Differential Diagnosis
(In A Page: Pediatric Signs and Symptoms)
-
Cleft lip with or without cleft palate
–Incidence 1/500–1/2,500
–Highest incidence among Native Americans
–Defects are unilateral in 80%
–More common in boys
–Pathogenesis is multifactorial
-
Isolated cleft palate
–Incidence 1/2,000
–More common in girls
- Pierre-Robin sequence
–Micrognathia, glossoptosis (posterior displacement of the tongue to pharynx), and cleft palate
–Incidence 1/2,000–1/30,000
–Mortality 2.2–26%
- Syndrome-associated cleft lip with or without cleft palate
–Accounts for 30% of cases
–Over 300 syndromes include this phenotype
–Stickler syndrome (25%): Pierre-Robin sequence with severe progressive myopia and arthritis in young adulthood
–Velocardiofacial syndrome (15%): Slender hands and fingers, cardiac defects (TOF, VSD, right aortic arch), prominent nose; deletion of 22q11.21
–DiGeorge syndrome: Thymic hypoplasia, hypoparathyroidism, cardiac defects (truncus arteriosus, interrupted aortic arch) same spectrum at velocardial facial with same deletion of 22q
–Trisomy 13: Microcephaly, cutis aplasia, polydactyly cardiac defects
–Trisomy 18: Low-set ears, clenched hands, rocker bottom feet, cardiac defects
–van der Woude syndrome: Cleft palate associated with lip pits

Physical exam
–Location and extent of the defect
–Presence or absence of submucosal cleft palate (must
be palpated, because it may not be visible beneath the
oral mucosa)
–Dental examination
–Cardiac examination
-
Studies
–Syndromic cleft lip with or without cleft palate is detected at fetal ultrasound in 38% of cases
–Nonsyndromic clefting is difficult to see on fetal ultrasound
–Screening Echo for cardiac anomalies and
–Chest X-ray for presence of thymus
-
Screenings

Cleft lip and cleft palate:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
A typical clinical picture confirms the diagnosis. Cleft lip with or without cleft palate is obvious at birth; occasionally, more severe defects may be seen with diagnostic prenatal ultrasonography. Cleft palate without cleft lip may not be detected until a mouth examination is done or until feeding difficulties develop.
