How does cryosurgery work?
Cryosurgery is the use of extreme cold to destroy abnormal or diseased tissue. Cryosurgery uses medical grade gas to form a 6-10mm ice ball at the tip of a cryo-needle, which reaches temperatures as low as -50°C. The tip can be used to selectively destroy nerve tissue. This is done by causing extensive vascular damage to the nerve sheath capillaries. This then causes demyelination and degeneration of the axon. The epineurium and the perineurium remain intact, so the nerve will recover and regain normal sensation and function after treatment.
