Dolicocephalic head

Plagiocephaly is a general term for cranial asymmetry, derived from the Greek word roots, plagios, meaning "oblique, aslant" and kephalê, meaning "head." Pathogenically, plagiocephaly can be classified as synostotic, caused by abnormal sutural development, or deformational, caused by external forces acting on the cranium. Synostotic plagiocephaly usually requires surgical correction, whereas deformational plagiocephaly improves with crib positioning and, more predictably, with a molding helmet.
