1. What are the types of spina bifida? Spina bifida is divided into dominant spina bifida and recessive spina bifida in terms of broad categories. The main types of spina bifida are spondylolisthesis, spinal cord spondylolisthesis with lipoma, and spinal cord exstrophy. Occult spina bifida can be end filament embolism, intramedullary lipoma, spinal longitudinal bifida, intradural dermatomal cyst, and other types. 2. What is the difference between the symptoms of recessive spina bifida and overt spina bifida? Can they be clearly distinguished by visual observation alone? Occult spina bifida has no obvious abnormalities in appearance and some symptoms are not obvious or are asymptomatic, so it is not easy to detect. It is possible to distinguish it with the naked eye, but it does not mean that occult spina bifida is not as serious as dominant spina bifida, because occult spina bifida is not easily detected and sometimes it is easy to miss the diagnosis and delay the treatment, or even develop serious symptoms or even sequelae. 3.Do I need to treat recessive spina bifida before symptoms appear? Generally speaking, parents who do not have symptoms do not want to undergo surgery and do not feel the need for treatment. However, some children do not have symptoms, but the MRI has shown spinal cord embolism, then this requires early surgery, so as not to wait for the symptoms of spinal cord injury and then surgery and miss the best treatment time. 4. Is there no need to pay special attention to patients with occult spina bifida? What do I need to pay special attention to in my daily life? If there is no problem with MRI, then there is no need to pay special attention to patients with occult spina bifida. However, children who have problems with MRI need special attention. They should pay attention to changes in their bowel movements and the function of their lower extremities, and they should see a specialist immediately if there are any abnormalities. 5.What are the symptoms of occult spina bifida that mean the disease is getting worse? What should I do at this time? If there are changes in urination and defecation such as weakness of the lower limbs, constipation, feces, dribbling, leakage, or loss of urine, it is possible that the disease has worsened and you should see a specialist as soon as possible.
