mastoidectomy

Methods : the anatomic relationship between the cross point ( a ) of the sigmoid and the transverse sinus and the asterion ( s ) , the cross point of the perpendicular and the horizontal ( b ) and point of the fissure of the occipital - mastoid at the fundus of the mastoid ( c ) were determined . then the length of a - s and b - c were measured . results : ( 1 ) the a point was lateral and inferior to the asterion , 10 . 8 + 1 . 1 mm on horizontal plane , 3 . 5 + 0 . 7mm on the longitude plane 方法:確定橫竇和乙狀竇的交界內下緣比點)和星點(枕乳縫和人字縫交叉點, s點)的解剖關系;乙狀竇垂直部和水平部交匯處內下緣舊點)和枕乳縫乳突基底水平處點)的關系。測量as和b c點的距離。結果: l橫竇和乙狀竇交點的位于星點外下方,橫斷面上,平均距離為10

Measurements for the following anatomical structures were obtained with the aid of a microscope , the distance between mastoid process and transverse process of the atlas , occipital condyle , and superior lateral loop ; the distances between the midline and the v3 at three levels : 1 ) the distal ( dural ) ring ; 2 ) the intersection with the anterior ramus of the c - 2 ; and 3 ) the upper level of the transverse foramen of the atlas ; the diameter of v3h at the origin of the muscular artery and at the sites of penetrating the dural ring ; the width of the v3 at the intersection with the anterior ramus of the c - 2 and at the sites of penetrating the transverse foramen of the atlas V _ 3h和v _ 3v各有兩個分支: v _ 3h分出肌動脈支和腦膜后動脈支; v _ 3v分出肌動脈支和根肌動脈支,第一、二脊神經發出的前后支分別與它們又毗鄰關系。通過手術顯微鏡測量下述解剖結構:乳突尖與環椎橫突尖、枕髁外側緣、 v _ 3上外側袢的距離;椎動脈v _ 3段在穿硬膜環、與第二頸神經前支交叉、環椎橫突孔上緣三處與中線的距離; v _ 3h在發出肌支處和穿硬膜天渾醫科大學碩士研究主學位論文環處的直徑; v3v在與第二頸神經前支交叉處和穿環椎橫突孔處的直徑。

Conclusion : in the craniotomy of the retrosigmoid approach , the lateral two hole should devised lateral and inferior to the asterion and fissure of the occipital - mastoid at the fundus of mastoid . it is a safe and fast drilling method N 、 t擴大乙狀竇后經內耳孔上入路顯微外科解剖學系列研究中文揚要枕乳縫乳突基底外下方為鉆孔點是安全、快速的方法。

Our study showed the following : mastoid process , transverse process of the atlas , and occipital condyle were important signs , superior and inferior suboccipital triangle is the important mark for distinguishing vertebral artery 研究顯示:乳突、環椎橫突和枕髁是術中重要的解剖學標志,上、下枕下三角是暴露椎動脈入顱前的一個重要解剖學標志。
