This study aimed to find out appropriate patients to evaluate the therapeutic effect of sudden deafness.
The study design was a retrospective case review.
The study was performed at a university hospital.
A series of 443 patients with idiopathic sudden sensorineural hearing loss who visited the authors within 1 week from the onset participated.
Relationship between interval from the onset and treatment prognosis was investigated.
The significant difference in prognosis related to the days from the onset to the initial visit was noted only in the patients with the initial hearing level from 50-65 dB. The prognosis of the patients who visited the authors on the next day from the onset was excellent. Whereas, in the patients with initial hearing level worse than 70 dB, no significant difference in prognosis was noted among the days of visit.
The patients with the initial hearing level worse than 70 dB and who visited the authors within 8 days from the onset were appropriate for candidates in evaluating the therapeutic effect of sudden deafness.
本研究旨在找出适合评估突发性聋治疗效果的患者。
本研究设计为回顾性病例分析。
本研究在一所大学医院进行。
443例特发性突发性感音神经性听力损失患者在发病1周内就诊并参与研究。
研究发病间隔与治疗预后之间的关系。
仅在初始听力水平为50 - 65分贝的患者中，观察到从发病到初次就诊天数与预后存在显著差异。发病次日就诊的患者预后良好。然而，初始听力水平低于70分贝的患者，就诊天数之间的预后无显著差异。
初始听力水平低于70分贝且在发病8天内就诊的患者适合作为评估突发性聋治疗效果的候选对象。
