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於星點外下方，橫斷面上，平均距離為10 -
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
