Background and Objective. Some Plastic Surgery operations have a long wait in public hospitals in Chile as they are less priority in a system with the typical economic deficiencies of a developing country. With a public service objective, members of the Chilean Society of Plastic Surgery have been developing an altruistic health operation in the last 2 years, in collaboration with the Ministry of Health. We present the latest campaign of breast reduction surgery performed in 2019. Methods. Retrospective review of the health operative for breast reduction surgery at the Valdivia Hospital (Chile). We present the patient selection protocol, the surgical techniques used and the evaluation of results. Results. Throughout 2 days, 15 patients were operated on by a group of 8 specialists divided into 2 work groups. All the complications were mediate and minor. Conclusions. Although these surgical operatives are not the solution for the waiting lists of Plastic Surgery in public hospitals in Chile, they help to improve them and prove to be effective with adequate scientific and administrative planning.
