BACKGROUND: With the increase of the population obesity indices occurred a growth of the numbers of ex-obese patients and aesthetic/reconstructive plastic surgery in this population. Objectives: To present a systematic approach adopted in patients undergoing breast surgery after massive weight loss at Hospital Geral de Goiânia (HGG) in the last 10 years, and assess the results.
METHOD: We conducted a retrospective study of cases of breast surgery after massive weight loss in the Department of Plastic Surgery of HGG, from January 2002 to December 2011. The patients were individually analyzed preoperatively and submitted to the classification of Kaluf to breast dysmorphism after major weight loss. The operative technique varied depending on the classification of the type of breast.
RESULTS: The sample totaled 73 female patients, with mean age of 44 years and mean weight loss of 48 kg. In 41 patients (56.16%) was used the technique with inclusion of prostheses and in 32 (43.83 %) chose to not include silicone implants. Complications occurred in eight patients (10.95%), one case of hematoma (1.36%), two cases of suffering partial nipple-areola complex (2.73%), five cases of small suture dehiscence or delayed healing (6.84%) and one case of breast ptosis in the immediate postoperative period (1.36%).
CONCLUSION: Due to the wide range of dimorphisms in emaciated patients, in particular changes in their breasts, we note that it is necessary to establish protocols and routines for effective assessment and treatment, with the least possible morbidity, associated with better cosmetic results.

INTRODUÇÃO: Com o aumento dos índices de obesidade populacional ocorreu um crescimento do número de pacientes ex-obesos, e de cirurgias plásticas nesta população.
OBJETIVOS: Apresentar a sistematização e conduta adotada nos pacientes submetidos a mamoplastia, após grande perda ponderal, operados no Hospital Geral de Goiânia (HGG) nos últimos 10 anos, bem como avaliar os resultados obtidos.
Método: Foi realizado um estudo retrospectivo dos casos de mamoplastia após grande perda ponderal, operados no Serviço de Cirurgia Plástica do HGG, de janeiro de 2002 a dezembro de 2011. As pacientes foram analisadas individualmente no pré-operatório e submetidas à classificação de Kaluf, para dismorfias mamárias após grande emagrecimento. A técnica operatória variou em função da classificação do tipo de mama.
RESULTADOS: A casuística totalizou 73 pacientes, do sexo feminino, com faixa etária média de 44 anos, e perda ponderal média de 48 Kg. Em 41 pacientes (56,16%) foi utilizada a técnica com inclusão de próteses, e em 32 (43,83%) optou-se por não incluir os implantes de silicone. As complicações ocorreram em oito pacientes (10,95%), sendo um caso de hematoma (1,36%), dois casos de sofrimento parcial do complexo aréolo-mamilar (2,73%), cinco casos de pequenas deiscências de sutura ou retardo de cicatrização (6,84%) e um caso de ptose de mama no pós-operatório imediato (1,36%).
CONCLUSÃO: Devido à grande variação de dismorfismos em pacientes emagrecidos, em especial as alterações mamárias, notamos que se torna necessário o estabelecimento de protocolos e rotinas para avaliações e tratamentos eficazes, com a menor morbimortalidade possível, associados aos melhores resultados estéticos.

The incidence of obesity has currently increased dramatically, with 40% of Brazilian women and 30% of Brazilian men considered obese. The number of ex-obese patients has also increased owing to gastroplasty or nutritional diets.

Plastic surgeons have started working on this area of aesthetic and corrective surgery, wherein patients present specific features concerning their skin and subcutaneous tissues in addition to systemic alterations and comorbidities, which require integration with other specialties and professionals to ensure adequate patient support.

Several body deformities are observed when a patient undergoes massive weight loss, including breast dysmorphisms, which are frequently caused by atrophy and/or breast ptosis. In such cases, the patients may present with flaccid and less elastic skin due to edema and rupture of the collagen fibers in the dermis (Figures 1 and 2).

To describe the systematization and management of patients who experienced massive weight loss after they underwent mammoplasty at the Hospital Geral de Goiânia (HGG) within the last 10 years and to analyze the results.


After approval by the ethics committee, we conducted a retrospective study of patients who experienced massive weight loss after they underwent mammoplasty at the Plastic Surgery Service of the HGG between January 2002 and December 2011.

The study included patients with morbid obesity who had experienced massive weight loss (>40%) after mammoplasty, with or without the use of prosthetic devices.

The patients were evaluated individually during the preoperative assessment and classified into three groups according to the amount of breast tissue, ptosis, and breast asymmetry (Figures 3-5).

The selected surgical technique varied according to breast type, as shown in Table 1 and Figures 6-11.

A total of 73 female patients (mean age, 44 years; range, 21-68 years) and weight loss of 48 kg (31-75 kg) were included in this study.

Prosthetic devices were used in 41 patients (56.16%), whereas a choice was made not to use silicone-based implants in 32 patients (43.83%), as illustrated in Figures 20-37.

Complications occurred in eight patients (10.95%), including one case of hematoma (1.36%), two cases of partial damage (between 15% and 25%) to the nipple-areola complex (2.73%), five cases of small dehiscences along the sutured lines or delayed healing (6.84%), and one case of breast ptosis during the immediate postoperative period (1.36%).


Patients who experienced massive weight loss should be followed up by an interdisciplinary team, as they require specific evaluations and treatments owing to peculiarities and alterations in various organ systems, which must be identified and controlled in order to provide the best results and to reduce incidence of complications.

Considering the complexity and great number of clinical alterations that occur in ex-obese patients, we adopted specific protocols to manage such patients who attend the Plastic Surgery Service of the HGG, including the timing of surgery and the minimal inclusion criteria, which are associated with preoperative tests and evaluations, that patients should meet to qualify for surgery.

Standard mammoplasty procedures were adopted for ex-obese patients, which varied according to the patients' breast types. Because the surgical strategy and technique are predefined during outpatient consultation, the procedure can be performed with greater safety in a shorter duration, and with better postoperative outcomes.


The increase in the number of ex-obese patients has led to a parallel increase in the number of aesthetic/corrective procedures performed by plastic surgeons in this patient group. Therefore, plastic surgeons should have better knowledge of the peculiarities and alterations that occur in a person's body after massive weight loss.

Considering the broad range of dysmorphisms observed in our patients after massive weight loss, especially in relation to the breast area, we conclude that establishment of routine evaluation protocols and the use of effective therapies to minimize morbimortality as much as possible while providing the best aesthetic results are necessary.
