This study explores the legal implications of patient consent on the liability of plastic surgeons under United Arab Emirates (UAE) legislation. In the context of aesthetic procedures, informed consent plays a crucial role in defining the responsibilities and legal exposure of medical professionals. UAE laws, particularly Federal Law No. 4 of 2016 on Medical Liability, emphasize the necessity for explicit, written, and informed patient consent prior to any medical or cosmetic intervention. The research highlights how failure to obtain proper consent can result in civil or criminal liability for plastic surgeons, even if no negligence is proven. The paper examines court rulings and legal provisions demonstrating that a valid consent form must include details of the procedure, risks, alternatives, and expected outcomes. Moreover, cultural and ethical considerations in the UAE’s legal system further shape the scope of liability and patient rights. Ultimately, the research concludes that informed consent not only protects patients' rights but also serves as a vital legal safeguard for plastic surgeons, reducing the risk of litigation when procedures have been performed competently.
