突發性耳聾(idiopathic sudden sensorineural hearing loss)指的是3天之内，連續3個聲音頻率，大於 30分貝感音神經性聽力喪失。突發性耳聾的治療主要有3大類型：口服或靜脈注射類固醇、耳内注射類 固醇與高壓氧治療。本病例報告為2017年一至五月連續八位突發性耳聾的患者，在本院接受耳内注射類 固醇合併高壓氧治療，顯示四位在發病兩週内就接受合併治療的病人聽力可恢復81-100°% ;另四位超過 兩週以上再接受合併治療病人聽力的改善只有0-60°%，三位有聽力改善皆在低音頻。其中有一例右耳五 年前失聰患者，再發生左耳突發性耳聾，病發後五天後經左耳耳内注射類固醇合併10次高壓氧治療後， 左耳聽力恢復正常，右耳聽力也有44%的改善。本案例報告顯示耳内注射類固醇合併高壓氧治療對突發 性耳聾值得進一步的研究。

The criteria of Idiopathic sudden sensorineural hearing loss (ISSNHL) is a decrease of hearing larger than 30 decibels (dB), affecting at least 3 consecutive frequencies, occurring within a 72-hour period. The current treatment options include oral or systemic steroid, intratympanic steroid injection (ITS), and hyperbaric oxygen therapy (HBOT). We reported 8 consecutive cases of ISSNHL treated with concurrent HBOT and ITS from January to May 2017. Four cases treated within 2 weeks after the onset of ISSNHL had 81-100% gain of hearing in all frequencies of audiogram. The other four cases treated 2 weeks after the onset of ISSNHL had 0-60% gain in low frequencies of audiogram in three cases. A case with right hearing loss 5 years ago received concurrent left ITS and HBOT 5 days after the onset of left ISSNHL. After 10 sessions of HBOT there were complete recovery of hearing of left ear and 44% gain in low frequencies of audiogram of right ear. The findings of the present study encourage further research on the treatment of ISNHL with concurrent use of HBOT and ITS.
