The middle cranial fossa (MCF) approach for acoustic neuromas has been criticized for limited exposure, anatomic surgical difficulty, and increased risk to facial nerve and temporal lobe. From 1986 to the present, 49 patients' acoustic neuromas were removed via the MCF approach. Hearing was preserved or improved in 69% of patients regardless of preoperative hearing levels, and facial nerve function was Grade II or better in 94%. Both results demonstrate improvement from our report 8 years ago. In addition, all patients are without recurrence. Our results continue to demonstrate the surgical advantages of the MCF approach and that, in experienced hands, it is as efficacious as other hearing preservation approaches.
经中颅窝（MCF）入路切除听神经瘤一直受到批评，原因是暴露有限、解剖手术难度大以及面神经和颞叶风险增加。从1986年至今，49例患者的听神经瘤通过MCF入路切除。无论术前听力水平如何，69%的患者听力得以保留或改善，94%的患者面神经功能为二级或更好。这两个结果均显示较我们8年前的报告有所改善。此外，所有患者均无复发。我们的结果继续证明了MCF入路的手术优势，并且在经验丰富的医生手中，它与其他听力保留入路一样有效。
