plagiocephaly

(pla?je-o-sef'a-le) [ plagio- + -cephaly]
A malformation of the skull producing the appearance of a twisted and lopsided head, caused by irregular closure of the cranial sutures.

deformational plagiocephaly

Plagiocephaly on one side the skull of an infant, usually after repeatedly sleeping in a single position, e.g. on the infant's back, to prevent SIDS.

It can usually be treated nonoperatively by repositioning the developing infant frequently, or by having the child wear a protective, adjustable helmet while resting.
