چکیده

مقدمه: لکودرمای ناشی از سوختگی، اغلب در همراهی با اختلالات روانی- اجتماعی در بیماران می‌باشد. تکنیک‌های جراحی مختلفی جهت درمان لکودرمای سوختگی وجود دارد. یکی از مهم‌ترین روش‌های جراحی در درمان این عارضه‌ی ناخوشایند، پیوند سلولی ملانوسیت-کراتینوسیت می‌باشد. این مطالعه جهت ارزیابی اثر پیوند سلولی ملانوسیت- کراتینوسیت در بیماران لکودرمای سوختگی با استفاده از دو تکنیک Dermabrasion و لیزر Erbium YAG جهت انتقال سوسپانسیون طراحی و اجرا گردید.روش‌ها: در این مطالعه، 11 بیمار با 44 ضایعه‌‌ی لکودرما به صورت تصادفی به دو گروه Dermabrasion و لیزر Erbium YAG جهت انتقال سوسپانسیون ملانوسیت- کراتینوسیت تقسیم شدند. میزان Pigmentation مجدد و تطبیق رنگ 6 ماه بعد از درمان ارزیابی گردید.یافته‌ها: میانگین درصد Pigmentation مجدد در گروهی که با تکنیک Dermabrasion درمان شده بودند، 80/25 ± 20/64 و در گروه لیزر 40/9 ± 00/20 بود (001/0 > P). به جز 1 مورد اسکار هایپرتروفیک و 1 مورد Hyperpigmentation که به ترتیب در محل دهنده و گیرنده دیده شد، عوارض جانبی قابل ملاحظه‌ای مشاهده نشد.نتیجه‌گیری: پیوند سلولی ملانوسیت- کراتینوسیت روش مؤثر و بی‌خطری در درمان اسکار لکودرمای سوختگی می‌باشد. نتایج بهتری با Dermabrasion در برداشتن اپیدرم به دست آمد. مطالعات بیشتری در اثبات تأثیر سوسپانسیون سلولی در درمان لکودرمای سوختگی نیاز می‌باشد.

چکیده [English]

Background: Postburn leukoderma often is associated with psychosocial disabilities in patients. Several surgical techniques are suggested for the treatment of leukodermic burn scars. Melanocyte-keratinocyte transplant procedure (MKTP) is an important surgical modality for the treatment of this unpleasant complication. This study was designed to assess the efficacy of melanocyte-keratinocyte transplant procedure in postburn leukoderma using dermabrasion or Erbium YAG laser for recipient site preparation.Methods: 11 patients with 44 leukoderma lesions were randomized into two groups of dermabrasion-treated or Erbium-YAG-laser- treated recipient site for melanocyte-keratinocyte transplant procedure. Repigmentation rate and color matching were assessed at least 6 months after the treatment.Findings: The mean percentage of repigmentation in was 64.20 ± 25.80 and 20.00 ± 9.40 in dermabrasion-treated and Erbium-YAG-laser treated groups, respectively (P < 0.001). In dermabrasion group, patients were significantly more satisfied than laser. No major adverse effects were observed except for hypertrophic scar and postinflammatory hyperpigmentation in 2 patients at the donor and recipient sites, respectively.Conclusion: Transplantation of autologous melanocyte-keratinocyte suspension could be considered as an effective and potentially safe treatment in leukodermic burn scars. Better results were achieved with dermabrasion for de-epithelialization of the recipient sites compared to Erbium YAG laser. Further studies on larger series of patients are needed to confirm the efficacy of melanocyte-keratinocyte transplant procedure in treating postburn leukoderma.
