Patient: Can split moles be operated on? Is it risky? What is the approximate cost of surgery? Doctor: Surgery is possible, and the sooner the better. Because the split nevus will gradually increase in size with age, the surgery will be more traumatic and difficult. If the extent of the split nevus does not involve the lid margin and lid plate as well as the tear duct, the surgery is relatively easier, and vice versa, it is more complicated. The cost of surgery for a child is approximately$8,000-10,000.
