Cryotherapy & Wart Excision Procedures
Targeted procedures to clear stubborn plantar warts when home treatments have failed.
What Are Cryotherapy & Wart Excision?
Plantar warts are caused by the human papillomavirus (HPV) and can be remarkably persistent. Over-the-counter salicylic acid kits and home freeze sprays often reduce the surface bulk but fail to clear the viral tissue beneath the skin, leading to recurrence.
Two in-clinic procedures address this directly:
- Cryotherapy — controlled freezing with liquid nitrogen to destroy wart tissue
- Wart Excision — surgical removal of the wart under local anaesthetic
The right choice depends on the wart’s size, location, depth, and your prior treatment history. Both are performed in clinic with minimal downtime.
Who These Procedures Help
Painful Plantar Warts
Warts causing pressure pain when walking
Mosaic Warts
Clusters of small warts grouped together
Recurrent Warts
Warts returning after home treatment
Treatment-Resistant Warts
Warts unresponsive to salicylic acid
High-Risk Patients
Diabetic or immunocompromised individuals needing professional care
Spotlight: Cryotherapy vs Wart Excision —
How We Decide
Patients often ask which treatment is best. The answer depends on the wart, not a personal preference.
Factor
Cryotherapy
Wart Excision
How it works
Controlled freezing destroys wart tissue
Surgical removal under local anaesthetic
Sessions needed
3 to 6, spaced 2 to 4 weeks apart
Usually a single visit
Discomfort level
Brief stinging during freezing
Numb during procedure; mild post-procedure soreness
Recovery time
Walk immediately; mild blistering for a few days
A few days of reduced walking; dressing changes
Scarring risk
Very low
Very low
Best for
Small to medium warts, multiple lesions, children
Large, deep, or resistant warts that have failed cryotherapy
Where appropriate, cryotherapy is tried first because it is less invasive. Excision is reserved for warts that prove resistant or are too deep for freezing to penetrate effectively.

How Cryotherapy Works
The wart is examined to confirm it is viral and not a corn, callus, or other lesion.
A controlled freeze is applied directly to the wart, typically with a probe or spray, to destroy the affected tissue.
A blister forms over the treated area in the days following the session. This is part of the immune response that clears the wart.
Treatment is repeated every 2 to 4 weeks until clearance, usually across 3 to 6 sessions.
How Wart Excision Works
The area is numbed before any incision is made.
The wart and its base are removed in a single procedure using a sterile technique.
The site is dressed and offloaded with padding or a postoperative shoe if needed.
A follow-up visit checks healing progress and addresses any signs of recurrence.
Why Professional Treatment Matters
- Home freeze kits rarely reach the depth required to destroy viral tissue
- Salicylic acid often macerates surrounding healthy skin and increases infection risk
- DIY cutting risks bleeding, infection, and unnecessary scarring
- Accurate diagnosis is critical, because warts, corns, and certain skin cancers can look similar
- Particularly important for diabetic or immunocompromised patients, where home treatment can trigger ulceration
A Real-World Note on Why This Matters
In a Cochrane systematic review of cutaneous wart treatments (Kwok et al., Cochrane Database of Systematic Reviews 2012), cryotherapy with liquid nitrogen demonstrated higher clearance rates than placebo and was superior to many home treatments, particularly when applied at appropriate intervals. The intervals matter: applying it too soon or too late reduces efficacy, which is one reason in-clinic timing outperforms home kits.
