Abstract(s)
Desde sempre a mulher tentou alcançar o corpo perfeito, recorrendo a variados tratamentos e tecnologias para atingir tal fim. Um dos problemas que mais despoletou esta procura é a Lipodistrofia Ginoide (LG), popularmente conhecida por celulite. Um dos tratamentos que tem por vista colmatar este problema é a lipoaspiração, que remonta à década de 80, mas actualmente a lipoaspiração não invasiva por ultra-sons (LNIUS) caracteriza-se por ser o tratamento que melhores resultados alcança, em termos de tempo e custo. Por esta razão, inúmeros são os centros de estética que disponibilizam este tratamento. Contudo, a totalidade dos riscos intrínsecos a esta tecnologia continuam desconhecidos. O desconhecimento dos padrões de propagação da onda ultrasónica e da forma de aquecimento do tecido biológico aumentam os riscos de efeitos secundários. A carência de métodos acessíveis e de fácil manipulação para avaliar o desempenho dos equipamentos de LNIUS conduz a uma débil informação a respeito da periodicidade com que estes aparelhos devem ser calibrados. Assim, um dos principais problemas destes equipamentos é a falta de calibração e difícil verificação da potência emitida. Este estudo pretende explorar o problema da LG e quais as vantagens e desvantagens na tecnologia existente no tratamento da mesma. Um equipamento de LNIUS, o Magic Station, é o principal alvo de análise, avaliando as suas características de funcionamento, e definindo um método que permita avaliar a potência emitida pelo transdutor de ultra-sons (US). Pretende-se também analisar o panorama actual da aplicação da LNIUS em Portugal através de questionários efectuados em diversos centros de estética. Os resultados permitem aferir o conhecimento dos colaboradores destes centros, com formação técnica ou não, sobre as particularidades que envolvem a utilização deste tipo de dispositivos.
From the begining, women have always tried to achieve the perfect body, using a range of treatments and technologies to reach such results. One of the problems that triggers this demand is the gynoid lipodystrophy (LG), commonly known as cellulite. One of the treatments that tries to solve this problem is Liposuction, and it dates back to the 80s but nowdays non-invasive ultrasonic liposuction seams to be the treatment that achieves better results, considering the relation time versus costs. For this reason, there are a numerous of beauty salons that offer this treatment. However, the risks inherent to this treatment are still unknown. The lack of standards of ultrasonic wave propagation and the form of heating of biological tissue increases the risk of side effects. The absence of accessible and easily manipulated methods to evaluate the performance of noninvasive ultrasonic liposuction leads to a weak information about the frequency with which these devices must be calibrated. Therefor, the major problem in these devices is the nonexistence of calibration and verification of emitted power. This study explores the problem of LG and the advantages and disadvantages of the technologies associated. A particular ultrasonic liposuction device, the Magic station, is the main target of this analysis. Its working characteristics are analysed, in order to find a methodology for assessing the power emitted by the ultrasonic transducer. It’s also intended an analysis in howthe ultrasonic liposuction treatments are made in Portugal. For this, it was made a questionnaire carried out at various beauty salons. The questionnaire results allowed assessing the knowledge of workers of beauty centers, with technical training or not, on specific issues involving the use of such devices.
