Minimally invasive treatment is not a complete cure for spinal cord cavernous disease because spinal cord cavernous disease occurs as a result of certain bony deformities and neural adhesions. For example, spinal cord cavities in the cervical cord are often caused by malformations of the occipital foramen magnum combined with subcerebellar herniation of the cerebellar tonsils, which results in spinal cord cavernosities. In the sacral cord, it is often due to tethering of the spinal cord. In both cases, there is no cure through minimally invasive surgery alone, but rather through open surgery to remove the malformation of the occipital foramen magnum and to open it up appropriately. For the sacral medulla oblongata, certain microscopic techniques are needed to separate the nerves so that spinal cord cavernous disease can be better treated. Minimally invasive techniques do not allow for a very good visualization, and in many cases they can only alleviate the symptoms rather than treating the root cause. Therefore, it is recommended that spinal cord cavernous disease should be treated with open surgery.
