Head shape abnormalities refer to irregularities in the size or shape of a person's head. These can occur due to various factors, including genetic conditions, environmental influences, or developmental issues during pregnancy. Common types include plagiocephaly, where one side of the head is flattened, and brachycephaly, characterized by a wider, shorter head shape. These abnormalities can affect both infants and adults, and they may lead to concerns about appearance or potential developmental issues. Treatment options vary depending on the severity and underlying cause, ranging from physical therapy to the use of helmets designed to reshape the head during infancy.
