摘    要:目的 了解全频突发性聋的分型及其治疗效果的差异.方法 对2005年8月至2008年3月就诊的87例全频突发性聋患者进行研究.所有病例均采用甲基泼尼松龙+巴曲酶注射液(东菱迪芙)+血栓通治疗.结果 根据听力下降的速度将全频突发性聋分为缓降型和骤降型,缓降型的有效率及显效率分别为84.4%(27/32)及68.8%(22/32),骤降型的有效率及显效率分别为52.7%(29/55)及32.7%(18/55);缓降型预后明显好于骤降型(P<0.01).根据听力下降的程度将全频突发性聋分为平坦型和全聋型,以平均听阈90 dB作为划分标准时平坦型的有效率及显效率分别为73.3%(44/60)及53.3%(32/60),全聋型的有效率及显效率分别为44.4%(12/27)及29.6%(8/27);平坦型预后明显好于全聋型(有效率P<0.01,显效率P<0.05).结论 全频突发性聋有必要进一步分型.根据听力下降的速度可分为缓降型和骤降型,缓降型预后明显好于骤降型;根据听力下降的程度可分为平坦型和全聋型,全聋型预后较差,以平均听阈90 dB作为平坦型和全聋型的划分标准更为合适.

Analysis of sub-typing in full-frequency sudden deafness
Abstract:Objective To explore the relationship between the sub-typing of full-frequency sudden deafness and its effect in treatment.Methods A series of 87 cases that have full-frequency sudden deafness were studied from Aug,2005 to Mar,2008.All cases were treated with methylprednisolone,Batroxobin and Xueshuantong.Results Based on the frequency of hearing loss,the objectives were divided into suddendrop-down type and slow-drop-down type.The effective percentage and significant effective percentage in sudden-drop-down type were 84.4% (27/32) and 68.8% (22/32) ,respectively.The effective percentage and significant effective percentage in slow-drop-down type were 52.7% (29/55 and 32.7% (18/55) ,respectively.Slow-drop-down type showed a higher effective and significant effective percentage respectively (P<0.01) .Acording to the degree of hearing loss,objectives were divided into flat-type and profoundtype.The effective percentage and significant effective percentage in flat-type were 73.3% (44/60) and 53.3% (32/60) respectively.The effective percentage and significant effective percentage in flat-type were 44.4% (12/27) and 29.6% (8/27) respectively.The flat-type showed a higher effective (P<0.01) and significant effective percentage (P<0.05) for treatment.Conclusions The sudden deafness needs a further classification.According to the frequency of hearing loss.it can be divided into sudden-drop-down and slow-drop-down type.According to the degree of hearing loss,it can be divided into flat-type and profound-type.It would be appropriate to using 90 dB (average hearing threshold) as a criteria for the classification of hearing loss.
