鼻唇沟区域解剖学研究

目的对颌面整形美容外科提供形态学依据。方法对２０侧成人新鲜尸头行１０％福尔马林血管灌注固定后，在手术放大镜下进行形态学观测。结果①首次对少数国人与鼻唇沟区域相关的各表情肌逐块进行长、宽、厚的显微解剖测量。②测得鼻唇沟内侧脂肪厚度为１３ｍｍ，外侧为４５ｍｍ。③鼻唇沟内侧真皮层有肌纤维附着，外侧也有稀少肌束附着。④面部表浅肌肉之间不但存在腱膜，还由筋膜、肌肉、腱膜共同构成一个立体网状结构。结论进一步证实了有关ＳＭＡＳ中央腱的理论假说。

An anatomical study of the nasolabial fold region

Objective\ This study of the nasolabial fold is to provide the morphological basis for maxillofacial plastic and cosmetic surgery.Z]Methods\ Twenty fresh adult cadavers heads were dissected with microsurgical technique and the structure of the nasolabial region was observed and measured. Results The data about the length,width and thickness of each mimetic muscle were obtained and presented in the paper.The medial and lateral subcutaneous fat of the nasolabial groove was 1.3 mm and 4.5mm in thickness respectively.There existed muscle fiber attachments in the medial dermis of nasolabial groove, and in the lateral dermis there were only a few muscle bundle attachments.Among the superficial facial muscles there were not only fasciae but also aponeuroses.The muscles,fasciae and aponeuroses composed a threedimensional reticular structure. Conclusion\ This study gave a further support to the theoretical hypothesis of SMAS intermediate tendon.
