目的通过对眶颊联合区域进行解剖学研究,探讨眶颊联合老化后形成眶颊沟的发生机制.方法选取13具(26侧)10％甲醛固定的成人尸头标本,其中男9具(18侧),女4具(8侧),年龄22～78岁.应用显微手术器械在10倍的解剖显微镜下逐层解剖眼周,重点解剖下睑眶部和眶外侧,了解并描述各区的解剖学层次,解剖显露眶外侧增厚区,认真记录眶外侧增厚区解剖学位置并照相保存.结果 (1)眶外侧区层次:皮肤层、皮下脂肪层、眼轮匝肌层、眶外侧增厚区、颞中筋膜层、骨膜层.(2)眶外侧增厚区:起于眶外侧缘向外侧走行在颞中筋膜表面,成三角形,三角形的顶角距外眦角25.24～37.20 mm.眶外侧增厚区与颞中筋膜紧密粘连区也成三角形,顶点距外眦角(9.28±0.45) mm.向内侧走行在眼轮匝肌下眶隔表面,分为上、下睑部,下睑部成横V形,V上臂与睑板前筋膜粘连,距外眦角21.69～37.21 mm.下臂与眶下缘粘连,距外眦角垂线(13.55±0.52) mm.V顶点距外眦角垂线(11.35±0.27) mm.结论眶颊联合老化后形成眶颊沟的主要原因是皮下脂肪层和颞中筋膜层的脂肪萎缩所致.

Objective To identify the anatomical basis for aging orbit-malar fold forming orbitmalar groove and its underlying mechanism.Methods Thirteen cadavers (26 hemifaces) were dissected in this study (9 male and 4 female heads).All specimens were fixed in 10％ formalin,with age ranges from 22 to 78 years.The lateral orbital region was dissected in layers by mieroinsrument using 10 X loupe magnification,especially at the palpebral and the lateral orbital part,and then the anatomy layer was described; the lateral orbital thickening (LOT) was performed carefully to evaluate whether there were multiple anatomical contributions to anatomy.Anatomic observations were systematically recorded,sketched,and photographically documented.Results The lateral orbital layers included skin,subcutaneous adipose tissue,orbicularis oculi muscle,middle temporal fascia,and periosteum.The lateral orbital thickening was a triangular condensation of fascia,which extended over the lateral orbital rim onto the adjacent medial tem~ral fascia,the lateral orbital thickening was measured (9.28 ±0.45) mm in transverse width from Vertex triangle to lateral canchal,the inner part of the LOT sanwiched between orbibularis and obital septum,which consisted of upper lid and lower lid part,the lower lid part presented transverse V shape,the top part of the transverse V was adhesive to fascial tissue over tarsal plate.The distance to lateral canthus angular was 21.69-37.21 mm,and the under part was adhesive to low orbital rim the low arm distance to lateral canthus angular was (13.55 ±0.52) mm.Vertex of.V to lateral canthus angular vertical distance was (11.35±0.27) mm.Conclusions The reason why aging orbit-malar fold forms orbital-malar groove is the atrophy of the subcutaneous adipose tissue and the middle temporal fascia fat.
