Navicular head usually requires surgery for treatment. Navicular head, clinically known as cranial suture ossification, is due to a congenital developmental disorder, caused by early closure of the sagittal suture alone, and is the most common cranial deformity in premature closure of the cranial suture. Sagittal suture premature closure of the head to the lateral development is limited, that is, forward and backward expansion, occipital and frontal pole over-expansion, the result of the cranial vault is anterior and posterior elongation of the left and right narrowing so that the head is saddle-shaped deformity, shaped like a small boat and named. Infants’ brain develops fast, so in order to match the infant’s brain development speed, the fontanel will appear to increase in the first 6 months after birth. The sagittal suture of the skull in babies with navicular head closes prematurely, which will affect the development of the brain and ultimately the development of intelligence. Parents are advised to seek prompt medical attention once their babies are found to have navicular head, and it is best to have an operation to correct the condition before the age of 6 months to ensure the normal growth and development of the babies.
