突聋不同听力曲线类型的临床分析

Clinical analysis on treatment course of sudden sensorineural hearing loss with different audiometric curves

摘要:

目的观察突发性耳聋不同听力曲线类型患者的静脉给药治疗疗程及疗效，有助于为临床静脉输液治疗的适宜疗程提供依据。方法82例（92耳）突发性耳聋患者给予改善微循环、溶栓、激素、营养神经等常规治疗，比较不同听力曲线类型的突聋患者的治疗效果及治疗疗程。结果低中频型治疗总有效率最高（84.62%），治疗7 d内有效率与治疗14 d内总有效率差异无统计学意义（P=0.16>0.05）；全频型治疗总有效率为59.70%， 治疗7 d内总有效率与治疗14 d内总有效率差异有统计学意义（χ2=5.04，P<0.05）；中高频型和高频型治疗总有效率分别为20%和57.14%。结论低中频型听力损失的患者静脉输液治疗7 d内恢复的可能性高；全频型听力损失的患者静脉输液治疗7~14 d恢复的可能性高。

Abstract:

ObjectiveToprovidefoundation for propertreatment course durationof intravenous administration for sudden sensorineural hearing loss(SSHL) via comparing the administration course and clinical effect inpatients with different audiometric curves.Methods82 cases(92 ears) of SSHL were given routine treatment including microcirculation improvement, thrombolysis, glucocorticoid and neurotrophy. Their effect and treatment course of SSHL with different audiometric curveswere compared.ResultsThe total effective rate of patientswith hearing lossatlow to moderate frequencies was 84.62%, and the difference between the effective rate with treatment duration of 7 days and that of 14 days was statistically insignificant (P>0.05).The total effective rate of patientswith hearing lossat all frequencies was59.70%, and the difference between the effective rate with treatment duration of 7 days and that of 14 days was statistically significant (P<0.05). The total effective ratesatmoderateto high frequencies and high frequencies were20% and 57.14%respectively.ConclusionThe SSHLpatients withhearing lossatlow to moderate frequencies mayhave high possibility of recovery within 7 days of intravenous administration, while those with all frequenciesmay get recovered in 7 to 14 days of administration.
