Cloverleaf skull, syndrome

[MIM 148 800, 600 775]

(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
