Retrospective study aiming at evaluating the interference of associate diseases in the evolution and prognosis of idiopathic sudden sensorineural hearing loss.
Case-Control Study. Thirty-five patients with idiopathic sudden sensorineural hearing loss were divided in two groups, one of them with associate diseases (hypertension, diabetes mellitus and dyslipidemias), and another one without co-occurrence of such diseases. The groups were evaluated regarding: age, gender, associate diseases, presence of tinnitus, dizziness and ear fullness sensation, presence of cerebral microangiopathy observed in magnetic resonance imaging, ophthalmoscopic findings, treatment onset, improvements in audiometric findings and at speech discrimination tests. Statistical analysis of data was performed.
The associate disease group showed higher ages, cerebral microangiopathy observed in magnetic resonance imaging and later improvement in speech discrimination tests, being this difference statistically significant.
Idiopathic sudden sensorineural hearing loss co-occurring with hypertension, diabetes mellitus or dyslipidemias, in older patients, is associated with a higher prevalence of cerebral microangiopathy, revealed by magnetic resonance imaging, and associated with a slower hearing recovering, showed by later improvements in speech discrimination tests.
回顾性研究旨在评估伴发疾病对特发性突发性聋的演变和预后的影响。
病例对照研究。35 例特发性突发性聋患者分为两组，一组伴有伴发疾病（高血压、糖尿病和血脂异常），另一组无伴发疾病。评估两组患者的年龄、性别、伴发疾病、耳鸣、头晕和耳闷感、磁共振成像观察到的脑微血管病、眼底检查、治疗开始时间、听力和言语辨别测试结果的改善情况。对数据进行统计学分析。
伴发疾病组的年龄较大，磁共振成像观察到脑微血管病较多，言语辨别测试结果改善较晚，差异有统计学意义。
在年龄较大的患者中，特发性突发性聋伴发高血压、糖尿病或血脂异常与磁共振成像显示的脑微血管病发生率较高相关，并且与言语辨别测试结果改善较晚导致的听力恢复较慢相关。
