To investigate the effects of insomnia on tinnitus severity and to determine how this relationship may evolve with the passage of time.
Questionnaires were mailed to patients before their initial appointment at the Oregon Health Sciences University Tinnitus Clinic between 1994 and 1997. These questionnaires requested information pertaining to insomnia, tinnitus severity, and loudness. During their initial appointment, patients received counseling, education, and reassurance about tinnitus; audiometric and tinnitus evaluations; and treatment recommendations. Follow-up questionnaires were mailed to 350 patients 1 to 4 years (mean = 2.3 yr) after their initial appointment at the clinic.
One hundred seventy-four patients (130 men, 44 women; mean age 55.9 yr) returned follow-up questionnaires. Although many of these patients improved in both sleep interference and tinnitus severity, a significant number (43) reported on the follow-up questionnaire that they continued to have difficulty sleeping. Reported loudness and severity of tinnitus were significantly greater for this group than for groups of patients who reported that they never or only sometimes have difficulty sleeping. The relationship between sleep disturbance and tinnitus severity became more pronounced with the passage of time.
Insomnia is associated with greater perceived loudness and severity of tinnitus. These findings underscore the importance of identification and successful treatment of insomnia for patients with tinnitus.
研究失眠对耳鸣严重程度的影响，并确定这种关系如何随时间演变。
1994年至1997年间，在患者首次预约前往俄勒冈健康科学大学耳鸣诊所就诊前，向其邮寄问卷。这些问卷要求提供有关失眠、耳鸣严重程度和响度的信息。在首次就诊期间，患者接受了关于耳鸣的咨询、教育和安抚；听力测定和耳鸣评估；以及治疗建议。在患者首次就诊诊所1至4年（平均2.3年）后，向350名患者邮寄了随访问卷。
174名患者（130名男性，44名女性；平均年龄55.9岁）返回了随访问卷。尽管这些患者中的许多人在睡眠干扰和耳鸣严重程度方面都有所改善，但仍有相当数量（43名）的患者在随访问卷中报告他们仍然存在睡眠困难。与那些报告从未或只是偶尔有睡眠困难的患者组相比，该组报告的耳鸣响度和严重程度明显更高。随着时间的推移，睡眠障碍与耳鸣严重程度之间的关系变得更加明显。
失眠与更高的耳鸣响度和严重程度感知相关。这些发现强调了识别并成功治疗耳鸣患者失眠的重要性。
