摘要
目的 证实分泌性中耳炎可导致感音神经性聋 ,为临床干预分泌性中耳炎 ,尤其是顽固的分泌性中耳炎提供依据。方法 115例 (16 4耳 )分泌性中耳炎患者治愈后或未愈患者病程中复查的纯音测听检查结果 ,记录 0 .5、1、2、4kHz频率骨导听阈 ,计算骨导听力损失dB数。分为单侧组 6 6例 ,双侧组 49例 ,将 6 6例单耳患者的健耳作为对照组。结果 在 16 4耳中 ,出现骨导听阈提高的共94耳 (5 7.3% )。双侧组与单侧组骨导听力损失程度差异均无显著性 (P >0 .0 5 ) ;单侧组和双侧组患耳在同一频率的骨导听力损失程度相似 ,且平均的骨导听力损失程度也相似 ;不同频率之间的骨导听力损失不同 ,4kHz的骨导听力损失为最大。结论 半数以上分泌性中耳炎可以导致感音神经性聋。在不同频率间的骨导听力损失不同 ,以高频损失为主 。
Objective To study whether secretory otitis media causes sensorineural deafness or not, especially in stubborn cases. Methods The 0.5 kHz, 1 kHz, 2 kHz, 4 kHz BC stimuli were administered to 164 patients with secretory otitis media, and their BC loss calculated. As a control, BC threshold was also recorded in the contralateral ear of 66 unilaterally deaf patients. Results BC threshold was raised in 94 out of 164 patients (57.3%). There was no statistically significant difference between bilaterally and unilaterally deaf groups. All patients had similar BC hearing loss in the same frequency, but had different BC hearing loss in different frequencies and the most serious loss was in 4kHz. Conclusion The rate of sensorineural deafness caused by secretory otitis media is higher than expected. Frequency and intensity of hearing loss between unilaterally and bilaterally deaf patients with secretory otitis media were no different. All ears had different hearing loss in different frequencies, but the most serious hearing loss was in high frequency and it had the tendency to spread to the speech frequency.
