Carbon dioxide laser excision as a novel treatment for large xanthelasma palpebrarum: long-term efficacy and safety.

AIMS: This study evaluates the long-term efficacy and safety of carbon dioxide (CO₂) laser excision as a novel treatment for large xanthelasma palpebrarum.

METHODS

The study included 295 patients diagnosed with xanthelasma palpebrarum, categorised as 246 patients with grade I, 16 with grade II, 22 patients with grade III and 11 with grade IV lesions. All underwent CO₂ laser excision and were followed up for a 12-month period. Treatment efficacy was assessed through clearance and recurrence rates, evaluated using digital photography and complications were recorded.

RESULTS

The participant group consisted of 66 males and 229 females, with an average age of 41.7±11.6 years. Clearance rates exceeded 99% for grades I-III and were around 95% for grade IV lesions. The recurrence rate was 6.8%, with higher recurrence rates observed in lesions over 2 mm in height compared with those under 2 mm (p<0.001). The main complications over the 12-month follow-up were scarring (4.4%), hyperpigmentation (8.1%) and hypopigmentation (8.5%), with no severe complications reported.

CONCLUSION

CO₂ laser excision emerges as a precise, minimally invasive and effective modality for treating xanthelasma palpebrarum, marking a significant advancement in treatment modalities. Further research is required to reinforce these results and refine treatment protocols.
