Nerve root sheath cysts can only be cured by surgical treatment. Nerve root sheath cysts are benign lesions, and patients can have symptoms of nerve root compression, such as numbness in the hands that occurs with cysts in the cervical nerve root sheath, and numbness and weakness in the lower extremities that occurs with nerve root sheath cysts in the lumbar spine. The nerve root sheath cysts need to be completely removed during surgery. The posterior lamina can be cut open through posterior surgery to expose the nerve root canal, and then the nerve root sheath cysts can be completely removed. Of course, nerve root sheath cysts in the lumbar spine can be operated through a discoscope, which is a minimally invasive surgical operation. The cyst of the nerve root sheath is exposed through the intervertebral foramen approach and then completely peeled off, and the surgical result is very good.
