Espesor normal del músculo glúteo mayor en mujeres chilenas: una guía para el aumento de glúteo con implantes / Normal thickness of gluteus maximus muscle in Chilean women: a guide for buttock augmentation with implants

Introducción: El aumento de glúteo con implantes ha tomado fuerza en los últimos años con la aparición de la técnica intramuscular, que sugiere la creación de un bolsillo en el espesor del músculo glúteo mayor a 3 cm de profundidad. Por diferencias étnicas en el glúteo de pacientes chilenas, es necesario realizar mediciones para caracterizar el grosor del músculo glúteo mayor en nuestra población. Nuestro objetivo es conocer el espesor promedio del músculo glúteo mayor en mujeres chilenas. Material y método: Se diseñó un estudio descriptivo, retrospectivo, midiendo el espesor del músculo glúteo en todas las tomografías de abdomen y pelvis en prono, en mujeres entre 18 y 65 años, desde el 1 de enero al 31 de diciembre del año 2015 en el Hospital Clínico de la Universidad de Chile. Se determinó la asociación con la edad, el peso, la talla, el índice de masa corporal (IMC) y el espesor de la grasa abdominal y glútea de las pacientes. Resultados: El promedio del espesor del músculo glúteo derecho fue de 3,85 cm (IC 95%: 3,76-3,95) y el del glúteo izquierdo fue de 3,84 cm (IC 95%: 3,75-3,92). Existió asociación positiva entre el peso y el espesor del músculo, y entre el IMC y el espesor del músculo. Estas asociaciones fueron estadísticamente significativas. Discusión: Por las características de nuestra población, en la que el espesor del músculo glúteo mayor es menor que el descrito en la literatura, el bolsillo en el músculo debe ser realizado con precaución y a una profundidad menor a la descrita.

Introduction: Buttock augmentation with implants has become more frecuent in recent years with the emergence of the intramuscular technique, which suggests creating a pocket in the thickness of the gluteus maximus muscle, 3 cm deep. Ethnic differences in the gluteus of Chilean patients, makes measurements necessary to characterize the thickness of the gluteus maximus muscle in our population. Our objective is to know the average thickness of the gluteus maximus muscle in Chilean women. Material and method: A descriptive, retrospective study was designed by measuring the thickness of the gluteal muscle in all abdominal CT scans in prone position, in women aged 18 to 65, from January 1th, to December 31, 2015 at the Clinical Hospital the University of Chile. Association with age, weight, height, body mass index (BMI) and abdominal and gluteal fat thickness of patients was determined. Results: The average thickness of the right gluteal muscle was 3.85 cm (95% CI: 3.76-3.95) and the left gluteal muscle was 3.84 cm (95% CI: 3.75-3.92). There was a positive association between weight and thickness of the muscle, and between BMI and thickness of the muscle, these associations were statistically significant. Discussion: In our population, the thickness of the gluteus maximus is less than described in the literature, pocket in the muscle should be done with caution and shallowest than described.

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.
