The objective of the current study was to retrospectively examine the morphological magnetic resonance imaging (MRI) characteristics of the gluteus maximus of buttock augmentation at levels of predetermined anatomic points.
The present study was a retrospective cross-sectional study. Adult women who underwent high-quality MRI scanning at Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to January 2021 were included in this work. The transverse MRI data measured at the inferior point of the sacroiliac joint, just above the femoral head, and at the ischial tuberosity were collected and statistically analyzed.
Fifty-two cases (104 sides of female gluteus maximus) were included in the final analysis. The A point (surgery starting point) were 54.4±6.34 mm, 54.91±5.57 mm, and 73.91±5.57 mm away from the posterior midline at the level of inferior point of the sacroiliac joint, just above the femoral head, and at the ischial tuberosity, respectively. Accordingly, the thickness of the muscle at these locations was 16.0±4.17 mm, 23.4±4.40 mm, and 24.6±7.58 mm, respectively. The diameter of the implant did not exceed 14.18±1.22 cm. In addition, the gluteus maximus at the lowest point of the sacroiliac joint and above the femoral head exhibited an arc structure, which needs to be tilted to the deep plane during separation.
Dissimilar from previous experience of blind dissection, the gluteus maximus muscle can be more scientifically and reasonably dissected using the indexes for gluteus augmentation supplied in this study.
本研究的目的是回顾性地研究在预定解剖点水平下用于臀部增大的臀大肌的形态磁共振成像（MRI）特征。
本研究为回顾性横断面研究。纳入了2018年1月至2021年1月在中山大学孙逸仙纪念医院接受高质量MRI扫描的成年女性。收集在骶髂关节下点、股骨头上方和坐骨结节处测量的横向MRI数据并进行统计分析。
最终分析纳入了52例（104侧女性臀大肌）。A点（手术起始点）在骶髂关节下点、股骨头上方和坐骨结节水平分别距离后正中线54.4±6.34mm、54.91±5.57mm和73.91±5.57mm。相应地，这些位置的肌肉厚度分别为16.0±4.17mm、23.4±4.40mm和24.6±7.58mm。植入物直径不超过14.18±1.22cm。此外，骶髂关节最低点和股骨头上方的臀大肌呈弧形结构，分离时需要向深层平面倾斜。
与以往的盲目解剖经验不同，利用本研究提供的臀部增大指标，可以更科学合理地解剖臀大肌。
