摘要

Since the introduction of CO2 fractional laser in dermatology, multiple clinical evidences have shown its effectiveness in treating alopecia areata(AA). However, the extent of efficacy remains under-researched, with a lack of extensive and large-scale comparisons, which is a topic of global discussion. We present a case of a 13-year-old male child with AA. After taking '10 mg oral prednisone acetate' three times daily, applying' compound Siyadan ointment' twice daily, and receiving CO2 fractional laser treatment with different parameters on different area once a month. After three months of treatment, the patient's lesions had fully resolved. It was observed that hair growth varied among different parameter regions.
