The reason is congenital hypoplasia, which leads to the increase of bone mineral density at bilateral coronal suture in children. The skull base is shortened and transformed into the anterior cranial fossa, and the pterygoid of sphenoid bone is raised and tilted upward and backward, which deepens the temporal fossa and reduces the orbital volume. Check the details >> Examination and diagnosis show that a child can have obvious deformities within a few weeks after birth. The upper part of the frontal bone is high and wide, and the lower part is flat and sometimes concave. The upper part of the frontal bone is usually spherical and protrudes above the facial structure. The lower half contracts, pulling the nasal bone backward, and the bridge of the nose sinks. The nasopharyngeal cavity becomes smaller, sometimes the skull base and hard palate are often deformed, and children often have repeated upper respiratory tract infections. The ossified coronal suture touches a beaded bone nodule. View details >> Treatment and nursing are due to the fusion deformity of two or more cervical vertebrae, which is characterized by the reduction of the number of cervical vertebrae, the shortening of the neck, the limitation of head and neck movement, the patient's neck being shorter than normal, the hairline on the pillow being reduced, and the limitation of head movement. If there are no symptoms of nerve compression, conservative treatment such as skull traction or occipital-maxillofacial traction can be performed first, and plaster fixation can be performed on the head, neck and chest after the symptoms disappear. View details >> Preventive health care should avoid contact with the above possible pathogenic factors, and prenatal diagnosis and consultation should be made for school-age children and high-risk children. Generally speaking, the indications of prenatal diagnosis are: 1, elderly parents, mother >; 35 years old, father > 55 years old. 2. I have been born with congenital idiocy, and the risk of having 2 1- trisomy is 1~ 1.3%. 3. If parents are carriers of balanced translocation and t(Dq2 1q) translocation, the prevalence rate of children is 10~ 15% for females and 3 ~ 5% for males; T(2 1q2 1q) translocation is 100%, so sterilization is recommended. 4. One of the parents is chimera, which will increase the risk of having children. It is generally believed that chimera is hereditary and has a high recurrence rate. 5. Pregnant women with a family history of congenital idiocy and dermatoglyphic features of this disease. 6, habitual abortion. View details >>
