摘    要:目的:探讨以乳突切迹和翼钩为基点的侧颅底分区新方法。方法:在乳突切迹后缘、翼钩、枕骨大孔前缘中点和颧根四个结构间相互连线,区分侧颅底并测量连线的长度。结果:乳突切迹与侧颅底重要结构的关系密切,切迹后缘与翼钩连线和正中线将侧颅底分成内、外侧两个大的三角区,每个区再分成前后两个三角区共四个三角区,即腭和颞下三角、咽三角、关节和听三角、血管神经三角,其中血管神经三角的三边长度左右侧分别为(74.52±5.47)mm和(74.66±5.41)mm、(59.77±3.84)mm和(59.67±3.56)mm、(42.23±3.11)mm和(42.48±2.60)mm。结论:本研究提供了新的侧颅底分区方法,且血管神经三角的区域划分更为科学,为临床侧颅底手术入路和定位提供了解剖学参考。

Abstract:Objective: To explore the new method of the mastoid notch and pterygoid hamulus in the lateral skull base partition.Methods: Connect the four structure points: posterior margin of the mastoid notch,pterygoid hamulus,midpoint of anterior margin of foramen magnum and zygomatic root,classify the lateral skull base and measure the length of the connection.Results: Mastoid notch have close relationship with the vital structures of the lateral skull base.The line connecting posterior margin of the mastoid notch and pterygoid hamulus and the midline divided the lateral skull base into the inner and outer two large triangular zones,each subdivided into front and back two triangular areas,a total of four triangle,that is,palatum and temporal triangle,pharyngeal triangle,joint and listen tri-angle,vessels and nerves Triangle,in which the length of left and right side of the triangle's three sides were 74.52 ± 5.47 mm and 74.66 ± 5.41mm,59.77 ± 3.84 mm and 59.67 ± 3.56mm,42.23 ± 3.11mm and 42.48 ± 2.60mm.Conclusion: This study provides a new method of lateral skull base partition.The regional division of neurovascular triangle is more scientific,and it provides the anatomical ref-erence for positioning lateral skull base surgical approaches.
Keywords:Mastoid Incisure  Pterygoid Hamulus  The Lateral Skull Base  Partition
