[The effects of postauricular injection of methylprednisolone on medium-high frequency sudden hearing loss]
Abstract:
Objective:To study the effects of postauricular injection of methylprednisolone on medium-high frequency sudden hearing loss.Method:The data of 45 patients with invalid treatment who were diagnosed as medium-high frequency sudden hearing loss were retrospectively studied. They were divided into postauricular injection group and non-postauricular injection group. The treatment efficiency and hearing improvement at each frequency were compared between the two groups.Result:The improvements of hearing threshold in the non-postauricular injection group were(6.30±5.00)dB HL,(3.80±5.52)dB HL,(5.35±5.50)dB HL,(15.60±11.84)dB HL,(19.60±13.46)dB HL,(15.40±12.90)dB HL at 250, 500, 1000, 2000, 4000 and 8000Hz, respectively. The hearing improvements of the postauricular injection group were (5.35±6.22)dB HL,(2.50±3.00)dB HL,(4.65±6.60)dB HL,(23.75±10.75)dB HL,(25.75±11.73)dB HL,(30.50±14.50)dB HL at 250, 500,1000,2000,4000 and 8000Hz, respectively. There were significant differences between the two groups in hearing improvements at 2000-8000Hz. The treatment effective rates were 44% and 80% for the non-postauricular injection group and postauricular injection group respectively, which showed a significant difference(χ²=8.385P<0.05).Conclusion:Postauricular injection of methylprednisolone as a remedy treatment is safe and effective for sudden hearing loss in middle and high frequency.
