Head
 Enlarged
fontanelle
 Hair- swirls/white forelock
 Eyes- congenital cataracts, extra folds,
hyper/hypotelorism, upslant/downslant
 Choanal atresia
 Ear pits/tags, position/rotation
 Cleft palate/lip
 Prominent frenula/tongue tie
Red Reflex
• Rule out opacities between the cornea and
the retina
• Congenital glaucoma: can see large eyes,
excess tearing and cloudy corneas. This
condition can be clinding
• An infant with consistently white pupils might
have a retinoblastoma tumor
Red Reflex
Tongue Tie (Ankylogossia)
Neck and Chest

Cystic hygroma
Thyroglossal duct cyst
Branchial cleft cyst
Pectus excavatum
Extra mamillary tissue (3rd nipple)
Heart murmur- congenital heart disease
Thyroglossal Duct Cyst
Pectus Excavatum
What syndrome is this?
Extranumerary nipple
Abdomen and GU
• Omphalocele/gastroschesis/umbilical hernia
• Scaphoid abdomen- ?congenital diaphragmatic
hernia
• Femoral pulses- aortic coarctation
• Undescended testes
• Virilized female
• Fistulas, hypospadia/epispadias, imperforate
anus, Hirschprung’s
• Posterior urethral valves (no urinating)
Imperforate Anus
Hypospadias
Virilized female
Extremities and Skin

Congenital Hip dysplasia
Extra digits
Single palmar crease
Clubbed foot
Congenital nevi
Hemangiomas
Club Foot
hemangioma
Cleft lip/palate
• Incidence: about 1 in 600 live births
• Cleft lip with or without cleft palate
• Syndromic: associated with another syndrome.
Syndromic cleft lip/palate is more common in
males
• Nonsyndromic: isolated finding, not associated
with any particular syndrome. Non syndromic
tends to be equal between males and females.
• Consider submucous cleft palate with bifid uvula
Causes
• Multifactorial: combination of hereditary and
environmental factors involved in growth and
development
• Interference with normal development- within the 1st
few months of development
• Medications such as phenytoin, steroids, retinoids
(Vitamin A derivatives)
• Alcohol, hypoxia and dietary deficiencies have been
implicated
• Both single and multiple genes
Cleft lip/palate
Syndromes
•
•
•
•
•
DeGeorge/velocardiofacial/22q deletion
Pierre Robin malformation sequence
Apert syndrome
Crouzon syndrome
Treacher-Collins
Complications
• Feeding problems
• Eustacian tube dysfunction secondary to
abnormal muscle placement -> serous
otitis/middle ear disease/chronic ear
infections -> hearing problems
• Speech problems
• Dental problems
• Team approach needed: medical/surgical,
dental, speech and hearing
Treatment
• Surgical repair- usually by plastic surgery- can
affect maxillofacial growth pattern
• Timing of surgery controversial- often in 2 stages.
One commonly used plan involves early soft
palate repair at age 6 months, followed by hard
palate repair at age 6 years. Others involve
complete repair at a later age.
• Involvement with ENT, speech therapy, following
hearing tests, dental/orthodontic specialists,
social supports.
Undescended Testicle (cryptorchidism)
• Occurs in 3-4% of full term newborns
• More common in premature infants- transinguinal
migration occurs at 28-40 weeks gestation (under
hormonal control)
• Often the testicle will descend by the time the infant is
9 months old- prevalence is 1% at 1 year of age
• If there’s no descent by 1 year of age, this warrants
further workup
• One can ask the family to check at home in a warm
bath due to retractile testis (due to cremasteric reflex)
Causes

•

•
•
Increased incidence in prematurity
Increased risk with:
Small for gestational age
Low birth weight
Maternal exposure to estrogen early in pregnancy
Twin
Sibling with cryptorchidism
Conditions associated with low intra-abdominal
pressure
Cryptorchidism
Cryptorchidism
• Complications• Infertility (increased risk with time in abdomen)
• Increased risk for testicular cancer- approximately
40x normal
• If neither testicle palpable, endocrine and genetic
testing warranted to determine true sex
• Ultrasound may be helpful to identify the location
of the testicle- sometimes not present at all
• If partially descended, exam should be followed
closely to make sure fully descends
Treatments
• Often surgical (orchiopexy) though some medical
treatments have been tried including
testosterone and HCG
• Surgery performed by general surgeon or
urologist- usually between 6 and 12 months of
age
• Surgical correction many decrease the risk of
cancer though it is still significantly elevated.
• Another benefit of surgery is more easily
identifiable if tumor/mass. Also decreased
infertility.
Ear pits and tags
• There is an association between ear anomalies
and hearing loss. Audiologic evaluation is
recommended for any ear anomaly
• Multiple ear anomalies may suggest a kidney
problem as well as there is an association and
many syndromes contain anomalies in both
systems.
• Renal Ultrasound is not recommended if
isolated pit or tag
