Objective tinnitus occurs as a result of muscular contraction or vascular pulsations. The literature is reviewed and we present two case reports of vascular objective tinnitus and its diagnostic and therapeutic modalities. One patient was treated with embolization alone; the other, with embolization and surgical ligation. Both patients achieved an improvement in sensorineural hearing thresholds in their affected ears; one patient experienced an improvement in speech reception threshold of 30 decibels. Measures useful to diagnosis and evaluation of therapy and reasons for the observed improved hearing thresholds are discussed.
客观性耳鸣是由肌肉收缩或血管搏动引起的。本文回顾了相关文献，并报告了两例血管性客观性耳鸣及其诊断和治疗方式的病例。一例患者仅接受了栓塞治疗；另一例则接受了栓塞和手术结扎治疗。两名患者患耳的感音神经性听力阈值均有所改善；其中一名患者的言语接受阈值提高了30分贝。文中讨论了对诊断和治疗评估有用的措施以及观察到听力阈值改善的原因。
