摘要
目的探讨硬膜下岩前入路中精准定位岩前相关骨性结构的改良方法.方法选取10具干性颅骨并标记弓状隆起最高点(A)、岩尖(P)、岩浅大神经沟最外侧缘点(B)、棘孔最外侧缘点(C)、卵圆孔最外侧缘点(D)、三叉神经压迹最外侧缘点(E)和破裂孔的最外侧缘点(F).以A点为参照点,AP作为基线,分别测量AB、AC、AD、AE、AF连线的距离及各连线与基线形成锐角的角度.样本以均数及标准差分析,两侧数据采用t检验比较.结果 AB:左侧(11.61 ±2.31) mm、右侧(10.44±2.31) mm、t=1.084;AC:左侧(23.14±3.07) mm、右侧(21.08 ±2.67) mm、t=1.596;AD:左侧(24.95±2.82) mm、右侧(24.38±3.44) mm、t=0.408;AE:左侧(18.98 ±3.11) mm、右侧(19.21±3.09) mm、t=-0.164;AF:左侧(29.68±2.62) mm、右侧(29.25 ±2.77) mm、t=0.725./BAP:左侧(49.15±12.10)°、右侧(52.78 ±14.27)°、t=-0.624;∠CAP:左侧(43.98±6.95)°、右侧(48.73±8.02)°、t=-1.418;/DAP:左侧(38.68±4.81)°、右侧(41.48±3.14)°、t=-1.543;∠ EAP:左侧(21.93 ±5.29)°、右侧(25.94±6.43)°、t=-1.523;∠FAP:左侧(15.96 ±2.78)°、右侧(17.20±3.44)°、t=-0.882.两侧数据比较差异均无统计学意义(P>0.05).结论在硬膜下岩前入路中,此方法以弓状隆起最高点及岩尖为参照点,可以精准定位岩前相关骨性解剖标志,为确定相应的神经血管结构,磨除Kawase三角提供量化依据.
Objective To explore the improved method of precisely locating related bony structures in intradural anterior transpetrosal approach. Methods On the 10 dry skulls, the highest point of arcuate eminence (A), the petrous apex (P), the most lateral point of groove for the greater petrosal nerve (B), foramen spinosum (C), foramen ovale (D), trigeminal impression (E) and t foramen lacerum (F)were marked. Using point A as reference point and the line AP as the baseline, the distances of AB, AC, AD, AE and AF and the angles of ∠BAP,∠CAP,∠DAP,∠EAP and ∠FAP were measured. Samples were analyzed by mean and standard deviation, and the data on both sides were compared by t test. Results 1.AB:(11.61±2.31) mm (left), 10.44±2.31 mm (right), t=1.084;AC:(23.14±3.07) mm (left),(21.08±2.67) mm (right), t=1.596;AD:(24.95±2.82) mm (left),(24.38±3.44) mm (right), t=0.408;AE:(18.98±3.11) mm (left),(19.21±3.09) mm (right), t=-0.164;AF:(29.68±2.62) mm (left),(29.25±2.77) mm (right), t=0.725. 2.∠BAP:(49.15±12.10)°(left),(52.78±14.27)°(right), t=-0.624;∠CAP:(43.98±6.95)°(left),(48.73±8.02)°(right), t=-1.418;∠DAP:(38.68±4.81)°(left),(41.48±3.14)°(right), t=-1.543;∠EAP:(21.93±5.29)°(left),(25.94±6.43)°(right), t=-1.523;∠FAP:(15.96±2.78)°(left),(17.20±3.44)°(right), t=-0.882. There were no significant differences between the left and right sides (P>0.05). Conclusion Using point A and P as referent indexes, the bony structures which represent the corresponding nerves and blood vessels can be precisely located for grinding Kawase triangle via intradural anterior transpetrosal approach.
