To investigate the efficacy of intratympanic dexamethasone injection (IDI) for 23 patients with intractable sudden sensorineural hearing loss (SSNHL).
Dexamethasone (5 g/ml) was injected into the middle ear. The injection was repeated once two days and had a total of 4 doses (10 mg).
The 23 patients were followed up for one month. Eight of 23 patients (34.8%) demonstrated a 17 to approximately 54 dB improvement in PTA and 15 of 23 (65.2%) had no response.
IDI is a simple and effective treatment for SSNHL patient who had not responded to conventional therapy, although hearing was rarely improved to normal levels.
探讨鼓室内注射地塞米松（IDI）治疗23例难治性突发性感音神经性听力损失（SSNHL）患者的疗效。
将地塞米松（5mg/ml）注入中耳。每两天重复注射一次，共4剂（10mg）。
对23例患者进行了1个月的随访。23例患者中有8例（34.8%）纯音听阈平均提高了17至约54dB，23例中有15例（65.2%）无反应。
IDI是治疗对传统疗法无反应的SSNHL患者的一种简单有效的方法，尽管听力很少能恢复到正常水平。
