Hello, when a man comes to see a doctor, he must be prepared in all aspects. It is best to explain his expectations and requirements in detail and have a full discussion with the doctor. You may just be dissatisfied with the shape of a certain part of yourself and don't know how to make it more perfect. At this time, you should carefully consider the doctor's advice until you are sure that the expected goal of the operation meets your own situation and requirements. In addition, you can consult other doctors. If you have any questions about the operation or the effect of the operation, you should have a serious and thorough discussion with the doctor. You should carefully weigh the risk you will take and the price you will pay. Any operation will cause trauma to the body, so it will be accompanied by adverse outcomes, such as traumatic reaction, incision scar, pigmentation and so on. Although the incidence of postoperative bleeding, hematoma, seroma, infection and delayed healing is not high, it cannot be completely avoided. Surgery may also change the original morphological or facial features, such as the changes of hairline and sideburns when forehead rhytidectomy is performed through hairline incision. Many factors will directly or indirectly affect the surgical results, so predicting the surgical results is the same as predicting the weather, and strict and responsible doctors will not make specific and exact commitments. Even if the operation is performed by the most experienced doctor, it may not meet the expectations, and complications may occur or some minor cosmetic surgery may be needed. The expenses of these disposal and repair operations also need to be borne by yourself. Get enough rest and sleep a few days before the operation. Two weeks before operation, you should quit smoking and drinking, stop using drugs containing aspirin and vitamin E, drink less tea and coffee, and limit the processing of dairy products or other foods. Taking vitamin K 5mg every day for 3-5 days before operation can reduce skin cyanosis caused by surgical bleeding. If the expectation is practical, rather than the pursuit of absolute perfection, and the doctor can fully understand your requirements and have enough knowledge, experience and responsibility, then in most cases, men will be satisfied or even surprised with the result of the operation.
