2. What is the difference between chordotomy, neurectomy and rhizotomy?Chordotomy, rhizotomy and neurectomy are various procedures in which the nerves are cut or damaged to relieve pain. In chordotomy, a part of the spinal cord is cut; in rhizotomy, a dorsal nerve root is cut, while in neurectomy, a peripheral nerve is cut.
3. How long does the effect of the rhizotomy last?The pain relief obtained from rhizotomy usually lasts for around a couple of years to four years depending on the procedure. After this period, the nerves may grow back and the pain may return. You may have to undergo a repeat of the same procedure or a different procedure at such times.
