听力损失程度和听阈图型与突发性聋预后关系探讨

To investigate the relation of sudden deafness with hearing loss level and auditory threshold

目的:探讨听力损失程度和听阈图型与突发性聋预后关系。方法:回顾性分析我科收治的92例(97耳)突发性聋患者的临床资料。结果:上升型和反盔型听力损失预后最好,总有效率均为100.0%;缓降型其次,总有效率70.0%(7/10);全聋型总有效率为66.7%(14/21),陡降型较差,有效率为50.0%(4/8)。虽然全聋治疗总有效率高于陡降型,但无一耳痊愈,而陡降型有1耳痊愈。另全聋治疗后有6耳仍为全聋,1例提高65dBHL,1例提高50dBHL。耳聋程度中,轻、中度各1耳,虽然总有效率最高,但均未痊愈,经治疗后,听力各提高17dBHL和19dBHL,中重度、重度、极重至全聋总有效率差异无统计学意义(P>0.05),但是痊愈率均差异有统计学意义(均P<0.01),中重度组痊愈率最高38.5%(10/26耳),其次重度组,痊愈率为33.3%(12/36耳),极重至全聋最差为6.0%(2/33)。结论:耳聋的程度与总有效率无明显关系,但与痊愈率差异有统计学意义,突发性聋的不同听阈图型与听力的预后极为相关。

Objective： To investigate the relation of sudden deafness with hearing loss level and auditory threshold. Method：A retrospective analysis was performed in 92cases（97ears） of sudden deafness patients. Result： In this group,the best hearing loss prognosis was the ascend type and the back type the total effective rate was both 100.0%. The second was the slow descend type . the total effective rate of this type was 70.0%（7/10）. the total effective rate of full deaf is 66.7% （14/21）, the sudden descend type is poor, the effective rate was 50% （4/ 8）. although the full deaf group＇s total effective rate was high than sudden descend type, without one ear completely rrecovering, and only one ear from sudden descend type was completely cured. After treatment, there were 6 ears of fall deaf in full deaf group. There was one case rised 65 dBHL and one case rised 50 dBHL from the 21 cases full deaf sufferer. In this deaf level group, the light 1 evel and the middle level was one ear respectively. Although the total effective rate of this group was the highest, all the cases were not completely recovered. After treatment,the hearing rise 17 dBHL and 19 dBHL respectively. After X^2 text（X^2 =1. 459, P 〉0.05） ,the total effective rate of the more hearier,heavy, and the heavest to full deaf was no significant difference . but after .X^2 text （X^2=10.09, P 〈0.01 ）, the full recover rate was significant difference. The more heavier level group＇s full recover rate was the highest 38.5%（10/26） ,the second was heavy level group ,the full recover rate is 33.3%（12/36） ,the worst level to full deaf group was the lowest：6.0% （2/33）. Conclusion：It was considered that the deafness level was no obvious relation to the total effective rate , but there was significant difference in fully recover rate. The different auditory threshold figure of the sudden deafness was closely related to the hearing＇s progno sis.
