To study whether secretory otitis media causes sensorineural deafness or not, especially in stubborn cases.
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.
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 4 kHz.
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.
研究分泌性中耳炎是否会导致感音神经性耳聋，尤其是在顽固病例中。
对164例分泌性中耳炎患者施加0.5kHz、1kHz、2kHz、4kHz的骨导（BC）刺激，并计算其骨导听力损失。作为对照，还记录了66例单侧耳聋患者对侧耳的骨导阈值。
164例患者中有94例（57.3%）骨导阈值升高。双侧耳聋组和单侧耳聋组之间无统计学显著差异。所有患者在相同频率下骨导听力损失相似，但在不同频率下骨导听力损失不同，且最严重的损失发生在4kHz。
分泌性中耳炎导致感音神经性耳聋的发生率高于预期。分泌性中耳炎单侧耳聋和双侧耳聋患者的听力损失频率和强度无差异。所有耳朵在不同频率下听力损失不同，但最严重的听力损失发生在高频，且有向言语频率扩散的趋势。
