Brachycephaly, similar to plagiocephaly, is when a baby develops a flat spot on the head. However, in brachycephalic head shapes, the flattening occurs symmetrically to the back of the skull. This flattening causes the head to become shorter …

Brachycephaly (derived from the Ancient Greek βραχύς, 'short' and κεφαλή, 'head') is the shape of a skull shorter than average in its species. It is perceived as a cosmetically desirable trait in some domesticated dog and cat breeds, notably the pug and Persian, and can be normal or abnormal in other animal species.

2024年9月10日 · Positional brachycephaly or plagiocephaly is the most common head-shape abnormality, affecting between 20% and 50% of infants in the United States. Approximately 20% of cases of positional plagiocephaly may be observed at the time of birth.

What causes plagiocephaly and brachycephaly? The skull is made up of plates of bone that strengthen and join together as a child gets older. A young baby's skull is still relatively soft and can change shape if there's constant pressure on a particular part of their head. Reasons why this may happen include:

The most common features describing a brachycephaly are a very wide head shape, sometimes wider than it is long from front to back. The head shape can be quite pushed up and high at the back with a slope down to the forehead and a prominent brow.

2024年8月22日 · Brachycephaly refers to a calvarial shape where the bi-parietal diameter to fronto-occipital diameter approaches the 95 th percentile. It can result from a craniosynostosis involving the coronal and lambdoid sutures.

Brachycephaly is a specific type of head shape change characterized by flattening at the back of the head. Unlike plagiocephaly (which involves asymmetry), brachycephaly occurs when the infant frequently rests the back of their head on a flat surface.
