Cloverleaf skull, syndrome
|
(Kleeblattschaedel syndrome)
Very rare. Craniosynostosis involving the coronal and lambdoidal sutures producing a trilobe cloverleaf-shaped skull with:
- exophthalmos and risk of lagophthalmos
- a flattened nose
- midface hypoplasia
- hydrocephalus by stenosis of aqueduct of Sylvius
- malformations of the brain or cerebellum
This syndrome can be observed alone or, more often, in association with:
- the acrocephalosyndactylies: Crouzon (7 %), Pfeiffer or Carpenter syndrome
- thanatophoric dwarfism type II ,
- Jeune's syndrome
- camptomelic dwarfism
- the sequence of uterine rupture
- amniotic bands
Anesthetic implications:
obstructive apneas; difficult manual ventilation by mask and difficult intubation; intracranial hypertension
