Topical compound lidocaine cream is commonly used for pain relief before laser treatment for scar. In January, 2020, one 4-year-old girl with large area scar was admitted to the Department of Plastic Surgery, Taizhou Hospital of Zhejiang Province. Severe adverse drug reaction such as convulsions, cyanosis of the lips, loss of consciousness, and urination incontinence occurred, after 1.5 hours of topical application of compound lidocaine cream before laser treatment. She was recoved after emergency treatment.

Eyelid and surrounding tissue injury caused by trauma, burn, infection and other reasons will lead to different degrees of eyelid ectropion and incomplete eyelid closure after scar formation. At present, surgical treatment is the main treatment for cicatricial ectropion, but there is still the risk of scar formation again after operation. We used early ion beam drug introduction to treat 1 case of cicatricial ectropion after trauma, and achieved satisfactory result.
