摘要
目的探讨分泌性中耳炎(secretoryotitismedia,SOM)对扩展高频听力的影响。方法对31例(32耳)SOM患者治疗前和治疗2周后行纯音测听及扩展高频测听,骨导频率范围为250Hz～8kHz,气导频率范围250Hz～20kHz,并与16例(32耳)健康对照组比较。结果治疗前有31.3%SOM患者平均骨导阈值>25dB,平均骨导阈值与对照组相比有显著性差异(P<0.01),骨导阈值在2、4kHz处差异明显(P<0.01),治疗后平均骨导阈值与对照组相比无显著差异(P>0.05)。在扩展高频段,治疗前、后所有频率气导阈值均与对照组有明显差异(P<0.01),且有随着频率增高,治疗后气导改善逐渐减少的趋势。结论SOM患者导致的感音神经性聋由低频到扩展高频逐渐加重,治疗后低频区听力恢复较快,扩展高频区改善不明显。
Objective To investigate the auditory function of extended high frequency in patients with secretory otitis media（SOM）. Methods The 250 Hz - 8 kHz BC stimuli and 250 Hz - 20 kHz AC stimuli were administered to 31 patients（32 ears） with SOM and 16 controls（32 ears）. Results The average BC threshold of 10 （31.3 % ） ears was over 25 dB pretherapy. There was statistically significant difference between SOM and controls（ P 〈 0.01 ）. The BC heating loss was serious in 2 and 4 kHz. Through a two weeks therapy, the average BC threshold had no statistically significant difference between SOM and controls（ P 〉 0. 05） ,but the AC threshold in all extended high frequencies still had statistically significant difference（ P 〈 0.01 ）. Conclusion SNHL caused by SOM has a tendency to be more serious when the frequency raised. The heating loss in extended high frequencies recoveres more slowly than in conventional frequencies. We must pay enough attention to a possible development of SNHL during the course of SOM.
