Case Series of Laser Therapy of Eyelid Peripunctal Benign Tumor.

This study is the first time to explore the feasibility of CO laser treating some eyelid lacrimal puncta benign tumor. Eyelid lacrimal papillae is special anatomy region. Treatment of eyelid peripunctal tumor is relatively intractable and needs reconstruction of the lacrimal passage in most of the time. We use super pulse CO laser to treat peripunctal benign tumor and appears to be effective. It contained 12 participants treated with super pulse CO laser photocoagulation without lacrimal duct silicone tube placement. The areas of lesions were as follows: eight cases were located in the upper eyelid lacrimal puncta, four cases in the lower lacrimal puncta. Super pulse CO laser was used to treat it. The follow-up period was 4 weeks, 24 weeks, and 3 years after treatment. Histological diagnoses were obtained in all patients. All patients were satisfactory after treatment with their cosmetic outcomes, and the wounds are dry, with no infections. No patient has functional damage, secondary epiphora, and lacrimal drainage system obstruction. Complete epithelialization occurs 2-4 weeks after treatment and forms normal epithelium. It showed no obvious scars or notches after treatment, and only temporarily less hyperpigmentation is in the treated area than the circumambient normal skin. During the follow-up period, there were no complications and no relapses were observed. Super pulse CO laser therapy for eyelid peripunctal benign tumors without lacrimal duct silicone tube placement sometime appears to be available, effective, and well-tolerated alternative to traditional surgery in the clinic, especially for selected disease. The IRB proved number is 2016034.
