摘要
目的 :为海绵窦手术避免脑神经损伤提供解剖学依据。方法 :对 17例成年头部标本的海绵窦内脑神经的位置、走行、毗邻进行解剖学观察。结果 :动眼神经入窦点在后床突的前外侧 7.8± 2 .1mm ,在颈内动脉床突上段后方 5 .0± 2 .0mm处。滑车神经窦内段长度为 10 .1± 3 .9mm ,其走行可分为窦内直行、中份凸向眼神经、“S”型双弯曲、前 1/2段凸向眼神经 4种类型。眼神经在窦内的长度为 15 .8±6.2mm。展神经在窦内为单干者占 5 2 .9% ( 18侧 ) ;2干者占 2 9.4% ( 10侧 ) ;3干者占 17.7% ( 6侧 )。结论 :滑车神经的走行变化较大 ,经Pakinson三角行海绵窦手术时 ,应注意保护滑车神经。切开海绵窦上壁分离窦腔时 ,应注意保护经上壁入窦的动眼神经。
Objective:To provide anatomic data for avoiding damage the cranial nerves in cavernous sinus during cavernous operation.Methods:The location, course and syntopy of cranial nerves in cavernous sinus were observed on 17 adult cadaverical heads (34 sides of cavernous sinuses).Results:The oculomotor nerve entered into cavernous sinus at 7.8± 2.1 mm anterolateral to posterior clinoid process and 5.0±2.0 mm posterior to superior segment of clinoid process of internal carotid artery.The length of trochlear nerve and ophthalmic nerve in cavernouse sinus was 10.1±3.9 mm and 15.8 ± 6.2 mm respectively,and trochlear nerve has four type of courses.There were 53.9% of abducent nerve had one stem in cavernous sinus,29.4% of them had two stems and 17.7% of them had 3 stems.Conclusions:The trochlear nerves had the most various courses and it should be protected during the operation through Pakinson′s triangle area.The oculomotor nerve should be protected during the operation of incising superior wall of cavernous sinus.
