The aim of this study was to elucidate the intramuscular course of the inferior gluteal nerve in the gluteus maximus muscle and its association with augmentation gluteoplasty. Twenty buttocks of 10 Korean adult cadavers (age range: 47-87, 7 men and 5 women) were used for the study. The inferior gluteal nerve (IGN) was traced from the infrapiriform foramen at the deep surface of gluteus maximus (GM) until the nerve thickness became 0.3 mm. The depth of the IGN was measured and the relative depth of the nerve was calculated according to the thickness of the GM at 15 points. The muscle thickness varied according to its location. The medial part (17.1-18.1 mm) was thicker than the lateral (14.5-15.7 mm) or inferior parts (14.5-14.7 mm). The IGN runs deep through the GM (59%-82% of muscle thickness). Except for below the Coccyx-Greater trochanter line, where the IGN was located (59%-62% depth), the IGN was traced to 63-82% of the depth in the GM. The IGN ran relatively superficial (below 70%) in the medial part of the GM, and was a little deeper (above 70%) in the lateral part. There results of this study showed that intramuscular augmentation gluteoplasty could be performed safely unless intramuscular dissection is performed too deeply.
本研究的目的是阐明臀下神经在臀大肌内的走行及其与隆臀术的关系。本研究使用了10具韩国成年尸体（年龄范围：47 - 87岁，7名男性和5名女性）的20个臀部。从臀大肌（GM）深面的梨状肌下孔开始追踪臀下神经（IGN），直至神经厚度变为0.3毫米。测量IGN的深度，并根据GM在15个点的厚度计算神经的相对深度。肌肉厚度因位置而异。内侧部分（17.1 - 18.1毫米）比外侧（14.5 - 15.7毫米）或下部（14.5 - 14.7毫米）更厚。IGN在GM内深层走行（占肌肉厚度的59% - 82%）。除了在尾骨 - 大转子线以下IGN所在位置（深度为59% - 62%）外，IGN在GM内的深度可追踪至63% - 82%。IGN在GM内侧部分走行相对表浅（低于70%），而在外侧部分稍深（高于70%）。本研究结果表明，除非肌肉内解剖过深，否则肌肉内隆臀术可以安全进行。
