oxycephaly

 [ok-se-sef´ah-le]
a condition in which the top of the skull is pointed or conical owing to premature closure of the coronal and lambdoid sutures. adj., adj oxycephal´ic.

oxycephaly

[ok′sisef′əlē]
Etymology: Gk, oxys + kephale, head
a congenital malformation of the skull in which premature closure of the coronal and sagittal sutures results in accelerated upward growth of the head, giving it a long, narrow appearance with the top pointed or conic. Also called acrocephaly, hypsicephaly, oxycephalia, steeple head, tower head, tower skull, turricephaly. See also craniostenosis. oxycephalous, adj., oxycephalus, n.

craniosynostosis type 1

A condition (OMIM:123100) characterised by premature fusion of one or more cranial sutures, resulting in an abnormal head shape.

Molecular pathology
Defects of TWIST1, which encodes a basic helix-loop-helix (bHLH) transcription factor, cause craniosynostosis type 1.

ox·y·ceph·a·ly

(ok'sē-sef'ă-lē)
A type of craniosynostosis in which there is premature closure of the lambdoid and coronal sutures, resulting in an abnormally high, peaked, or cone-shaped cranium.
Synonym(s): acrocephaly, acrocephalia.
[G. oxys, pointed, + kephalē, head]

oxycephaly

A skull abnormality causing the head to assume a conical or peaked appearance. Oxycephaly is due to premature closure of the irregular junctions on the side of the skull between the bones of the vault (the coronal or lambdoidal sutures). Also known as tower head.

oxycephaly

premature closure of lambdoidal and coronal sutures, causing abnormally high, peaked, or conically shaped skull; characteristic of Carpenter's and Apert's syndromes

ox·y·ceph·a·ly

(ok'sē-sef'ă-lē)
A type of craniosynostosis in which there is premature closure of the lambdoid and coronal sutures, resulting in an abnormally high, peaked, or cone-shaped cranium.
Synonym(s): acrocephaly, acrocephalia.
[G. oxys, pointed, + kephalē, head]

oxycephaly (ok´sēsef´əlē),

n, a high conical crown resulting from early closure of sutures and disturbed cranial development. Also called
steeple head.

oxycephaly

congenital condition in which the top of the head is pointed due to premature closure of the coronal and lambdoid sutures. Called also acrocephaly, acrocephalia.
