Which is a possible complication of cryotherapy?

• A. Permanent nerve damage
• B. Systemic infection
• C. Healthy tissue damage
• D. Hair regrowth

Answer: (C)

Cryotherapy aims to freeze only the abnormal tissue, but precision is essential. If the freeze extends into surrounding healthy tissue, those normal cells can be damaged by ice crystal formation and disrupted blood flow, leading to tissue death near the treated area. This collateral injury can show up as blistering, ulceration, scarring, or pigment changes—clear examples of a possible complication. Systemic infection isn’t expected with localized, typically aseptic procedures. Permanent nerve damage is possible only if the freezing is unusually deep or close to nerves, making it less likely as a general complication. Hair regrowth isn’t a complication arising from tissue injury itself, though hair follicles in the treated zone may be affected differently depending on depth.
