An anatomical study was performed in order to obtain help for orientation regarding the retrosigmoid approach and its osteoclastic craniotomy. The insertions of the sternocleidomastoid, the splenius capitis, the longissimus capitis and the obliquus capitis superior muscles were measured. The relationships of the insertions to different landmarks were also ascertained (FHP, suprameatal spine). In 37 specimens 6 burrholes with a standardized relationship to the Frankfurt Horizontal Plane (FHP) and the external auditory meatus, were performed. Due to the results of the relationship between burrholes and the sigmoid and transverse sinuses it is possible to give an optimal position for the initial burrhole of the osteoclastic craniotomy. A burrhole performed according to the result of this study has a relatively small risk concerning iatrogenic bleeding from the sigmoid and transverse sinuses caused by the burrhead of the drill.
为了在乙状窦后入路及其骨质切除术开颅方面获得定位帮助，进行了一项解剖学研究。测量了胸锁乳突肌、头夹肌、头最长肌和头上斜肌的附着点。还确定了附着点与不同标志（FHP、外耳道上棘）的关系。在37个标本上，钻出了6个与法兰克福水平面（FHP）和外耳道具有标准化关系的钻孔。根据钻孔与乙状窦和横窦之间关系的结果，可以给出骨质切除术开颅初始钻孔的最佳位置。根据本研究结果钻出的钻孔，因钻头导致乙状窦和横窦医源性出血的风险相对较小。
