突发性聋的疗效与听力曲线图的关系

The relationship between the initial audiogram pattern and prognosis for cases with sudden deafness

目的：探讨突发性聋疗效与听力曲线图之间的关系。方法对328例（340耳）突发性聋病例进行回顾性分析，探讨其治疗前听力曲线图与预后的相关性。结果所有病例治疗前听力曲线图可以分为上升、山型、下降、凹陷、平坦和全聋型，统计各型与疗效的相关性。340耳总有效率为65%，各听力曲线图型疗效从高到低分别为上升型（92.1%）、山型（84.4%）、下降型（45.3%）、凹陷型（72.5%）、平坦型（80.6%）、全聋型（31.0%），疗效组间差异有统计学意义（χ2=104.67, P＜0.001）。结论突发性聋患者治疗前听力曲线图与疗效相关，以上升型和山型疗效最好，下降型、全聋型最差。

Objective To investigate the association of initial audiogram pattern with therapeutic effect for cases with sudden deafness. Method A retrospective study was carried out among 328 patients （340 ears） with sudden deafness, treated in our Hospital. Careful analysis was made to explore the correlation of initial audiogram pattern with therapeutic effect at last. Result The audiograms measured before treatment in this group of cases could be divided into six patterns, i.e. upward sloping pattern, peak pattern, downward sloping pattern, concave pattern, flat pattern and total deafness pattern, and their effective rates were （92.1%）, （84.4%）, （45.3%）, （72.5%）, （80.6%） and （31%） respectively, with very obviously statistical significance among them （χ2=104.67,P＆lt;0.001）, while the total effective rate was 65% for these 340 ears with sudden deafness. Conclusion The therapeutic effect is correlated with the initial audiogram pattern measured before treatment for patients with sudden deafness, with the best prognosis for those with audiograms in upward sloping or peak patterns and worst for ones with audiograms in downward sloping or total deafness.
