Vitiligo Surgery: Types, Candidates and What to Expect
Vitiligo is a condition in which areas of the skin lose their pigment because of loss or dysfunction of melanocytes, the cells responsible for producing melanin. While many patients respond to medical treatments such as topical medications and phototherapy, some stable, localized vitiligo patches may benefit from vitiligo surgery when satisfactory re-pigmentation has not been achieved with medical treatment.
What is vitiligo surgery?
Vitiligo surgery is a group of procedures that transfer pigment-producing cells or pigmented skin from a healthy area of the patient's body to a depigmented vitiligo patch. The aim is to restore pigmentation in areas that have remained resistant to conventional treatment.
Surgery is not suitable for every person with vitiligo. Disease stability, size and location of the patches, type of vitiligo, response to previous treatment and the presence of suitable donor skin all influence whether surgery is appropriate.
Why is stability of vitiligo important?
This is one of the most important factors before considering vitiligo surgery.
Stable vitiligo generally means that there has been no significant development of new patches or enlargement of existing patches for a prolonged period. Traditional Indian guidelines have suggested absence of progression for approximately one year as a practical definition of stability, although there is no universally accepted single definition.
Surgery performed while vitiligo is actively progressing may have a higher risk of poor or incomplete re-pigmentation and recurrence. Current recommendations therefore generally reserve surgery for stable, localized or recalcitrant vitiligo.
Your dermatologist may assess previous photographs, history of new or enlarging patches and other clinical features to determine stability.
Types of vitiligo surgery
Vitiligo surgeries can broadly be divided into tissue grafting procedures and cellular transplantation procedures.
- Punch grafting
Small pieces of normally pigmented skin are harvested from a donor site and placed into small prepared areas within the vitiligo patch.
It can be useful for selected small, stable patches, but the possibility of a cobblestone appearance or uneven pigmentation needs to be considered.
- Split-thickness skin grafting
A thin layer of normally pigmented skin is harvested from a donor site and transplanted onto the depigmented area.
This technique can be useful for appropriately selected stable vitiligo, particularly when larger areas need to be treated.
- Suction blister grafting
A blister is created on normally pigmented donor skin using controlled suction. The epidermal roof of the blister, containing melanocytes, is then transferred to the prepared vitiligo patch.
This technique avoids harvesting a thicker piece of skin and can provide good cosmetic results in selected patients.
- Non-cultured melanocyte-keratinocyte transplantation
This is a cellular grafting technique. A small sample of normally pigmented skin is taken from a donor site and processed to obtain a suspension containing melanocytes and keratinocytes. The cell suspension is then transferred to a prepared vitiligo area.
One advantage is that a relatively small donor area can potentially be used to treat a comparatively larger recipient area. Non-cultured melanocyte-keratinocyte transplantation is an established option for appropriately selected patients with stable vitiligo who have not responded adequately to medical treatment.
- Cultured melanocyte transplantation
In this approach, melanocytes obtained from a small donor skin sample are expanded in a laboratory before being transplanted to the vitiligo patches.
Availability, expertise and cost can vary between centres, so this procedure is not routinely available everywhere.
Who is the best candidate for vitiligo surgery?
The ideal candidate is generally someone with:
Stable vitiligo.
No significant new patches or enlargement of existing patches for an appropriate period.
Limited, localized or resistant patches.
Inadequate response to appropriate medical treatment.
A suitable donor site with normally pigmented skin.
Realistic expectations regarding the degree and speed of re-pigmentation.
Surgery can be particularly useful when a patient has a few persistent patches that are cosmetically troublesome despite appropriate medical treatment.
When is vitiligo surgery usually avoided?
Surgery is generally not the first choice when vitiligo is actively progressing. Patients with frequent new patches or enlargement of existing lesions may need treatment aimed at controlling disease activity before surgery is considered.
Surgery may also be unsuitable in people with a tendency to develop problematic scars or when the location, extent or characteristics of the patches make a surgical approach unlikely to provide a satisfactory result.
Does vitiligo surgery cure vitiligo?
No. Vitiligo surgery does not cure the underlying autoimmune tendency.
It is a method of re-pigmenting selected stable patches. Even after successful re-pigmentation, ongoing dermatological follow-up may be important because vitiligo can potentially become active again.
Re-pigmentation is also not instantaneous. Depending on the technique and individual factors, colour may develop gradually over several months; some patients may continue to develop pigmentation for up to a year after cellular transplantation.
Take-home message
Vitiligo surgery is not for every vitiligo patient. The most important requirement is usually stable disease, particularly when patches are localized and have remained resistant to medical treatment.
At DermcareMD Skin and Hair Clinic by Dr Neha Athalye, Kothrud, Pune, we assess each patient individually, carefully evaluating the stability, extent and location of vitiligo, previous treatment response and suitability for surgery. Treatment options are then optimised according to the patient's specific needs, with the aim of achieving the best possible re-pigmentation and cosmetic outcome.
