The authors present two cases in which the palsies of the IX, X, XI and XII nerves heralded the presence of a neurilemoma within the jugular foramen. Temporary bone polytomography, retrograde jugular venography, and pantopaque posterior fossa myelography allowed the nature and extent of the tumor to be predicted accurately prior to the operation. The tumors were completely removed using a transmastoid-extended facial recess approach without labyrinthectomy, supplemented in one case by exploration of the upper cervical portion of the internal jugular vein. This technique has avoided the complications which attend removal by way of the posterior fossa. We feel that transmastoid removal merits more extensive clinical trial.
作者报告了两例病例，其中第IX、X、XI和XII神经麻痹预示着颈静脉孔内存在神经鞘瘤。术前通过颞骨断层扫描、逆行颈静脉造影和碘苯酯后颅窝脊髓造影能够准确预测肿瘤的性质和范围。采用经乳突-扩大的面神经隐窝入路，在不进行迷路切除的情况下完全切除肿瘤，其中1例还探查了颈内静脉的上颈部。该技术避免了经后颅窝手术切除所带来的并发症。我们认为经乳突切除值得更广泛的临床试验。
