Purpose: The prevalence of skin cancers and cutaneous premalignant lesions are increasing recently. It is necessary to treat cutaneous premalignant lesions, because these can progress to invasive skin cancers. We conducted a retrospective study to evaluate the usefulness of $CO_2$ laser resurfacing in skin tumor surgery. Methods: From 2005 to 2008, 14 patients with skin cancers, photodamaged skin and cutaneous premalignant lesions were treated with skin cancer excision, immediate reconstruction, and $CO_2$ facial laser resurfacing. Mean average follow-up period was 15.6 months (5 months - 36 months). Biopsy and clinical photograph were taken preoperatively, intraoperatively and through follow-up period to assess the effectiveness of laser resurfacing. Recurrence and side effects were evaluated through follow-up period. Results: Histologic examination shows the abolition of actinic atypia, regeneration of epidermis and normalization of cellular differentiation after laser resurfacing. Clinical photographs shows elimination of keratoses and spots, and the homogeneous, smoothening change of skin surface, indicating healthy and younger faces. All patients had remained free of skin cancers and premalignant lesions in laser-treated field through follow-up period. Conclusion: $CO_2$ laser resurfacing in skin tumor surgery can treat not only premalignant lesions but also subclinical lesions of photodamaged skin. Moreover it may be helpful in prophylaxis against skin cancers and premalignant lesions, providing rejuvenation and cosmetic improvement.
