The number of years of survival after surgery for spinal cord cavitation, as long as the surgery goes smoothly, the postoperative recovery is also smooth, there are no complications or sequelae, and the person is able to take care of himself, basically there is no special impact on the later stage and it will not affect the life expectancy. It is not a tumor, nor is it a cerebrovascular disease, nor does it differentiate between recurrence, benign, and other phenomena, but it is mainly due to pressure changes that cause the manifestation of spinal cord cavitation. On the CT and MRI films, it shows a tube-like cavity, so it is called spinal cavitation. As long as the surgery is done, which goes very well, and the normal anatomical tissue structure is restored, the spinal cord cavitation can disappear at a later stage. The normal form can be restored and there is no special impact on life. However, complications occurring after surgery, such as choking and coughing of swallowing function, hemiplegia of limbs, paraplegia, etc., can be excluded, and if these symptoms occur, they may have an impact on life, but there is no special impact if there is simple spinal cord cavitation.
