The aim of this study was to describe the course of the buccal nerve and its relationships with the temporalis muscle during the prenatal period. Serial sections of 90 human fetal specimens ranging from 9 to 17 wk development were studied by light microscopy. Each fetal specimen was studied on both right and left sides, making a total of 180 cases for study. A 3-D reconstruction of the region analysed in one of the specimens was made. In 89 cases the buccal nerve was located medial to the temporalis muscle; in 73 cases it penetrated the muscle; in 15 cases it lay in a canal formed by the muscle fibres and was covered by fascia, and finally, in 3 cases it was a branch of the inferior alveolar nerve. The study has revealed that in a large number of cases the buccal nerve maintains an intimate association with the temporalis muscle.
本研究的目的是描述颊神经在胎儿期的走行及其与颞肌的关系。对90例发育9至17周的人类胎儿标本进行连续切片，采用光学显微镜观察。对每个胎儿标本的左右两侧进行研究，共计180例。对其中一个标本分析的区域进行了三维重建。在89例中，颊神经位于颞肌内侧；73例中，颊神经穿过颞肌；15例中，颊神经位于由肌纤维形成并被筋膜覆盖的管道内；最后，在3例中，颊神经是下牙槽神经的分支。该研究表明，在大量病例中，颊神经与颞肌保持密切联系。
