conception
    2. Cleft Lip
      1. Failed medial nasal and Maxillary closure
      2. Extension to Cleft Palate in 42% of cases
    3. Isolated Cleft Palate
      1. Failed fusion of palatal shelves
  5. Signs
    1. Cleft Lip (with or without Cleft Palate)
      1. Variable involvement
        1. May involve only vermilion border
        2. Some cases extend into Palate and floor of nose
      2. May be associated with tooth abnormalities
      3. Unilateral or bilateral cleft
      4. Often associated with Columella abnormality

      3. Septo-optic dysplasia
      4. Kallmann's Syndrome
  7. Management: Feeding
    1. Breast Feeding infant
      1. See Lactation for Infant with Cleft Lip or Palate
    2. Bottle Feeding infant
      1. Consider plastic obturator to cover Palate
      2. Soft artificial nipple with large openings
      3. Squeezable bottle
  8. Management: Surgery
    1. Perioperative Concerns
      1. Pre-operative criteria
        1. No signs of infection
        2. Child well hydrated
      2. Post-operative care
        1. Gentle nasal aspiration
        2. Fluid intake only for first 3 weeks after surgery
        3. Child must be kept from touching surgical site
    2. Cleft Lip Repair
      1. Z-Plasty repair with staggered Sutures minimizes scar
      2. Repaired at age 3 months
      3. Revision may be needed at age 4-5 years
    3. Corrective Nasal Surgery
      1. Repaired at lip repair or at adolescence
    4. Cleft Palate Repair
      1. Timing of repair variable based on type of defect
      2. Usually repaired before age 1 for normal speech
      3. Contoured speech bulb if surgery delayed after age 3
  9. Complications
    1. Recurrent Otitis Media
    2. Hearing Loss
    3. Tooth malposition requiring orthodontics
    4. Speech deficits (may persist after repair)
      1. Difficulty with explosive sounds: "p, b, d, t, h, y"
      2. Difficulty with hissing sounds: "s, sh, ch"

Cleft Lip (C0008924)

Definition (NCI) A congenital abnormality consisting of one or more clefts (splits) in the upper lip, which may be accompanied by a cleft palate; it is the result of the failure of the embryonic parts of the lip to fuse.
Definition (MSH) Congenital defect in the upper lip where the maxillary prominence fails to merge with the merged medial nasal prominences. It is thought to be caused by faulty migration of the mesoderm in the head region.
Definition (CSP) congenital defect in the upper lip where the maxillary prominence fails to merge with the merged medial nasal prominences; thought to be caused by faulty migration of the mesoderm in the head region.

Cleft Palate (C0008925)

Definition (NCI) A congenital abnormality consisting of a fissure in the midline of the hard and/or soft palate; it is the result of the failure of the two sides of the palate to fuse during embryonic development.
Definition (MSH) Congenital fissure of the soft and/or hard palate, due to faulty fusion.
Definition (CSP) congenital fissure of the soft and/or hard palate, due to faulty fusion.
