BACKGROUND/AIM: Facial nerve paralysis is the most worrying parotid surgery complication. Little attention has been paid to the facial nerve trunk, especially in children. Pathological variations, tumors, and anatomic variations of the facial nerve may cause parotid and facial nerve surgery difficulties. This study describes the facial nerve trunk.
We measured the facial nerve trunk from 8 female and 8 male fetus cadavers aged 21.0 to 35.5 gestational weeks. The locations and positions of the trunks were described. The length of the facial nerve trunk (K) was measured and bifurcation and trifurcation of the trunk was examined. Values were analyzed separately for right and left sides and for male and female fetuses.
The most common facial nerve trunk type was bifurcation (81.25%), followed by trifurcation (18.75%). K was 11.59 + 2.80 mm in the total fetuses. There was no significant difference between K measurements.
Facial nerve injury during parotid surgery is a main cause of pediatric facial paralysis. There are few previous descriptions of the facial trunk in children. K must be accurately known in any surgical procedure planned for the area. The main furcation of the facial nerve should also receive special attention.
背景/目的：面神经麻痹是最令人担忧的腮腺手术并发症。很少关注面神经干，尤其是在儿童中。面神经的病理变异、肿瘤和解剖变异可能导致腮腺和面神经手术困难。本研究描述了面神经干。
我们测量了 8 名女性和 8 名男性胎儿尸体的面神经干，年龄为 21.0 至 35.5 孕周。描述了干的位置和位置。测量面神经干的长度（K），并检查干的分叉和三分叉。分别分析右侧和左侧以及男性和女性胎儿的值。
最常见的面神经干类型是分叉（81.25%），其次是三分叉（18.75%）。总胎儿的 K 值为 11.59+2.80mm。K 值之间无显著差异。
腮腺手术过程中的面神经损伤是儿童面神经麻痹的主要原因。以前很少有关于儿童面神经干的描述。在计划该区域的任何手术时，必须准确了解 K 值。面神经的主要分支也应特别注意。
