The middle cranial fossa surgical approach has been used for the removal of acoustic neuromas in 43 patients at the University of Iowa since 1974. Hearing was maintained in 50% of patients with tumors 1.5 cm or less outside the porus acusticus. Postoperative hearing, facial nerve function, and complications were similar to reports using the suboccipital or retrosigmoid approach to preserve hearing for this size tumor. The character of the tumor appears to dictate the postoperative outcome rather than the surgical approach.
自1974年以来，爱荷华大学对43例患者采用中颅窝手术入路切除听神经瘤。对于内听道外肿瘤直径在1.5厘米或更小的患者，50%的患者听力得以保留。术后听力、面神经功能及并发症与采用枕下或乙状窦后入路保留该大小肿瘤听力的报告相似。肿瘤的特征似乎决定了术后结果，而非手术入路。
