plagiocephaly
Pronunciation: play-jee-oh-SEFF-ah-lee
Asymmetrical flattening of the skull, often caused by positional factors during infancy.
Full Definition
Plagiocephaly is a condition characterized by asymmetrical distortion of the skull, resulting in a parallelogram-shaped head when viewed from above. It can be positional (most common, caused by external forces such as sleeping position) or synostotic (caused by premature fusion of cranial sutures). Positional plagiocephaly has increased since the Back to Sleep campaign began in the 1990s. Treatment may include repositioning techniques, physical therapy, or in severe cases, cranial molding helmets. Early recognition and intervention are important for optimal cosmetic and functional outcomes.
Usage
Usage note: Distinguish from other cranial shape abnormalities like brachycephaly (widening) or scaphocephaly (elongation).
