In many cases of acoustic tumor the hearing loss is gradually progressive, but some cases of acoustic tumor show a sudden onset of hearing loss. In this paper we report two interesting cases of acoustic tumors which were diagnosed as sudden deafness at the first examination. Being treated with steroid hormones, their hearing was partially recovered. But the hearing loss recurred in both cases. At the second examination, CT showed the cerebellopontine angle tumors. So it was emphasized that careful questioning as well as the caloric test and the auditory brainstem response (ABR) was important. If one of these tests shows abnormality, the patient should be examined by the CT scan. The same may be said of patients who show recovery due to steroid hormone therapy.
在许多听神经瘤病例中，听力损失是逐渐进展的，但有些听神经瘤病例表现为听力突然丧失。在本文中，我们报告了两例有趣的听神经瘤病例，这两例在首次检查时被诊断为突发性耳聋。经类固醇激素治疗后，他们的听力部分恢复。但两例听力损失均复发。第二次检查时，CT显示桥小脑角肿瘤。因此强调，仔细询问病史以及进行冷热试验和听性脑干反应（ABR）很重要。如果这些检查中有一项显示异常，就应该对患者进行CT扫描。对于因类固醇激素治疗而听力恢复的患者也是如此。
