作者在31例(62侧)男性成人的标本上,以颧弓下缘与下颌关节突前缘的交点到下颌角向前下突出处的连线为Y抽,并以通过Y抽中点,而且与之相垂直的线为X抽。测出了(单位为mm):1.面神经干分叉点的投影坐标平均值是(-20.48±3.57,11.92±3.51)。2.面神经的5组分支出腮腺缘的定位投影:①颞支组的平均值为(0.66±坐标7.82,33.05±4.67),②颧支组的平均坐标值为(12.40±6.83,25.25±5.13);③颊支组中的B_1组是(12.33±5.71,18.77±6.54),B_2组是(2.59±6.91,-1.38±8.71);④下颌缘支组的平均坐标值为(-8.94±4.01,-18.18±5.70);⑤颈支组的平均坐标值是(-15.95±3.92,-24.81±6.54)。
The author of 31 cases (62 sides) male adult specimens, the lower edge of the zygomatic arch and the mandibular joint front to the junction of mandibular angle to the front under the projection of the connection for the Y pumping, and through the pumping Y midpoint, And the vertical line with the X pumping. Measured in units of mm: 1. The mean projection coordinates of facial nerve trunk bifurcation points are (-20.48 ± 3.57, 11.92 ± 3.51). (2) The projection of 5 components of facial nerve on parotid margin: (1) the average value of temporal branch group is (0.66 ± 7.82,33.05 ± 4.67); ②The average coordinate of zygomatic branch group is (12.40 ± 6.83,25.25 ± 5.13 ) In the buccal branch group was (12.33 ± 5.71, 18.77 ± 6.54) in the buccal branch group and (2.59 ± 6.91, -1.38 ± 8.71) in the B_2 group. The average coordinate value of the mandibular margin branch group was (-8.94 ± 4.01) , -18.18 ± 5.70); ⑤The mean coordinate value of cervical support group was (-15.95 ± 3.92, -24.81 ± 6.54).
