In summary, the patient with a unilateral sensorineural type hearing loss, unilateral tinnitus, or dysequilibrium may have a tumor in the posterior fossa. This is diagnosed by the history, ear nose, throat and otoneurological examination, the audiological studies, electronystagmography, radiological tests using the Compere unit, the CT Scan, and when indicated the posterior fossa myelogram. The list of causes for these symptoms other than tumefaction is large and there are a significant number of cases that remain "cause undetermined." The latter requires diligent follow-up and even consultation elsewhere.
总之，患有单侧感音神经性听力损失、单侧耳鸣或平衡失调的患者可能在后颅窝长有肿瘤。这可通过病史、耳鼻喉及耳神经学检查、听力学研究、眼震电图、使用Com pere装置的放射学检查、CT扫描以及必要时的后颅窝脊髓造影来诊断。除肿瘤外，这些症状的病因众多，且有相当数量的病例仍“病因不明”。后者需要进行密切随访，甚至到其他地方咨询。
