Fifty-one consecutive patients undergoing hearing preservation surgery for acoustic neuromas were evaluated with regard to tinnitus and level of hearing. In 25 patients, hearing was not preserved. In this group, postoperative tinnitus was present in 8 of 13 patients who noted this symptom preoperatively. Four of the remaining 12 patients developed tinnitus following surgery. In 26 patients, useful hearing was preserved (speech reception threshold < 50 dB, speech discrimination score > 60%). Although 10 patients in this group complained of tinnitus preoperatively, only 4 patients noted it following surgery. None of the 16 remaining patients in this group developed tinnitus postoperatively. Overall, only 50% (12/23) of patients who had tinnitus preoperatively complained of it postoperatively, and only 8% (4/51) developed tinnitus as a result of surgery. Our results show that new-onset tinnitus is uncommon following hearing preservation surgery for acoustic neuroma and that it can be reduced or eliminated following surgery, especially if useful hearing is preserved.
对51例连续接受听神经瘤听力保留手术的患者进行了耳鸣和听力水平评估。25例患者听力未保留。在该组中，13例术前有耳鸣症状的患者中，8例术后仍有耳鸣。其余12例患者中有4例术后出现耳鸣。26例患者有用听力得以保留（言语接受阈<50dB，言语辨别得分>60%）。尽管该组中有10例患者术前抱怨有耳鸣，但术后只有4例患者提及。该组其余16例患者术后均未出现耳鸣。总体而言，术前有耳鸣的患者中只有50%（12/23）术后仍抱怨有耳鸣，且只有8%（4/51）的患者因手术出现耳鸣。我们的结果表明，听神经瘤听力保留手术后新发耳鸣并不常见，且术后耳鸣可减轻或消除，尤其是在有用听力得以保留的情况下。
