Where does Changsha have a hospital to remove OTA's nevus? How much does it cost to go to OTA mole? My sister's baby has just been born and has a blue mole on her face. The doctor said it was OTA's mole. At present, laser surgery is generally used to remove nevus of OTA, and the cost is about 8000 to 10000. It is recommended to choose a regular big hospital, such as facial plastic surgery by Dr. Changsha, to ensure the safety of children, and it is best to do it when children are still young.
