What is Microcephaly?

Microcephaly can be distinguished from true microcephaly, which is relative to microcephaly. True microcephaly is mostly caused by an autosomal aberration or the fetus, especially in early pregnancy, due to radiation exposure or intrauterine infection. It shows that the brain Too small, or no brain gyrus, brain development is significantly delayed, often stop progressing in the fetus in the first 3-5 months, the patient's head is small and pointed, flat forehead, head circumference smaller than the chest turn, the maximum does not exceed 43 cm, the smallest Can be below 25 cm, brain weight below 900 grams, forehead and occipital region are usually flat, the anterior condyle is closed early, all or part of the bone suture is closed prematurely, physical and intellectual development is retarded, language and behavioral developmental disorders, and some patients have Convulsions, muscle tonic lymphatics, and even spastic paralysis. The preplanned events vary depending on the degree of brain dysplasia. Acupuncture treatment can receive a certain effect. Relative microcephaly is also called pseudocephaly due to inflammation. The brain Brain damage and brain atrophy caused by vascular injury, the reduction of head circumference is lighter than that of true microcephaly.

Explanation of microcephaly

Microcephaly can be distinguished from true microcephaly, which is relative to microcephaly. True microcephaly is mostly caused by an autosomal aberration or the fetus, especially in early pregnancy, due to radiation exposure or intrauterine infection. It shows that the brain Too small, or no brain gyrus, brain development is significantly delayed, often stop progressing in the fetus in the first 3-5 months, the patient's head is small and pointed, flat forehead, head circumference smaller than the chest turn, the maximum does not exceed 43 cm, the smallest Can be below 25 cm, brain weight below 900 grams, forehead and occipital region are usually flat, the anterior condyle is closed early, all or part of the bone suture is closed prematurely, physical and intellectual development is retarded, language and behavioral developmental disorders, and some patients have Convulsions, muscle tonic lymphatics, and even spastic paralysis. The preplanned events vary depending on the degree of brain dysplasia. Acupuncture treatment can receive a certain effect. Relative microcephaly is also called pseudocephaly due to inflammation. The brain Brain damage and brain atrophy caused by vascular injury, the reduction of head circumference is lighter than that of true microcephaly.

Microcephaly symptoms

The main manifestation of this disease is that after the development of the brain, the brain weight is significantly lighter than normal, and the brain gyrus is too small or no brain gyrus at all. The brain's development is significantly retarded, and it stops developing even in the third to fifth months of life. As a result, the top of the child's head became small and pointed, the nose bridge was depressed, the ears were large, the forehead was retracted, the forehead was narrow and the head circumference was extremely small, the maximum was less than 42 cm. The forehead and occipital area of the sick child were flat, and the cardia and bone suture were closed early. Physical development was significantly abnormal and mental development was significantly retarded. Some children even have convulsions, stiff limbs, slow movements of hands and feet, and paralysis.

Microcephaly examination treatment

Treatment of this disease should be examined by skull photographs and CT. For patients with elevated intracranial pressure, surgery should be performed as soon as possible. For children with premature closure of bone sutures, neurosurgery can be used to achieve certain results.

Microcephaly is mainly surgical treatment, the purpose is to expand the cranial cavity, relieve intracranial hypertension, so that the compressed brain tissue and cranial nerves develop and grow.

There are two methods of surgical treatment, one is to remove prematurely closed bone sutures, and then choose new ones, and the other is to remove large bones to reduce stress and facilitate brain development.

The earlier the operation, the better. The prognosis is better within 6 months after the operation. Once the optic nerve atrophy and mental retardation occur, the function is not easy to recover even after the operation.
