Abstract

Purpose

The aim of this study was to characterize the origin and course of the zygomaticus major muscle (Zmj) with its topographic relationships with the nasal ala, tragus, philtrum, and lateral canthus.

Methods

The Zmj was examined in 50 specimens of 25 embalmed adult Korean cadavers. Facial muscles were dissected to expose the origin and course of the Zmj in 48 specimens of 24 cadavers. The 25th cadaver was sectioned to obtain images of the Zmj.

Results

The positional relationships of the Zmj origin with the nasal ala and the tragus were classified into three categories. A horizontal line through the center of the Zmj origin and the nasal ala passed through the tragus in 20 of 48 specimens (41.7%), the intertragic notch in 18 specimens (37.5%), and above the tragus in 10 specimens (20.8%). In a horizontal section of the head, the Zmj origin was located near the level of the nasal ala and tragus. In a coronal section of the head, the fibers of the Zmj arising at its origin were located close to the zygomatic bone, lateral to the zygomaticus minor muscle.

Conclusion

By combining dissection with the analysis of sectioned images and ultrasound images of the Zmj, this study has yielded positional information for easily predicting the location of the origin and the course of the Zmj and its related structures underlying the skin.

大颧骨的起源和走向与鼻翼、鼻小柱、咽鼓管和外侧鼻翼的位置关系，用于美学治疗和手术

目的研究颧大肌(Zmj)的起源和走向，以及它与鼻翼、耳屏、中部和外眦的地形关系。方法对25具朝鲜族成人尸体50具标本进行Zmj检测。我们解剖了24具尸体48例的面部肌肉，揭示了Zmj的起源和走向。对第25具尸体进行切片以获得Zmj的图像。结果Zmj起源与鼻翼、耳屏的位置关系可分为三类。48例标本中有20例(41.7%)经Zmj原点中心至鼻翼的水线经耳屏，18例(37.5%)经眶间切迹，10例(20.8%)经耳屏以上。在头部的水平切面上，Zmj起源于鼻翼和耳屏附近。在头部的冠状切面上，起源于Zmj的纤维位于颧骨附近，颧小肌外侧。结论本研究通过解剖结合Zmj的切片图像和超声图像分析，获得了Zmj的位置信息，可方便地预测Zmj的起源位置、病程及皮肤下相关结构。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
