Abstract

Objective: To investigate the clinical features and prognosis in patients with idiopathic sudden sensorineural hearing loss (ISSNHL) with blood-labyrinth barrier breakdown (BLB-B). Methods: Clinical data of patients with unilateral ISSNHL hospitalized from December 2017 to December 2018 were retrospectively analyzed. According to the results of 3D-FLAIR MRI and enhanced MRI scanning, these patients were divided into two groups, i.e., normal and abnormal inner ear groups. The patients in abnormal inner ear group were further divided into two subgroups: BLB-B and BLB-B with exudation. The differences and correlations among the groups in clinical characteristics, in terms of gender, age, deafness side, basic diseases, dizziness/vertigo, vestibular function, hearing loss degree, as well as classification of hearing curve, and prognosis were analyzed by statistical software SPSS 23.0. Results: Data were collected from 150 cases, in which 68 were male and 82 were female, aged (46.2±14.6) years, including 67 cases with normal inner ears and 83 cases with abnormal inner ears (13 cases with BLB-B; 70 cases with BLB-B and exudation). The dizziness/vertigo incidence, side ratio, hearing loss degree, classification of hearing curve, vestibular dysfunction (vestibular double temperature test, HIT and VAT) and therapeutic effect were different between normal and abnormal inner ear groups (P<0.05). The dizziness/vertigo incidence, side ratio, hearing loss degree, classification of hearing curve, vestibular dysfunction (vestibular double temperature test, o/cVEMP, HIT and VAT) and therapeutic effect were different among normal inner ear, BLB-B and BLB-B with exudation groups (P<0.05). Pairwise comparison between groups revealed that vestibular dysfunction (vestibular double temperature test, o/cVEMP, HIT and VAT) and therapeutic effect were different between normal inner ear and BLB-B groups (P<0.05); The dizziness/vertigo incidence, side ratio, hearing loss degree, classification of hearing curve, vestibular dysfunction (vestibular double temperature test, o/cVEMP, HIT and VAT) and therapeutic effect were different between normal inner ear and BLB-B with exudation groups (P<0.05). There was no significant different between BLB-B and BLB-B with exudation groups. Conclusion: BLB-B displayed by 3D-FLAIR MRI manifestation in ISSNHL patients indicates more serious cochlear and vestibular dysfunction, and worse therapeutic effect.

目的: 探讨血迷路屏障破坏的特发性突发性聋(突聋)患者的临床特征及预后。 方法: 回顾性分析2017年12月至2018年12月在山东省耳鼻喉医院耳内科住院治疗的成人单侧突聋患者的临床资料,依据内耳3D-FLAIR MRI平扫和强化扫描结果分为内耳正常组和内耳异常组,内耳异常组进一步分为单纯血迷路屏障破坏(blood-labyrinth barrier breakdown,BLB-B)组和BLB-B伴渗出组,应用SPSS 23.0统计软件分析组间性别、年龄、侧别、基础疾病、头晕/眩晕、前庭功能、听力损失程度、听力分型和疗效的差异及相关性。 结果: 共收集资料完整的特发性突聋患者150例,其中男68例,女82例,年龄(46.2±14.6)岁;内耳正常组67例,内耳异常组83例(BLB-B组13例,BLB-B伴渗出组70例)。内耳正常组和异常组间比较:头晕/眩晕伴发率、耳聋侧别、听力损失程度、听力分型、前庭功能[冷热试验、头脉冲试验(HIT)和前庭自旋转试验(VAT)]异常率、疗效分布等差异均具有统计学意义(P值均<0.05)。内耳正常组、BLB-B组、BLB-B伴渗出组三组间比较,头晕/眩晕伴发率、耳聋侧别、听力损失程度、听力分型、前庭功能[冷热试验、肌源性前庭诱发电位(VEMP)、HIT、VAT]异常率、疗效分布差异均具有统计学意义(P值均<0.05);组间两两比较,BLB-B组与正常组间,前庭功能(冷热试验、VEMP、HIT、VAT)异常率和疗效分布差异具有统计学意义(P值均<0.05);BLB-B伴渗出组与正常组间,头晕/眩晕伴发率、耳聋侧别、听力损失程度、听力分型、前庭功能(冷热实验、HIT、VAT)异常率、疗效分布差异均具有统计学意义(P值均<0.05);BLB-B组与BLB-B伴渗出组间,各指标间差异无统计学意义(P值均>0.05)。 结论: 内耳3D-FLAIR MRI增强扫描显示血迷路屏障破坏的突发性聋患者,耳蜗和前庭功能受损重,预后差。.
