Hi Jill, thanks for your question. The decision to have plastic surgery is extremely personal. Besides making your twin sister happy, you will have to decide if the benefits will achieve your own goals and if the risks and potential complications of rhinoplasty are acceptable. These risks or complications include: bleeding (hematoma), infection, anaesthesia risks, poor wound healing/ scarring, numbness or pain, nasal septal perforation, difficulty breathing, skin discoloration and swelling, unsatisfactory nasal appearance. While initial swelling subsides within a few weeks, it may take up to a year for your new nasal contour to fully refine. During this time you may notice gradual changes in the appearance of your nose as it refines to a more permanent outcome. As your body ages, it is natural to have some gradual changes to your face including your nose. But most of your improvement should be relatively permanent. A healthy lifestyle and life-long sun protection will help extend the results of your new appearance. These risks and others will be fully discussed prior to your consent. It is important that you address all your questions directly with your plastic surgeon.
