Clinical trial of methylprednisolone sodium succinate combined with hyperbaric oxygen in nerve deafness patients
Objective To compare the clinical curative effect of retroauricular and tympanic injection of methylprednisolone sodium succinate combined with hyperbaric oxygen in nerve deafness.Methods A retrospective analysis was performed on the case data with nerve deafness.According to cohort method,they were divided into retroauricular injection group(retroauricular injection of 40 mg methylprednisolone sodium succinate+hyperbaric oxygen therapy)and tympanic injection group(tympanic injection of 40 mg methylprednisolone sodium succinate+hyperbaric oxygen therapy).Both groups were treated for 7 times(once every other day).The curative effect,pure tone hearing threshold,oxidative stress and inflammatory response indexes were compared between the two groups,and adverse reactions were statistically analyzed.Results There were 56 cases in retroauricular injection group and 60 cases in tympanic injection group.There was no significant difference in total response rate between retroauricular injection group and tympanic injection group(92.86％vs 88.33％,P＞0.05).After treatment,average pure tone hearing thresholds in retroauricular injection group and tympanic injection group were(38.49±5.71)and(40.35±6.23)dB;high-frequency hearing thresholds were(61.36±6.52)and(63.42±7.09)dB;low-frequency hearing thresholds were(59.72±6.85)and(60.81±7.26)dB;levels of superoxide dismutase(SOD)were(112.38±10.72)and(110.43±10.29)U·mL-1;levels of lipid peroxide(LPO)were(4.69±1.08)and(5.03±1.12)nmol·mL-1;endothelin(ET)levels were(2.11±0.76)and(2.34±0.81)ng·L-1;interleukin-6(IL-6)levels were(31.79±4.27)and(33.18±4.98)pg·mL-1;levels of C-reactive protein(CRP)were(5.25±1.48)and(5.72±1.62)mg·L-1;levels of tumor necrosis factor-α(TNF-α)were(45.33±4.61)and(46.95±5.24)ng·L-;the difference was not statistically significant(all P＞0.05).During treatment,there were significant differences in total incidence of adverse reactions between retroauricular injection group and tympanic injection group(23.21％vs 51.67％,P＜0.05).There were 11 case times of local pain and 4 case times of vertigo in retroauricular injection group,while there were 30 case times of local pain and 15 case times of vertigo in tympanic injection group.Conclusion Retroauricular injection or tympanic injection of methylprednisolone sodium succinate combined with hyperbaric oxygen therapy has the comparable curative effect in patients with nerve deafness;the two administration modes both can promote hearing recovery,relieve reduce oxidative stress and inflammatory response.However,retroauricular injection has lower incidence of local pain and vertigo.
