The most recent study of the relationship between the maxillary artery and the lateral pterygoid muscle was published in this journal in 2008.(1) Given the controversy surrounding this relationship, our purpose was to present data gathered from New Zealand caucasoid cadavers over several years.
Both sides of 92 caucasoid adult cadaveric heads (45 male, 47 female) were dissected by 3 successive years of third-year medical students and second-year dental students. The infratemporal approach was used. Once the dissections reached the plane of the maxillary artery and lateral pterygoid muscle, their relationship was recorded, together with exemplary images. Sexual and symmetrical differences were noted.
In the 53 cases where bilateral dissection had been successful, the second part of the maxillary artery was found superficial to the lower head of the lateral pterygoid muscle in 30 cases (57%)-in 70% of the males and 39% of the females. One male and 1 female presented bilateral asymmetry.
The finding of 2 cases of bilateral asymmetry among the 53 bilaterally dissected cadavers led to the consideration of each "hemi-head" as a single entity. This increased the sample size. Statistical analysis of the data, systematically broken down by sex and by side, showed that the second part of the maxillary artery is more likely to lie deep to the lower head of the lateral pterygoid muscle in females than in males, and that "side" is irrelevant.
关于上颌动脉与翼外肌之间关系的最新研究于2008年发表在本杂志上。(1)鉴于围绕这种关系存在的争议，我们的目的是展示多年来从新西兰白种人尸体收集的数据。
92具白种人成年尸体头部（45例男性，47例女性）的两侧由三年级医学生和二年级牙科学生连续三年进行解剖。采用颞下进路。一旦解剖到达上颌动脉和翼外肌平面，就记录它们的关系，并附上示例图像。记录性别和对称性差异。
在53例双侧解剖成功的病例中，上颌动脉第二段位于翼外肌下头浅面的有30例（57%）——男性为70%，女性为39%。1例男性和1例女性表现为双侧不对称。
在53例双侧解剖的尸体中有2例双侧不对称，这使得将每个“半侧头部”视为一个单独的个体。这增加了样本量。按性别和侧别系统分类对数据进行统计分析表明，上颌动脉第二段在女性中比在男性中更有可能位于翼外肌下头的深面，且“侧别”无关紧要。
