A series of 40 patients with acoustic neuromas were operated on using the suboccipital or the translabyrinthine approach. Some patients were operated on using both routes. The series extends back to 1977 and contain predominantly large tumours. There was no mortality in the translabyrinthine series of 14 patients. In the suboccipitally treated series of 29 patient, 3 were previously treated using translabyrinthine approach. In this series there was one death directly due to sequelae of neuroma extirpation and in another, additional causes were present. Preoperative facial pareses were frequent. There were several additional pareses in the translabyrinthine series and also several additional in the suboccipital series. Facial pareses were operated on by a plastic surgeon and they did not markedly detract from working capacity. Only 2 patients in the total series had small tumours and useful preoperative hearing. Cochlear function was preserved in them.
对40例听神经瘤患者采用枕下或经迷路入路进行手术。部分患者采用了两种入路进行手术。该系列病例可追溯至1977年，主要为大型肿瘤。14例经迷路入路手术的患者无死亡病例。在29例采用枕下入路治疗的患者中，有3例先前接受过经迷路入路手术。在该系列中，有1例直接死于听神经瘤切除术后遗症，另1例存在其他病因。术前面神经麻痹很常见。经迷路入路系列中有几例额外的麻痹病例，枕下入路系列中也有几例。面神经麻痹由整形外科医生进行手术治疗，这些麻痹并未明显影响工作能力。整个系列中只有2例患者肿瘤较小且术前听力良好，保留了他们的耳蜗功能。
