Scaphocephaly: A long, narrow head is common with midline "sagittal" synostosis, when the suture extending from front to back over the top of the head fuses too soon. Some of the more commonly seen types of head shapes, with the involved sutures, include: The baby's particular head shape will also point to the specific suture involved. Skull bone sutures that fused too soon may be felt as ridges that run along various parts of the baby's head. Plagiocephaly is more common on the right side, and also shows up more often in male infants. In the case of positional plagiocephaly, the two fingers will not line up opposite each other. Your doctor may gently place a finger in each ear and note the position of their fingers relative to each other as observed from above the baby's head. One side of the head may appear to be pushed forward, with the back of the head being flattened, the ear moved slightly forward, and the forehead pushed slightly forward on the same side compared with the opposite side. One sign a baby's uneven head shape was caused by position alone is the classic parallelogram shape. These observations and information will help differentiate positional plagiocephaly (caused by simple pressure in one area) from craniosynostosis (caused by bony fusion). This may be easier when the baby's hair is wet. They will also conduct careful examinations, looking at the baby's head and face from several different angles as they search for raised or flattened areas and noting any asymmetry. To help determine what's causing a baby's uneven head shape, pediatricians will talk with parents to piece together a developmental and family history. Depending on which of the sutures close early, and where they are located, the shape of the skull, brain and face can become distorted. With craniosynostosis, two or more bones fuse together before a baby's brain growth is completed-sometimes even before birth. They also allow the skull to expand rapidly during the first year of life, when the baby's brain more than doubles in size. The soft, flexible spaces between a baby's six separate bones of the head, called "sutures," do more than help the head squeeze through the birth canal. It is estimated that about 1 in every 2,000 U.S. This rare condition, called craniosynostosis, may require surgery both to correct the head shape abnormality and in some cases to give the baby's brain room it needs to grow. Less commonly, an uneven head shape happens when the bones of the skull fuse together too soon. If the deformation is moderate or severe and not responding to position changes, helmet therapy may help. Flat spots may also improve, especially with position changes and extra While an asymmetrical head shape is a common cause of concern for new parents, a baby's head typically rounds out after birth. Because the individual bones of a newborn's skull aren't yet fused together, pressure from resting in the same position can cause an infant's head to be misshapen. It is not unusual for a baby's head to look a little lopsided.
