VITILIGO SURGERY

image

SUMMARY

  • Vitiligo surgery is an effective treatment modality in patients with stable disease who have failed medical management (except for focal and segmental vitiligo, in which surgery is a first-line option), and do not have perioral or distal fingertip involvement.

  • Surgical techniques in vitiligo are broadly classified as either tissue or cellular grafts.

image Beginner Tips

  • Indicators of a favorable response include stable disease, focal and segmental vitiligo, and facial, neck, and truncal involvement.

  • Indicators of an unfavorable response include unstable disease, nonsegmental vitiligo, isolated scalp leukotrichia, and lesions affecting the extremities, distal fingertips, periorificial areas, and joints.

  • STSG is the most effective surgical technique for establishing repigmentation in small patches of vitiligo, but it does have limitations.

  • For larger patches of vitiligo, NCES is the most effective treatment option, with the largest number of supporting clinical trials available.

  • Adjuvant treatments such as topical immunomodulators, oral corticosteroids, oral antioxidants, phototherapy, and additional surgeries may be necessary after vitiligo surgery to optimize treatment outcomes.

image Don’t Forget!

  • The size and location of the surgical site, clinical resources, and the risks and benefits of each method should be carefully considered when selecting a surgical technique.

  • The Q-switched ruby laser, Q-switched alexandrite laser, and Q-switched Nd:YAG laser are effective modalities for laser-mediated depigmentation in vitiligo.

image Pitfalls and Cautions

  • Micropigmentation is generally not recommended for camouflage due to associated long-term complications.

  • All techniques involve possible risks of undesirable scarring, textural mismatch, and color mismatch.

  • These techniques should be used only with extreme caution in patients with a history of keloid formation.

image Patient Education Points

  • Preoperatively, patients must understand that it may take months to years to achieve the full extent of repigmentation and color match, and that surgery is a treatment, not a cure for the disease.

  • Although it has been shown to improve quality of life, vitiligo surgery is currently not covered by insurance in the United States, making it unavailable to many patients.

INTRODUCTION

Vitiligo is characterized by the development of depigmented macules and patches, and occurs through the mechanism of melanocyte destruction. Treatment focuses on repigmentation and disease stabilization using medical, light-based, and surgical therapies; though each of these approaches may be used independently, combination approaches are frequently utilized to optimize outcomes.

Surgical approaches are effective for select patients with vitiligo. Existing techniques in vitiligo surgery have undergone significant refinement and continue to evolve, with a focus on optimizing treatment outcomes as well as physician and patient satisfaction. Though relatively underperformed, vitiligo surgery has become increasingly popular due to the limitations of medical therapies for vitiligo.

PREOPERATIVE EVALUATION

Patient selection

Vitiligo surgery is typically considered after patients have failed conservative measures such as medical and ...
