骨迷路

结论本研究结果为骨迷路结构研究增添了新的内容，为临床内耳手术的开展提供解剖学基础和参考数据。

Conclusions The results is not only give some new contents of the bony labyrinth but also provide anatomic criteria for operations of inner ear .

组合多种三维可视化模型能够显示岩骨段颈内动脉与邻近的骨迷路、内听道等结构的空间位置关系。

Spatial relationships between petrous internal carotid artery and adjacent structures , including bony labyrinthine , internal meatus , and other landmarks were satisfactorily displayed via a combination of various modeling techniques of three-dimensional visualization .

方法模拟幕上下联合经岩骨入路的手术操作，在手术显微镜下对10具（20侧）福尔马林固定的成人带颈头颅标本进行解剖，并观测骨迷路及其与重要结构间的解剖关系。

Methods Twenty sides of 10 adult cadaver heads fixed in formalin were used , the anatomy of the bony labyrinth and the relationship of the correlative structures were observed and measured , and meanwhile the actual surgical procedure was mimicked under the surgical microscope .
