PURPOSE
This cadaver dissection studied the relationship of the buccal branch of the facial nerve to the parotid duct and its relevance to surgical procedures in this area.
MATERIALS AND METHODS
Ten cadaveric heads (twenty sides) were dissected. The superficial tissues were removed, and the buccal branch of the facial nerve and the parotid duct were identified. The vertical and horizontal relationships were recorded and analyzed.
RESULTS
Eighty-five percent of the cadavers had a single buccal branch of the facial nerve, whereas 15% had two branches. In 75% of cases, the nerve was inferior to the duct as it emerged from the parotid gland, whereas in 25% of cases the nerve crossed the duct, usually from superior to inferior.
CONCLUSION
The buccal branch of the facial nerve has a close relationship with the parotid gland for over 2.5 cm after it emerges from the parotid gland; it normally lies inferior to the duct. This relationship is of importance in performing parotid gland surgery, parotid duct surgery, and some facial cosmetic surgery.
目的
本尸体解剖研究了面神经颊支与腮腺导管的关系及其在该区域手术操作中的相关性。
材料与方法
解剖了10具尸体头部（20侧）。去除浅表组织，识别出面神经颊支和腮腺导管。记录并分析其垂直和水平关系。
结果
85%的尸体有单支面神经颊支，而15%有两支。在75%的病例中，神经从腮腺穿出时位于导管下方，而在25%的病例中，神经跨过导管，通常是从上方到下方。
结论
面神经颊支从腮腺穿出后在超过2.5厘米的距离内与腮腺关系密切；它通常位于导管下方。这种关系在进行腮腺手术、腮腺导管手术和一些面部整形手术中具有重要意义。
