For exposure of the cerebello-pontine angle by an enlarged middle-fossa approach without destruction of the inner ear, bone removal anterior and posterior to the internal auditory meatus (c.a.i.) can be performed with orientation at landmarks. Based on the experience of more than 300 interventions and documented by a series of 10 temporal bone micro-dissections, rules have been established for reliable localization of the following structures: geniculate ganglion, Fallopian canal, vertical crest at the fundus of the c.a.i., basal coil of the cochlea, and ampulla of the superior semicircular canal. The surgical technique has enabled the authors to remove acoustic neurinomas of up to 3.5 cm with preservation of hearing in 51%.
采用扩大中颅窝入路暴露桥小脑角而不破坏内耳时，可在标志定位的基础上对内耳道（c.a.i.）前后的骨质进行切除。基于300多次手术的经验并经一系列10次颞骨显微解剖记录，已制定出可靠定位以下结构的规则：膝状神经节、面神经管、内耳道底部的垂直嵴、耳蜗底圈和上半规管壶腹。该手术技术使作者能够切除直径达3.5 cm的听神经瘤，51%的患者听力得以保留。
