Answer

Avulsion therapy by chemical or surgical means can be used as an alternative therapy for psoriatic nail disease. Chemical avulsion therapy includes the use of urea ointment in a special compound to the affected nail under occlusion for 7 days, and the nail is removed atraumatically. Chemical avulsion therapy is painless, involves no blood loss, and is less expensive than surgical avulsion.

Surgical avulsion therapy can be performed for psoriatic nail disease when other treatments have failed. During surgery, the matrix can be electively ablated to prevent regrowth of the nail. This procedure is performed under local anesthesia. Inform patients of postoperative discomfort, limitations, and possible physical nail disfigurement.
