SuperpulsedCO2Laser with Intraoperative Pathologic Assessment for Treatment of Periorbital Basal Cell Carcinoma Involving Eyelash Line

摘要

Background. Periorbital basal cell carcinoma (BCC) is considered a high risk case because it is associated with high rate of recurrence and complication. Superpulsed CO2laser with intraoperative pathologic assessment could be an alternative and appropriate treatment for periocular lesions where Mohs micrographic surgery is not available.Objective. To evaluate the efficacy of superpulsed CO2laser therapy with intraoperative pathologic assessment on periocular BCC involving eyelash line.Method. This follow-up study was performed on 20 patients with a total of 21 BCC lesions that were pathologically documented. Firstly, debulkation of tumoral mass was done by curettage. Then, irradiation and intraoperative pathologic evaluation were done by concurrent CO2laser. The patients were followed up for a period of 36 months.Results. Out of 21 lesions, the nodular type accounted for 15 (71.4%) lesions, and 12 (57.1%) lesions were seen in the lower lid as the most common clinical type and site involvement. Twenty BCC lesions (95.2%) were treated after one session. Damage to eyelash was seen in 2 (10%) patients, but ectropion and other complications were not seen in any patient.Conclusion. Treatment with superpulsed CO2laser and intraoperative pathologic evaluation for periorbital BCC lesions much close to conjunctiva could be an effective method with minimal complications without major danger of recurrence. This modality can be used with care in the inner canthus and high risk pathologic lesions.
