During the operation, local anesthesia will be used to minimize the pain of men undergoing surgery. After the operation, the doctor will make an incision in your nostril and then put the prosthesis in. Because the incision is very hidden, the man who underwent the operation can't see any traces after the operation. Under normal circumstances, the operation can be completed within 1 hour. The commonly used prosthetic materials in male surgery are solid silica gel and swelling.
