摘要
目的:为临床上充分矫正上睑外侧肥厚臃肿下垂提供临床解剖学依据。方法:选用防腐固定标本15例(30侧),并对12例(24侧)上睑外侧臃肿肥厚下垂病例行上睑成形术,观察上睑眼轮匝肌下脂肪的位置、范围、厚度,与眶隔脂肪的关系。结果:上睑眼轮匝肌下脂肪是位于上睑部眼轮匝肌下,睑板筋膜及眶隔筋膜前的一层纤维脂肪层,是眉脂肪垫向下的延续,范围相当于整个上睑的大小,该脂肪厚薄不一,薄者如同一层筋膜,最厚者约4mm。上睑眼轮匝肌下脂肪厚者,眶隔脂肪反而不显,上睑眼轮匝肌下脂肪薄者,眶隔脂肪反而明显。结论:上睑外侧肥厚臃肿下垂除了与眶隔脂肪过多、脱垂有关外,还与上睑眼轮匝肌下脂肪肥厚有关。
Objective： To investigate anatomic characteristics ofsuborbicularis oculus fat and orbital fat of the upper eyelid and make clear the anatomic mechanisms of thickening and ptosis of the lateral upper eyelid. Methods： The anatomic features of suborbicularis oculus fat and orbital fat were observed on 15 antiseptic cadaveric specimens and 12 cases suffering from fullness and heaviness and ptosis of the lateral upper eyelid, who asked for blepharoplasty. Results：. The upper eyelid suborbicularis oculus fat pad could be defined as the layer of fibrofatty soft tissue deep to the orbicularis oculus muscle,superficial to the orbital septum, The extension of the fat pad was equal to that of the upper eyelid. The thickness of the fat pads was variable,with the most of 4mm. For those cases with thickening suborbicularis oculus fat, their orbital fat was always limited,otherwise the orbital fat was obvious, Conchusions： The suborbicularis oculus fat and the orbital fat of the upper eyelid both contribute to thickening and heaviness and ptosis of the lateral upper eyelid.
