The aim of this study was to elucidate the branching patterns of the facial nerve inside the parotid gland. The relations between the branchings of the facial nerve were investigated on 27 children's faces. The trunk of the facial nerve had a length of about 0.9 cm (0.6-1.2 cm). According to the branching patterns of the facial nerve and to the communication of branches, they were grouped into 5 types. The straight branching was seen in 14 (52%) out of 27 cases (Type I). Two (7%) out of 27 cases had a loop involving the zygomatic branch (Type II). There were anastomoses between buccal and zygomatic branches in 2 (7%) of cases (Type III). There were multiple anastomoses among branches in 8 (30%) of the cases (Type IV). Only one (4%) out of 27 cases had two trunks, one thin and one thick (Type V). 13 of the cases were bilaterally studied. Seven out of 13 (53%) were bilaterally same type and 6 out of 13 (47%) were bilaterally different type. The branching groups of Type I and IV were seen more in children aged 0-2 and 4-5 compared to the other types, respectively. As the child gets older, the incidence frequency of anastomoses in the facial nerve increases with age.
本研究的目的是阐明面神经在腮腺内的分支模式。在27例儿童面部研究了面神经分支之间的关系。面神经主干长度约为0.9厘米（0.6 - 1.2厘米）。根据面神经的分支模式和分支之间的连通情况，将其分为5种类型。27例中有14例（52%）出现直线型分支（I型）。27例中有2例（7%）出现涉及颧支的袢型（II型）。2例（7%）的颊支和颧支之间存在吻合（III型）。8例（30%）的病例分支之间存在多处吻合（IV型）。27例中只有1例（4%）有两条主干，一条细一条粗（V型）。对其中13例进行了双侧研究。13例中有7例（53%）双侧类型相同，6例（47%）双侧类型不同。与其他类型相比，I型和IV型分支组在0 - 2岁和4 - 5岁儿童中分别更为常见。随着儿童年龄增长，面神经吻合的发生率随年龄增加。
