Fontanelle closed late

Introduction There are two parts of the newborn's skull that have not healed, called the anterior and posterior sacral. The anterior cardia is a diamond-shaped gap formed by the forehead and the parietal bone. It is about 1.5-2 cm in size at birth. After birth, the anterior iliac crest grows larger with the head circumference, and gradually becomes ossified after 6 months, and closes when it is about 1-1.5 years old. The posterior malleolus is a gap between the two parietal bones and the occipital bone, which is triangular, and the posterior malleolus is usually closed within 3 months after birth. If the anterior iliac crest closure time exceeds 6 months after birth and the iliac crest closure time exceeds 3 months, the cardia closure is late. Tuen Mun (xìn mén) means that the baby has two skylights without bones at the top of his birth, which is medically known as the door. The posterior cardia is usually closed 3 months after birth, and the front door is closed until 1 year and a half. People often say that "skylight" or "the door" mainly refers to the front door.

Cause

Late closure of the cardia is more common in infants with rickets, hydrocephalus, stagnation and overgrowth, and vitamin D and calcium deficiency can cause.

The late closure of the card, mainly refers to the baby has been 18 months, but the front door has not been closed, more common in rickets, stay a small disease.

Late in the cardia, a small number of cases caused by hydrocephalus or other causes of increased intracranial pressure, should go to the hospital for further examination.

The main content of skull development is measured early and late in the closure of the cardia. Closing too early or too late is a manifestation of abnormal growth and development. Chinese medicine refers to the sacral sacral sacral filling, the sacral depression is called the depression, and the sacral sac is called the sacral sac. Late closure of the cardia is more common in infants with rickets, hydrocephalus, stagnation and overgrowth.

The tips on the head of infants are usually closed in 12-18 months. The closure of the cardia is a window reflecting the development of the brain. If closed before 6 months, the child may have microcephaly or brain hypoplasia, still after 18 months. It is too late to be closed. Such a child may have hydrocephalus, rickets and ailments; the bulge of the sputum indicates an increase in intracranial pressure. This child may have meningitis, encephalitis and vitamin A poisoning; Children may be due to dehydration and malnutrition. If the trick is closed earlier, but as long as the head circumference is still long, don't worry. If the cardia is found to be abnormally closed, the child should be taken to the hospital for further examination.

There are two parts of the newborn's skull that have not healed, called the anterior and posterior sacral. The anterior cardia is a diamond-shaped gap formed by the forehead and the parietal bone. It is about 1.5-2 cm in size at birth. After birth, the anterior iliac crest grows larger with the head circumference, and gradually becomes ossified after 6 months, and closes when it is about 1-1.5 years old. The posterior malleolus is a gap between the two parietal bones and the occipital bone, which is triangular, and the posterior malleolus is usually closed within 3 months after birth. If the anterior iliac crest closure time exceeds 6 months after birth and the iliac crest closure time exceeds 3 months, the cardia closure is late.

Differential diagnosis

Tricks beating: The beating of the cardia is that the baby's cardia is not closed. The posterior condyle is usually closed within three months after birth. The anterior iliac crest is closed approximately 1 to 1.5 years after birth. Since there is no hard skull cover at the cardia, care should be taken to prevent damage to the brain.

Anterior sag: It is characterized by sag of the anterior sacral sag, mostly accompanied by eye socket depression, and decreased urine output. This symptom occurs in children and should be considered for dehydration. Generally, according to the clinical manifestations such as anterior hernia, eye socket, skin elasticity, circulation and urine volume, it can be judged whether or not dehydration, and the degree of dehydration can be estimated.

Delay of anterior iliac crest closure: thinning of the skull, separation of cranial sutures, and delayed or enlarged anterior and posterior iliac crest are common clinical symptoms of hydrocephalus.

The anterior iliac crest is full, indicating an increase in intracranial pressure, common in children with meningitis and hydrocephalus. Headache, vomiting, and papilledema are typical signs of increased intracranial pressure. The triad is called a triad of increased intracranial pressure. Because the skull is not closed, the cranial suture is separated when the intracranial pressure is increased, so there is no headache. Pediatric patients often have only recurrent vomiting as their only symptom.
