Skull shape abnormalities refer to irregularities in the shape or structure of the skull. These can occur due to genetic factors, environmental influences, or medical conditions. Common types include plagiocephaly, where one side of the head is flattened, and brachycephaly, characterized by a broad, short skull. These abnormalities can affect brain development and facial appearance. Diagnosis typically involves physical examination and imaging techniques like CT scans or MRI. Treatment options may include helmet therapy for infants or surgical intervention in more severe cases to correct the shape and support normal growth.
