BACKGROUND
The surgical approach of acoustic neuroma includes translabyrinthine, transcranial fossa, suboccipital retrosigmoid sinus, and presigmoid retrolabyrinthine approach. Aims/Objective: To provide the anatomical basis for the surgical selection of presigmoid retrolabyrinthine approach by measuring the anatomical parameters of retrolabyrinthine space of the petrous bone by high-resolution CT.
MATERIAL AND METHODS
A retrospective study of 208 high-resolution CT (HRCT) images of 104 patients examined in our hospital were analyzed retrospectively. Forty-nine males and 55 females were included in this study. Lines were drawn on the HRCT to measure the morphological data for pre-operational assessment.
RESULT
Morphological data were retracted from HRCT, for preoperational assessment.
CONCLUSION AND SIGNIFICANCE
Using the standard postprocessing images of temporal bone HRCT can predict the size of the retrolabyrinthine space and the degree of exposure to the inner auditory canal, providing an important anatomical index for the choice of presigmoid retrolabyrinthine approach.
背景
听神经瘤的手术入路包括经迷路入路、经颅中窝入路、枕下乙状窦后入路和乙状窦前迷路后入路。目的：通过高分辨率CT测量岩骨迷路后间隙的解剖参数，为乙状窦前迷路后入路的手术选择提供解剖学依据。
材料与方法
回顾性分析我院104例患者的208幅高分辨率CT（HRCT）图像。本研究纳入49例男性和55例女性。在HRCT上画线以测量形态学数据用于术前评估。
结果
从HRCT中提取形态学数据用于术前评估。
结论与意义
利用颞骨HRCT的标准后处理图像可预测迷路后间隙的大小及内耳道的暴露程度，为乙状窦前迷路后入路的选择提供重要的解剖学指标。
