geniculate ganglion

Experimental Study on Methods for Primary Culture of Geniculate Ganglion Cells and Spiral Ganglion Cells of Adult Guinea Pigs

成年豚鼠膝状神经节及螺旋神经节细胞的体外培养

The cochleariform process was an important landmark in middle ear surgery . The distance between the cochleariform process and geniculate ganglion was 2.79 ± 0.39 mm .

匙突是耳科手术的重要解剖标志，膝状神经节至匙突的距离经测量为2.79±0.39mm。

Objective : To investigate anatomy of geniculate ganglion in adult guinea pig .

目的：研究成年豚鼠面神经膝状神经节解剖。

Neurons are identified by immunofluorescence method . Result : Geniculate ganglion of adult guinea pig has no obvious enlargement in diameter compared with facial nerve trunk .

选取状态良好的生长期进行神经元细胞的免疫荧光鉴定。结果：成年豚鼠的膝状神经节与面神经主干相比没有明显膨大，不易定位。

Facial nerve consists of motor and sensory fibers . Sensorial neurons of facial nerve , innervating the posterior auricle , are located in the geniculate ganglion .

面神经包含运动神经纤维和感觉神经纤维，支配耳廓后部的面神经感觉神经元位于膝状神经节。

Result : It is demonstrated that 8.3 % geniculate ganglion and labyrinth segment of facial nerve Variation which distance from hiatus of facial nerve to geniculate ganglion is distinct .

结果：8.3%面神经迷路段和膝状神经节骨管型缺如，面神经裂孔到膝神经节的距离变异较大。

Results : ① The greater superficial petrosal nerve was an important landmark in drilling petrous bone . Backing it we can find out the intrapetrous carotid artery ( ICA ), cochlear and geniculate ganglion ( GG );

结果：①岩大神经是磨除颞骨岩部十分重要的标志，通过它可以定位岩部颈内动脉、耳蜗和膝状神经节；

Methods : 12 cases of traumatic facial paralysis undergone surgical treatment . 3 cases showed injuries to the labyrinthine segment of nerve and geniculate ganglion , 6 cases to tympanic segment , 4 cases to mastoid segment and 1 case to intracranial segment .

方法：对12例外伤性面瘫的病例施行手术治疗，损伤部位于面神经迷路段及膝状神经节周围3例次、水平段6例次、垂直段4例次、颅内段1例次。
