Cryotherapy
Cryotherapy for Skin Conditions: Overview, Uses, and Effectiveness
What is Cryotherapy?
Cryotherapy (also known as cryosurgery) is a medical treatment that uses extreme cold, typically liquid nitrogen, to destroy abnormal or diseased skin tissue. It is a minimally invasive, efficient, and widely used dermatologic procedure often performed on an outpatient basis.
Mechanism of Action
- Cryotherapy freezes the targeted skin cells, causing ice crystal formation, cellular dehydration, and disruption of cellular structures.
- This leads to cell death and sloughing off of the treated tissue, followed by regeneration of healthy skin.
Common Skin Conditions Treated
- Benign lesions: Warts, skin tags, seborrheic keratoses, cherry angiomas, molluscum contagiosum.
- Precancerous lesions: Actinic keratoses (AKs) with cure rates ranging from 39% up to 83% depending on freeze time and technique.
- Superficial skin cancers: Selected basal cell carcinomas and squamous cell carcinomas.
- Pigmented lesions: Solar lentigines (age spots), melasma (less common compared to topical therapies).
- Other dermatologic conditions: Molluscum, superficial fungal infections, and some inflammatory skin diseases due to cryotherapy’s anti-inflammatory effects.
Benefits of Cryotherapy
- Rapid and precise treatment with minimal damage to surrounding healthy tissue.
- Minimal downtime, with most patients resuming normal activities shortly after.
- Typically results in low risk of scarring or pigmentary changes when performed correctly.
- Cost-effective and well-tolerated with mild discomfort during the procedure.
- Can be repeated for thick or resistant lesions.
Procedure Details
- Liquid nitrogen is applied by spray, swab, or probe to the lesion.
- Freeze times vary by lesion, typically from 5 to 30 seconds per freeze-thaw cycle.
- One or multiple freeze-thaw cycles are performed depending on lesion thickness and response.
- Treatments are often scheduled 4-6 weeks apart until resolution.
Side Effects and Considerations
- Temporary redness, blistering, crusting, and peeling post-treatment.
- Hypopigmentation or hyperpigmentation, especially in darker skin types or with aggressive treatment.
- Rarely, scarring or secondary infection may occur.
- Not recommended for suspicious melanocytic lesions without biopsy confirmation.
Summary
Cryotherapy is a highly effective, versatile, and widely used treatment for many benign, precancerous, and select malignant skin conditions. Proper patient selection, technique, and follow-up optimize safety and outcomes.
