The main purpose of nerve release surgery is to release the nerve from the surrounding scar tissue and the scar tissue within the nerve epithelium, to relieve the nerve fibers from direct pressure, to improve blood circulation to the nerve, and to promote recovery of nerve function. The treatment may vary for different diseases, for example, for carpal tunnel syndrome, the general steps of nerve release surgery are: 1) anesthesia; 2) incision, once the incision is formed, the peripheral nerve needs to be exposed; 3) nerve release, the general method is to first free the median nerve, explore and remove all nerve causing factors on the deep side of the median nerve and the base of the carpal tunnel. If necessary, the epineurium can be incised under the surgical microscope, and external and internal nerve release can be performed until all the adherent nerves are completely separated.4. Suturing is performed.
