It is a common clinical impression that preservation of hearing is more often achieved when removing a meningioma than a similarly sized acoustic tumor. However, relatively few reports have focused on postoperative hearing results after meningioma removal, and detailed audiometric data are not commonly provided, particularly in the neurosurgical literature. During the past 16 years, 56 meningiomas affecting the temporal bone have been surgically removed at the House Ear Clinic. Hearing preservation was attempted in 16 (29%) of the 56 cases, and these were the focus of this study. The primary presenting symptom was otologic in 67% of these cases, including hearing loss as the primary symptom in 27%. Measurable postoperative hearing was present in 11 (92%) of 12 patients with postoperative audiograms available, and 8 (67%) of 12 patients had good hearing postoperatively. Hearing was preserved near the preoperative level (within 10 dB speech reception threshold and 15% speech discrimination) in 75% of cases.
临床上普遍认为，切除脑膜瘤时比切除同样大小的听神经瘤更常能实现听力保留。然而，相对较少的报告关注脑膜瘤切除术后的听力结果，并且通常不提供详细的听力测定数据，尤其是在神经外科文献中。在过去16年中，豪斯耳科诊所通过手术切除了56例累及颞骨的脑膜瘤。56例中有16例（29%）尝试保留听力，这些是本研究的重点。这些病例中67%的主要首发症状为耳科症状，其中27%以听力损失为主要症状。12例有术后听力图的患者中有11例（92%）术后有可测量的听力，12例患者中有8例（67%）术后听力良好。75%的病例听力保留在术前水平附近（言语接受阈值在10 dB以内且言语辨别率在15%以内）。
