Which statement best describes the recommended approach for applying cryotherapy to small facial lesions?

• A. No anesthesia; load the cryogen cartridge into the cryoprobe, disinfect; apply gel to optimize contact; extend 2-3 mm beyond border
• B. Dip the cryoprobe tip in liquid nitrogen and apply directly to the lesion
• C. Use cryospray for all small facial lesions
• D. Apply topical anesthetic before freezing

Answer: (A)

The key idea is to treat small facial lesions with a controlled, precise cryotherapy technique that ensures complete destruction while protecting surrounding skin. Using a cryoprobe loaded with cryogen and kept clean creates a direct, targeted freeze. Placing a gel between the probe and skin improves thermal contact, reducing air gaps that can limit cooling and risk uneven destruction. Extending the frozen area 2–3 mm beyond the visible border helps cover any subclinical extension of the lesion, lowering the chance of recurrence.

Not using anesthesia aligns with the reality that this quick procedure is usually well tolerated and that anesthesia can interfere with the probe’s contact or obscure borders, potentially altering the precision of the treatment. Disfavored alternatives include dipping the probe into liquid nitrogen, which gives inconsistent cooling and depth; cryospray, which offers poor control for small, delicate facial lesions; and applying topical anesthetic before freezing, which can affect tissue properties and margin assessment.
