ABSTRACT
RESUMO Introdução: A mamoplastia redutora feminina visa restaurar o volume fisiológico das mamas em casos de hipertrofia mamária, de modo a manter a simetria e com um número mínimo de complicações. Embora tal procedimento seja usual, a literatura carece de dados epidemiológicos e descritivos acerca da cirurgia de redução de mama. Desse modo, esse estudo tem como objetivo descrever a prevalência da mamoplastia redutora no Brasil dos anos de 2015 a 2019; comparar a prevalência de mamoplastia redutora entre as regiões do Brasil de 2015-2018 com a do ano de 2019; e avaliar a relação entre a renda familiar regional e a prevalência da mamoplastia redutora feminina no país de 2015-2019. Métodos: Estudo ecológico de base populacional cujos dados foram coletados por meio do Departamento de Informática do Sistema Único de Saúde e censos demográficos do Instituto Brasileiro de Geografia e Estatística. Foram coletados dados de 2015 a 2019. Resultados: A prevalência de mamoplastia redutora no Brasil no ano de 2019 foi de 0.08%, enquanto que nos anos de 2015 a 2018, essa prevalência foi de 0.07%. Não houve diferença estatisticamente significante quando comparadas as prevalências regionais dos anos de 2015 a 2018 com a prevalência de 2019. As prevalências de mamoplastia redutora nas regiões do Brasil de 2015-2019 apresentaram correlação positiva moderada com renda domiciliar média per capita. Conclusão: A prevalência de mamoplastia redutora feminina no Brasil apresenta uma tendência de estabilidade temporal ao longo dos anos de 2015-2019 e-m âmbito nacional e regional. Sugere-se uma correlação positiva entre a renda familiar per capita regional e a prevalência desse procedimento.
ABSTRACT Introduction: Female reducing mammoplasty aims to restore the physiological volume of the breasts in cases of breast hypertrophy, to maintain symmetry and with a minimum number of complications. Although such a procedure is usual, the literature lacks epidemiological and descriptive data on breast reduction surgery. Thus, this study aims to describe the prevalence of reducing mammoplasty in Brazil from 2015 to 2019; to compare the prevalence of reducing mammoplasty among the regions of Brazil from 2015-2018 with that of 2019, and to evaluate the relationship between regional family income and the prevalence of female reduction mammoplasty in the country of 2015-2019. Methods: Population-based ecological study whose data were collected through Informatics Department of the Unified Health System and Brazilian Institute of Geography and Statistics demographic censuses. Data were collected from 2015 to 2019. Results: The prevalence of reducing mammoplasty in Brazil in 2019 was 0.08%, while from 2015 to 2018, this prevalence was 0.07%. There was no statistically significant difference compared to the regional prevalence from 2015 to 2018 with the prevalence of 2019. The prevalence of reducing mammoplasty in the regions of Brazil from 2015-2019 showed a moderate positive correlation with average household income per capita. Conclusion: The prevalence of female reduction mammoplasty in Brazil shows a trend of temporal stability over the years 2015-2019 at national and regional levels. A positive correlation between regional per capita family income and the prevalence of this procedure is suggested.
ABSTRACT
BACKGROUND: The first visible change in an aging face and neck is the loss of neck contour, which can be corrected by treating the platysmal bands; however, it remains unclear as to which is the best strategy to approach these bands. The aim of the present study is to verify whether the lateral platysmal bands approaches, before the medial ones, cause widening of the gap between them. METHODS: This is a prospective, randomized, comparative study involving 30 individuals presenting various stages of neck and facial flaccidity and sagging. The patients were split into 2 groups according to the lateral platysmal approach (group A: lateral platysmal traction/plication; group B: lateral platysmal undermined/traction). A protocol was established to measure the gap between the medial bands, 3 and 5 cm away from the chin, before and after superficial musculoaponeurotic system/platysma lateral suspension. Measurements were taken using a compass and a ruler. The endpoint was to determine whether the gap between the medial platysmal bands widens after the lateral procedure. RESULTS: Group A, first measure (1-M): the gap ranged between 1.0 and 1.6 cm in point M3 (3 cm away from chin) and between 1.8 and 3.0 cm in point M5 (5 cm away from chin) (mean in M3 = 1.2; SD, 0.22 and mean in M5 =2.3; SD, 0.52). Group A, second measure (2-M): the measure ranged between 1.0 and 1.7 cm in point M3 and between 1.8 and 3.2 cm in point M5 (mean = 1.28; SD, 0.25 and mean = 2.42; SD, 0.63, respectively). Group B, first measure (1-M): the gap ranged between 1.1 and 1.7 cm in M3 (mean = 1.32; SD, 0.21) and between 1.8 and 3.2 cm in M5 (mean = 2.38; SD, 0.57). Group B, second measure (2-M): the measure ranged between 1.2 and 1.7 cm in M3 (mean = 1.4; SD, 0.18) and between 2.0 and 3.2 cm in M5 (mean = 2.5; SD, 0.55). Group A: P = 0.07 (M3) and 0.10 (M5); Group B: P = 0.09 (M3) and 0.07 (M5). CONCLUSION: The lateral platysmal approach, plication or undermined, does not lead to a widening of the gap between the medial platysmal bands.
ABSTRACT
BACKGROUND: Studies have demonstrated the importance of anthropometric measurements of the breasts, based on linear measurements for the selection of the volume of breast implants, their positioning, and surgical planning. OBJECTIVES: The objective of this study is to evaluate the main changes in anthropometric measurements in breast augmentation. METHODS: A prospective, randomized clinical study with 74 female candidates for breast augmentation. All the individuals were split into five groups, according to the implant volume. The implants used were of different textures, from three different brands (LifeSil, Politech, and Silimed). The following measures were taken: distance from the nipple to the inframammary fold (N-IMF), inter-nipple-areolar complex distance (N-N), distance from the Sternal notch to the Nipple (SN-N), areola diameter, and breast projection. RESULTS: The most significant breast anthropometric alteration after mammoplasty was the N-IMF distance; that is, an expansion of the lower pole of the breast, followed by an increase in the areolar diameter. Mostly of measurements showed stability between 3rd and 6th months after the surgery. The projection was the most interesting measure due to presenting two patterns of behavior according to the analysis criteria performed. When comparing the implant projection and the final breast projection, it was observed that the implant profile represented a 27% increase in the final breast projection. CONCLUSIONS: This study provides an essential comparative analysis between anthropometric changes in breast augmentations and serves as a predictive tool in the preoperative evaluation of the patient during surgical planning.
