The aim of this study is to elucidate the thickness and tension of the gluteal aponeurosis (GA) as related to subfascial gluteal augmentation. Twenty buttocks from 10 Korean fresh cadavers (age range: 69-92 years, five men and five women) were dissected. Five radial lines were made from the greater trochanter (GT) to the highest point of origin of the gluteus maximus muscle (GM), the posterior inferior iliac spine (PSIS), the piriformis line (P), the coccyx (Co) and the ischial tuberosity (IT). The upper four lines were intersected by three curvilinear lines that divided them by a quarter, half and three-quarters ratios, and the lowest line was divided by a third ratio and a two-thirds ratio. At the 14 intersecting points, the force needed to break the 6 mm width of the GA was measured. The thickness of the GA was also measured with a digital caliper. The GA was widest at the GT-Co line (161.7±15.8 mm), and it was narrowest at the GT-IT line (106.5±21.2 mm). At most of the points (12 among the 14 points), the breaking strength of the GA was greater than 20 Newtons (N). The breaking strength of the GA did not vary significantly according to the locations (P=0.568, anova). The breaking strength of the males (22.8±6.6 N) was significantly greater than that of the females (20.3±7.5 N, P=0.003, t-test). The thickness of the GA varied according to the locations (0.4±0.2 mm to 0.7±0.3 mm). The thickness of the GA of the upper part (GT-GM line: 0.64±0.24 mm; GT-PSIS line: 0.66±0.23 mm; GT-P line: 0.66±0.24 mm) was significantly greater (P=0.040, 0.017, 0.018, respectively) than that of the lower part (GT-IT line: 0.49±0.18 mm). The GA of the males (0.70±0.23 mm) was significantly thicker than that of the females (0.53±0.21 mm, P<0.001, t-test). We conclude that the GA is capable of holding gluteal implants in the proper position, as the average force to break up the 6 mm width of the GA in females was greater than 20 N.
本研究旨在阐明与筋膜下臀肌隆乳术相关的臀大肌筋膜（GA）的厚度和张力。从 10 具韩国新鲜尸体（年龄范围：69-92 岁，男性 5 例，女性 5 例）的臀部解剖出 20 个臀部。从大转子（GT）到臀大肌（GM）最高点、后下髂嵴（PSIS）、梨状肌线（P）、尾骨（Co）和坐骨结节（IT），共做了 5 条径向线。前 4 条线与 3 条曲线相交，将每条线分为四分之一、一半和四分之三的比例，最下面的线分为三分之一和三分之二的比例。在 14 个交点处，测量了打破 6 毫米宽 GA 所需的力。使用数字卡尺测量 GA 的厚度。GA 在 GT-Co 线最宽（161.7±15.8mm），在 GT-IT 线最窄（106.5±21.2mm）。在大多数点（14 个点中的 12 个点），GA 的断裂强度大于 20 牛顿（N）。GA 的断裂强度与位置无关（P=0.568，方差分析）。男性（22.8±6.6N）的 GA 断裂强度明显大于女性（20.3±7.5N，P=0.003，t 检验）。GA 的厚度与位置有关（0.4±0.2mm 至 0.7±0.3mm）。GA 的上半部分（GT-GM 线：0.64±0.24mm；GT-PSIS 线：0.66±0.23mm；GT-P 线：0.66±0.24mm）明显大于下半部分（GT-IT 线：0.49±0.18mm，P=0.040，0.017，0.018）。男性（0.70±0.23mm）的 GA 明显比女性（0.53±0.21mm，P<0.001，t 检验）厚。我们得出结论，GA 能够将臀肌植入物固定在适当的位置，因为女性打破 6mm 宽 GA 所需的平均力大于 20N。
