The shape and size of the skull vary obviously with people, race, sex and age. The size of the skull is often expressed by the numerical values of the anterior diameter, transverse diameter and height diameter of the skull.
The navicular head is a kind of craniofacial stenosis, which is often caused by premature closure of sagittal suture of skull, resulting in craniofacial deformity. After the child is born, it can be found that the skull has a long anterior and posterior diameter, a short transverse diameter, a flat forehead, a disappearing eyebrow arch and a protruding jaw. X-ray examination showed that the skull was thin and had finger indentation.
The top of the boat-shaped head is narrow in the middle and wide on both sides, which looks like a boat. The head is long, the occipital bone is prominent, the occipital protuberance is obvious, the forehead of the navicular head is wide, the forehead is prominent and the hairline is low.
The features of the navicular head and face are obvious, with prominent upper and lower jaws, thick lips, big nose and wide chin. The eyes of the navicular head are usually prominent and the eye distance is wide. People with boat heads may have problems in intelligence, language and behavior development, but this is not necessarily the case.
Causes of navicular head formation and matters needing attention in treatment;
1. Fetal compression: If the pregnant woman's abdominal space is limited and the fetal head is compressed for a long time, it will affect the normal development of the skull and lead to the formation of the navicular head. Genetic factors: the navicular head is hereditary. If there are patients with navicular head in the family, the risk of the next generation of navicular head is relatively high.
2. Head trauma: Head trauma may lead to poor blood supply to the skull, affect the normal development of the skull, and then trigger the navicular head. Rickets: Severe rickets may cause the skull to soften and deform, affect the normal development of the skull, and then lead to the navicular head.
3. Precautions for treatment of navicular head:
Seek medical attention in time. The navicular head is a disease that needs medical treatment. Parents are advised to seek medical attention as soon as they find that their baby has a navicular head, and it is best to perform surgical correction 6 months ago. Prevent complications. Patients with navicular head may have problems in intelligence, language and behavior development, and these complications need active prevention and treatment.
Adjust your sleeping position. If the baby's sagittal suture is closed prematurely, it may affect the lateral development of the skull. If the symptoms are not obvious, parents are advised to let the baby sleep on his back, which can put some pressure on the skull and help improve the external performance.
Supplement nutrition. Under the guidance of doctors, proper supplementation of vitamin D and calcium will help to improve the symptoms of navicular head. Surgical treatment. For severe navicular head, surgery is needed. It is recommended that the child be operated before 1 year old to ensure the normal growth and development of the baby.
