查询词典 clival

Drilling of the jugular tuberculum is the key step for access to the central clival depression. Partial mastoidectomy can result in a significant increase in surgical freedom, but only a modest increase in the exposure of the central clival depression. Removal of total condyle and resection of the lateral mass of C1 could not increase the surgical freedom and exposure of the central clival depression.

磨除颈静脉结节为经FLA入路显露斜坡中央凹陷区的关键步骤；部分乳突切除可进一步改善操作空间，但未能显著增加斜坡中央凹陷区的显露；全切枕髁和侧块不能显著增加斜坡中央凹陷区的显露和操作空间。

Methods Central point at the central clival depression was marked with the help of CT and stereotactic apparatus in 20 formalin-fixed cadaveric heads. The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.
