Clinical Case Report: CO₂ Laser Removal of Facial Moles
Case Presentation A 35‑year‑old man presented with a pigmented lesion on the left cheek. On closer examination, the lesion was composed of two adjacent melanocytic nevi. One was darker in color with a deeper dermal root, while the other was lighter in pigmentation and more superficial. Both lesions were clinically benign, confirmed by examination and dermoscopic evaluation. The patient expressed concern about the cosmetic appearance and requested removal for aesthetic improvement.
Treatment Given the patient’s preference for a good cosmetic outcome, CO₂ laser ablation was chosen. The laser was applied with controlled energy to vaporize the lesions layer by layer. Care was taken to address the deeper root of the darker mole while minimizing collateral damage to surrounding tissue.
Post‑operative Course Immediately after the procedure, two superficial wounds were present at the sites of the removed moles.
- Healing phase: Within two weeks, the scabs detached spontaneously, revealing immature scars.
- Scar evolution: Over the following months, the scars gradually faded. By five months post‑procedure, the lighter mole site had healed completely without any visible trace. The darker mole site left a mildly depressed, skin‑colored scar, but the redness had fully resolved.
Discussion This case illustrates the effectiveness of CO₂ laser in removing compound facial nevi with minimal downtime. The differential depth of the two lesions influenced the healing outcome: the superficial mole healed without residual scarring, while the deeper mole left a subtle depressed scar. Nonetheless, the overall cosmetic result was satisfactory, and the patient reported high satisfaction.
Conclusion CO₂ laser ablation provides a safe and cosmetically favorable option for benign facial moles, especially when patients seek minimal scarring and rapid recovery. Depth of lesion remains a key factor in predicting scar outcome, highlighting the importance of individualized treatment planning.
臨床病例報告：二氧化碳激光去除面部痣
病例介紹 患者為 35 歲男性，左臉頰有一處色素性病灶。詳細檢查後發現該病灶由兩個相鄰的痣組成，其中一個顏色較深，根部較深；另一個顏色較淺，根部較淺。兩者經臨床及皮膚鏡檢查均為良性。由於患者對外觀有顧慮並希望獲得良好的美容效果，因此選擇進行二氧化碳激光去除。
治療過程 在局部麻醉下，使用 CO₂ 激光逐層汽化病灶組織。針對較深的痣，激光能量控制更為精準，以確保徹底去除並減少周圍組織損傷。
術後經過 治療後，左臉頰原痣位置留下兩個淺表創口。
- 癒合期：兩週後痂皮自然脫落，顯露出早期瘢痕。
- 瘢痕演變：隨後數月內瘢痕逐漸淡化。術後五個月時，淺色痣部位已完全癒合，無任何痕跡；深色痣部位則留下輕度凹陷、接近膚色的瘢痕，紅色消退完全。
討論 此病例顯示 CO₂ 激光在去除面部複合痣方面的有效性與安全性。痣的深度對術後瘢痕結果有顯著影響：淺表痣癒合後無殘留痕跡，而深部痣則可能留下輕微凹陷性瘢痕。整體美容效果良好，患者對結果表示滿意。
結論 二氧化碳激光是一種安全、有效且美容效果佳的良性面部痣去除方法。病灶深度是影響術後瘢痕的重要因素，因此治療計劃需根據病灶特徵個別制定，以達到最佳美容效果。
