Avaliação volumétrica e funcional do músculo glúteo máximo submetido a gluteoplastia de aumento com implantes de silicone / Volumetric and functional evaluation of the gluteus maximus muscle after augmentation gluteoplasty using silicone implants

A operação para aumento de glúteos com implantes teve início no fim da década de 1960, entretanto a técnica intramuscular, considerada padrão atualmente, foi descrita cerca de 30 anos depois. Cirurgiões e pacientes apresentam crescente interesse na realização do aumento de glúteos haja vista que sua frequência apresenta aumento nos últimos anos. A utilização de implantes intramusculares que superam o volume do músculo em mais de cinquenta por cento configura uma situação nova que deve ser estudada. O tecido muscular estriado esquelético apresenta grande suscetibilidade para atrofia secundariamente à compressão, e sendo o glúteo máximo um músculo importante na manutenção da postura ereta, deambulação, corrida e salto, é necessário pesquisar possíveis alterações musculares decorrentes da operação. O objetivo deste estudo é avaliar o volume e força do músculo glúteo máximo ao longo de 12 meses após a introdução de implantes intramusculares, o posicionamento destes implantes no interior da musculatura e mudanças antropométricas obtidas com a operação. Foram selecionadas 48 mulheres, 24 candidatas a gluteoplastia de aumento com implantes compuseram o grupo de estudo e 24 candidatas a mamoplastia de aumento compuseram o grupo controle de acordo com os critérios de inclusão e exclusão. As pacientes foram avaliadas em quatro momentos diferentes: pré-operatório e após três, seis e 12 meses da operação. Em todas as etapas foi realizada avaliação clínica nutricional, tomografia computadorizada com reconstrução 3D e teste isocinético. Todas as pacientes permaneceram afastadas de atividades físicas durante três meses após a operação. Foram utilizados implantes glúteos em gel coesivo de base oval e superfície lisa com volumes de 350 cm3 e 400 cm3. O nível de significância estatística foi mantido em 5%. As pacientes candidatas a gluteoplastia apresentaram valores da relação entre as medidas da cintura e do quadril maiores que aquelas do grupo controle...

The gluteal augmentation surgery using implants began in the late 1960s, however intramuscular technique, which is considered standard today, was described about 30 years later. Plastic surgeons and patients have increased interest in gluteal augmentation given the fact that the operation has been more frequently in recent years. The use of intramuscular implants that overcomes the muscle volume in more than fifty percent configures a new situation that should be studied. The skeletal muscle tissue shows high susceptibility to atrophy secondary to compression, and the gluteus maximus is an important muscle in the maintenance of erect posture, walking, running and jumping, it is necessary to investigate possible muscle changes resulting from the operation. The objective of this study is to assess the volume and strength of the gluteus maximus muscle during 12 months after the introduction of the implants, the position of these implants within the muscles and anthropometric changes obtained with the operation. 48 women were selected, 24 candidates for gluteal augmentation composed the study group and 24 candidates for breast augmentation composed the control group according to the criteria of inclusion and exclusion. The patients were evaluated at four different moments: pre-operatively and after three, six and 12 months of the operation. At all stages of the study, was carried out nutritional evaluation, CT with 3D reconstruction and isokinetic testing. All patients remained away from physical activities for three months after the operation. Cohesive gel, oval base and smooth surface gluteal implants were used with volumes of 350 cm3 and 400 cm3. The level of statistical significance was 5%. The patients who were candidates for gluteoplasty presented bigger waist to hip ratio than those of the control group...

Perfil das pacientes submetidas a gluteoplastia / Profile of patients undergoing gluteoplasty

Durante nossas frequentes apresentações em cursos, congressos e jornadas e mesmo em nossas publicações, existiam constantes perguntas sobre o perfil dessas pacientes. O crescente interesse da mídia e das pacientes a este respeito e também a crescente procura pela cirurgia nos estimulou a realizar este trabalho. Segundo dados da Sociedade Brasileira de Cirurgia Plástica (SBPC) e da American Society of Plastic Surgery (ASPS), referem que 20.000 pacientes foram submetidas a esta cirurgia. Em 2012, 40.000 pares de implantes glúteos foram produzidos. Existe um crescimento da cirurgia de 20% nos últimos três anos e no Brasil houve aumento de 42% em 2011. Esta tese tem como objetivo estabelecer o perfil epidermiologico das pacientes que se submetem a gluteoplastia de aumento utilizando implantes de silicone, avaliar o grau de satisfação com resultado e a correlação deste com o volume dos implantes utilizados. Cinquenta pacientes responderam a um questionário e foram examinadas pelo cirurgião e outro médico. Outras 37 pacientes foram avaliadas prospectivamente com tomografia computadorizada e volumetria, avaliação de resultado por oito cirurgiões plásticos, medidas antropométricas e correlação destas variáveis. A análise destes dados evidenciou tratar-se de cirurgia com baixo índice de complicação e alto índice de satisfação com resultado (96%). A maior procura foi por pacientes brancas (62%) e pardas (34%). Não percebemos relação de profissão ou nível socioeconômico com a procura pela cirurgia. Observou-se um alto número de pacientes que referiram naturalidade do resultado, sendo que em 94% dos casos, ninguém notou que a paciente havia se submetido à cirurgia, sem que a própria desse esta informação. As queixas, quando existiram, 4% foram referentes a terem achado as próteses pequenas. O tempo de recuperação da maioria (60%) para atividades normais foi de até 45 dias. Houve grande influência positiva na vida sexual e afetiva das pacientes que se submeteram...

This thesis aims to define the profile of patients undergoing gluteoplasty augmentation using silicone implants, as well as satisfaction with outcome. During our frequent presentations in courses, conferences and seminars and ever in our publications, there were constant questions about the profile of these patients. The growing interest of the media and the patients in this regard and also the increasing deman for surgery has encouraged us to undertake this work. According to the Brazilian Society of Plastic Surgery (SBCP) and ASPS American Society of Plastic Surgery (ASPS), reported that 200.000 patients underwent this surgery. In 2012, 40.000 pairs of buttocks implants were produced. There is a growth 20% of the surgery in the last three years and in Brazil incresead by 42% in 2011. Fifty patients completed a questionnaire and were examined by the surgeon and another doctor. Another 37 patients were prospectively evaluated with computed tomography and 3D gluteal reconstruction. The aesthetic result was evaluated by eight plastic surgeons and correlated with anthropometric measurements and volume of implants. Analysis of these data showed that it was surgery with low complication rate and high rate of satisfaction with outcome (96%). The greatest demand was for white patients (62%) and mixed (34%). We do not perceive ratio profession or socioeconomic status with the demand for surgery. We observed a high number of patients who reported naturalness of the result, and in 94% of cases, no one noticed that the patient had undergone surgery, without itself of this information. The complaints when existed 4% were found relating to prostheses small size. The recovery time of the majority (60%) to normal activities was 45 days. There was a great positive influence on sexual and affective life of patients who have undergone this surgerye...

Buttock Augmentation with Elastomer Implants

PURPOSE: The buttocks region has been associated with allure and sex appeal for centuries. Gluteal implants enable buttocks remodeling in a way that is not possible in other methods. One of the reasons that render gluteal implant surgeries unpopular is the fear of complications, the main problems being seroma, wound dehiscence, extrusion, and a visible or palpable implant. The authors present the XYZ technique, which provides anatomical reference points to guide the intramuscular dissection procedure in a feasible and safe way, resulting in a lower complication rate. METHODS: The XYZ procedure was done for buttock augmentation on 8 patients from December 2009 to June 2010. Patient's ages ranged from 27 to 44 with a mean age of 36. Seven patients were applied the 250cc sized Elastomer implants with one patient 290cc sized implant. Preoperative marking was done with the patients in the standing position. Bisection of the gluteus maximus muscle was done at the midpoint thickness to create a plane for implant insertion, which is called the sandwich plane. RESULTS: The 8 cases were performed safely without major complications. However one patient had minor wound dehiscence, and was managed with conservative treatment. Another patient had a discomfort on the buttocks for a long time. The patients were followed up for average 6 months. All patients were satisfied with the aesthetic results. CONCLUSION: In performing the XYZ technique for gluteal augmentation, the surgeon must split the muscle into two equal halves with anatomical reference points to guide the muscle detachment in a symmetrical way at an adequate depth. This method provides a guideline for the surgeon in determining the ideal plane during intramuscular dissection and gives predictable results with low complication rates. Intramuscular gluteoplasty with gluteal implants offers predictable, aesthetically pleasing results without contour irregularities and only a low incidence of major complications.

Bases Anatómicas de la Gluteoplastía Dinámica / Anatomical Basis of the Dinamic Gluteoplaty

La disrupción anatómica del esfínter es el mecanismo más común de incontinencia fecal. La creación de un mecanismo esfinteriano con control voluntario permite mantener la contracción en el reposo o durante los movimientos y es uno de los principios fisiológicos y quirúrgicos para la continencia. Esta corrección puede realizarse mediante la transposición de músculo glúteo mayor alrededor del ano y recrear así un esfínter voluntario. La gluteoplastía dinámica consiste en la colocación de un marcapasos que permite la estimulación eléctrica crónica intermitente del músculo esquelético, resultando en la adaptación de la contractilidad basal. El objetivo del trabajo consiste en el estudio anatómico de la longitud in situ y esqueletizado del fascículo inferior del músculo glúteo máximo, de su principal pedículo nervioso, la altura en la cual penetra al músculo desde el cóccix, y la longitud de su rama más distal para finalmente, proponer variantes técnicas para este procedimiento. Se disecaron 21 regiones glúteas de ambos lados de cadáveres frescos y formolizados al 10% de ambos sexos. La longitud del fascículo muscular sin esqueletizar osciló entre 17,8 y 19,65 cm, y esqueletizado entre 23,9 y 20.7 cm. La distancia de penetración del nervio principal fue entre 11,25 10,2 cm y la del nervio más medial se situó promedialmente entre 8,72 y 5,97 cm. La máxima longitud adquirida por el nervio principal hasta su rama más distal, osciló entre 10,4 y 9,2 cm. El fascículo inferior posee una longitud final que permite rodear completamente al ano e incluso, llegar al isquion contralateral hechos que apoyan el uso de este músculo en las transposiciones para la corrección de las incontinencias anales, sin la necesidad de realizar abordajes desmedidos y lejanos, permitiendo a su vez, el uso de un músculo de la región, evitando tracciones del pedículo neurovascular y la consiguiente isquemia luego del procedimiento quirúrgico. Se proponen tres técnicas para ...

The anatomical disruption of the sphincter is the most common mechanism of fecal incontinence. The creation of an sphincter mechanism with voluntary control allows to maintain the contraction during rest or movements and is one of the physiological and surgical principles of continence. This correction can be made by the gluteus maximus muscle transposition around the anus recreating a voluntary sphincter. The dynamic gluteoplasty consists in the positioning of a nerve stimulator that allows the intermittent chronic electrical stimulation of the skeletal muscle resulting in the adaptation of the basal contractility. The objective of the work is the anatomic study of the inferior fascicle of the gluteus maximus muscle (its length in situ and squeletized) and of its main nervous pedicle (the height in which penetrates the muscle from coccyx, and the length of its distal branch) so as to propose technical changes for the procedure. Twenty and one gluteus regions of both sides from fresh and formalized cadavers of both sexes were dissected. The length of muscular fascicle without squeletized oscillated between 17.8 and 19.65 cm, and squeletized between 23.9 and 20.7 cm. The distance of penetration of the main nerve was between 11.25 and 10.2 cm and the one of the most internal nerve was located promedially between 8.72 and 5.97 cm. The maximun length acquired by the main nerve until its distal branch oscillated between 10.4 and 9.2 cm. The inferior fascicle has a final length that allows to surround completely the anus or even to reach the contralateral isquion, facts which support the use of this muscle in the transpositions for the correction of the anal incontinence, without making excessive or distant boardings, allowing as well the use of a muscle from the region, avoiding tractions of neurovascular pedicle and the consequent isquemia after the surgical procedure. Three technical changes for the rotation of flap are proposed.
