What disease does basal depression cause?

summary

This kind of basal depression, but never embarrassed to speak, because they think it is a disgrace. But in today's more and more pressure, there are more and more diseases. After the illness, it needs to be treated at the first time. What disease does basal depression cause?

What disease does basal depression cause?

Primary malformations are often associated with other malformations, such as flat skull base, midbrain aqueduct atresia, cerebellar tonsillar hernia, hydrocephalus, medulla oblongata and syringomyelia. The secondary clinical manifestations included osteomalacia, rickets, osteogenesis imperfecta and rheumatoid arthritis.

The purpose of operation is to relieve the compression of nerve tissue and restore the access of cerebrospinal fluid circulation. If necessary, the unstable atlantooccipital and cervical joints should be fixed. Because the operation is carried out in the medulla oblongata and the upper cervical spinal cord, and there are deformities in the medulla oblongata and the space is quite small, the risk of operation is much greater than that of general suboccipital decompression, and the operation is also difficult. The incidence of sudden respiratory arrest was 3% - 5%.

In some patients, medulla oblongata compression mainly comes from the anterior edge of foramen magnum on the ventral side, and the posterior displacement of odontoid process of axis, which is mainly manifested as pyramidal tract damage. In the sagittal position of MRI examination, it can be clearly seen that the compression comes from the ventral side, so only posterior occipital decompression has no obvious effect. Decompression can be performed through the anterior approach of neck or oropharynx to remove the anterior edge of foramen magnum, anterior arch of atlas and odontoid process. In order to prevent cerebrospinal fluid leakage, the dura mater should not be opened during the operation. For patients with ventral compression, good results can be achieved. For patients with poor stability of atlas, bone graft fusion should be performed after anterior approach.

matters needing attention

The purpose of treatment is to provide enough space for decompression. For the asymptomatic patients found by chance, they generally do not need treatment. They should be told to prevent head injury and excessive severe head flexion and extension. Cervical massage can aggravate the disease, which should be contraindicated. Patients with mild symptoms and stable condition can be followed up. Once progressive aggravation occurs, surgical treatment should be performed.
