Idiopathic facial nerve paresis still remains a challenge for laryngologists and neurologists. The etiology of idiopathic peripheral facial nerve paresis has not been explained so far. There is a group of patients that complain about coexisting hearing abnormalities.
Analysis of audiological abnormalities in patients with idiopathic peripheral facial nerve paresis on the basis of pure tone audiometry and auditory brainstem responses.
The retrospective analysis of 35 patients, aged under 40 years, with idiopathic peripheral facial nerve paresis hospitalised in Department of Otolaryngology of Warsaw Medical University-Poland (2004-2009). Control group consisted of age-matched, 23 healthy subjects. Each patient underwent audiometric evaluation that included pure tone audiometry and auditory brainstem responses. Statistical analysis was performed with Student's t-test.
In the analysed group of 35 patients (17 male + 18 female), age ranged 13-40 years (mean 26.7 +/- 7.1) significantly prolonged latencies of wave III and V and III-V and I-V intervals in comparison with control group where observed (p < 0.05). We found also that 48.6% patients with idiopathic peripheral facial nerve paresis had high-frequency hearing loss.
The auditory brainstem responses in this study showed an association between retrocochlear pathology of the auditory system and idiopathic peripheral facial nerve paresis. Further investigations are necessary to estimate the etiopathology of these coexisting abnormalities.
特发性面神经麻痹仍然是耳鼻喉科医生和神经科医生面临的一项挑战。迄今为止，特发性周围性面神经麻痹的病因尚未得到解释。有一组患者抱怨存在听力异常。
基于纯音听力测定和听觉脑干反应，分析特发性周围性面神经麻痹患者的听力学异常情况。
对35例年龄在40岁以下、因特发性周围性面神经麻痹入住波兰华沙医科大学耳鼻喉科的患者（2004 - 2009年）进行回顾性分析。对照组由23名年龄匹配的健康受试者组成。每位患者均接受了听力评估，包括纯音听力测定和听觉脑干反应。采用学生t检验进行统计学分析。
在分析的35例患者组（17例男性 + 18例女性）中，年龄范围为13 - 40岁（平均26.7 +/- 7.1），与对照组相比，观察到波III和波V以及III - V和I - V间期的潜伏期显著延长（p < 0.05）。我们还发现，48.6%的特发性周围性面神经麻痹患者存在高频听力损失。
本研究中的听觉脑干反应显示听觉系统的蜗后病变与特发性周围性面神经麻痹之间存在关联。需要进一步研究以评估这些共存异常的病因病理。
