Case Report: CO₂ Laser Removal of a Facial Mole
Patient History
A 45‑year‑old woman presented with a long‑standing pigmented skin mole located on the left side of her face, approximately 2 cm anterior to the left ear. The lesion had been present for over 15 years and was clinically benign.
Procedure
CO₂ laser surgery was performed to completely ablate the mole, including its deep root, to minimize the risk of recurrence. Due to the depth of the lesion, the wound extended into the deeper dermal layers. To ensure optimal healing, the wound was sutured immediately after laser ablation. Suturing provided several benefits:
- Faster recovery time
- Reduced risk of secondary infection
- Prevention of excessive scar formation
Outcome
At the six‑month follow‑up, the surgical scar was almost invisible. The patient reported satisfaction with both the cosmetic and functional outcome.
Discussion
CO₂ laser therapy is a well‑established technique for the removal of benign skin lesions such as moles. Its advantages include:
- Precise tissue vaporization with minimal collateral damage
- Effective eradication of the lesion root, reducing recurrence risk
- Superior cosmetic results compared to traditional excision
In cases where the mole extends deeply, adjunctive suturing is recommended to promote rapid healing and minimize scarring. This case highlights the importance of combining advanced laser technology with conventional surgical principles to achieve both medical safety and aesthetic excellence.
Conclusion
CO₂ laser removal of benign facial moles is a safe and effective procedure. When combined with appropriate wound closure techniques, it can yield excellent cosmetic outcomes, with scars that are barely perceptible within months of treatment.
病例報告：CO₂ 雷射去除臉部痣
病史
患者為 45 歲女性，左臉靠近耳前約 2 公分處有一顆黑色皮膚痣，存在已逾 15 年。臨床判斷為良性病灶。
手術過程
採用 CO₂ 雷射手術，將整顆痣連同其深層根部完全汽化，以避免復發。由於病灶根部較深，術後傷口亦較深，因此進行縫合。縫合的目的包括：
- 加速傷口癒合
- 降低感染風險
- 減少疤痕深度
術後結果
六個月後回診，傷口疤痕幾乎不可見。患者對美容效果及功能性結果均十分滿意。
討論
CO₂ 雷射是去除良性皮膚病灶（如痣）的成熟技術，具備以下優點：
- 精準汽化病灶組織，減少周邊損傷
- 能徹底清除病灶根部，降低復發率
- 相較傳統切除手術，美容效果更佳
若病灶深入皮膚，術後縫合可促進癒合並減少疤痕。本案例顯示，將先進雷射技術與傳統外科縫合結合，可同時兼顧醫療安全與美容效果。
結論
CO₂ 雷射去除良性臉部痣是一種安全且有效的治療方式。若配合適當的傷口縫合技術，術後可獲得極佳的美容結果，疤痕在數月內幾乎不可見。
