低频型突聋伴耳闷胀感患者耳闷胀感特征及与突聋的关系

摘要

目的 探讨低频型突聋伴耳闷胀感患者耳闷胀感的临床特征、预后及与突聋的关系.方法 收集单侧低频型突聋伴耳闷胀感患者35例,不伴耳闷胀感患者32例,进行听力学及影像学检查,对伴耳闷胀感患者进行耳闷胀感的VAS量表评分及主观分级.比较两组患者耳声发射、听性脑干诱发电位改变;观察耳闷胀感预后,分析耳闷胀感与突聋的关系.结果 两组患者间耳声发射及脑干诱发电位结果 无显著差异(χ2=1.486,1.029;P>0.05).伴耳闷胀感患者耳闷胀感主观分级与听力下降程度呈正相关(r=0.344,P<0.05).伴耳闷胀感组经治疗后听力恢复总有效率32/35(91.4%)略高于不伴耳闷胀感组总有效率27/32(84.4%),差异无统计学意义(χ2=0.791,P>0.05).耳闷胀感恢复总有效率为31/35(88.6%),耳闷改善情况与听力下降改善情况存在相关性(χ2=9.891,P<0.05),pearson列联相关系数r=0.469,P<0.05.结论 低频型突聋伴耳闷胀感患者耳闷程度与听力下降程度相关,听力损失越严重,耳闷胀感的主观分级越重;耳闷胀感预后较好,与听力恢复情况相关;伴耳闷胀感患者听力恢复效果可能略好于不伴耳闷胀感患者,有待进一步观察.%Objective To report clinical features and prognosis of ear fullness sensation in and its relationship with low frequency sudden deafness. Methods Imaging and audiological data were obtained in 35 patients with unilater-al low frequency sudden hearing loss and ear fullness sensation and in 32 patients without ear fullness sensation. More-over, VAS scale scores and subjective grading of ear fullness sensation were acquired in patients with aural fullness. Changes of otoacoustic emissions and auditory evoked potentials were compared between the two groups to investigate prognostic values of ear fullness and analyze its relationship with hearing loss. Results There was no significant differ-ence between the two groups of patients with otoacoustic emissions and brainstem evoked potentials (χ2=1.486,1.029;P>0.05). Subjective grading of ear fullness was positively correlated with the degree of hearing loss(r=0.344,P<0.05). The total rate of hearing improvement following treatments in patients with ear fullness was 91.4% (32/35), slightly higher than that in patients with no ear fullness (84.4%, 27/32) (χ2=0.791,P>0.05). Ear fullness improved in 31 of the 35 patients (88.6%), and the improvement of ear fullness was related to improvement of hearing(χ2=9.891,P<0.05)(r=0.469, P<0.05). Conclusions The degree of hearing loss was positively correlated with the degree of ear fullness in patients with low frequency sudden deafness when they also have sensation of ear fullness. The prognosis of ear full-ness is better than hearing loss, which is also related to hearing recovery. Hearing recovery in patients with aural fullness appears to be slightly better than in patients without ear fullness,although further studies are needed.
