摘　　要：本文分析病程２周内的特发性突聋１０９例的有眩晕及无眩晕两组病人的听力损失类型及预后。发现：女性合并眩晕多于男性（６１．８％：３７．３％，Ｐ＜０．０５）。有眩晕病人平均年龄高于无眩晕病人（Ｐ＜０．０５）。１０９例中深度耳聋（ＰＨＬ）型占４１例（３７．６％），平坦听力损失（ＦＨＬ）型３１例（２８．４％），高频听力损失（ＨＨＬ）型２５例（２２．９％），低频听力损失（ＬＨＬ）型９例（８．３％），中频听力损失（ＳＨＬ）碟型３例（２．８％）。１０９例中突聋有眩晕者占４５％。各型突聋的眩晕发生率分别为：ＰＨＬ型６８．３％，ＦＨＬ型３５．５％，ＮＨＬ型３２．０％，ＬＨＬ型１１．１％。本组以ＰＨＬ型为主的高频耳聋眩晕发生率较高，可能是耳蜗基底转病变累及邻近前庭器所致。治疗结果显示：突聋有眩晕及无眩晕两组听力改善率无显著性差异，但突聋发病７天以内组经治疗听力改善率高于７天以上组（７６．１％：５２．６％，Ｐ＜０．０１）。The Pattern of audiogram and progriosis of 109 patients with sudden deafness with and without vertigo within 2 weeks of the onset of the hearinky loss were evaluated.Sudden deafness with vertigo occurred much more frequently in female than in male(P<0.05).The age of 78 percent patients ranged 26 to55years.The patterns of audiogram of 109 patients were as follows:profound hearing loss(PHL)n 41 patients(37.6%),flat-type hearing loss(FTHL)in 31 (28.4%),high-tone hearing loss(HHL)in 25(22.9%),low-tone hearing loss(LHL)in 9(8.3%),saucer-type hear-ing loss is 3(2.8%).Vertigo occured most frequently in patients with PHL(63.3%),fol-lowed by FTHL(35.5%),HHL(32.0%), and LHL(11.1%).Severe hearing loss in high-tone frequencies with vertigo may relate to cochlear basal turn being niore proxirnal to the vestibular apparatus than the upper tunr.The results of treatment showed that there was no significant difference of hearing recovery between sudden deafness with and without vertigo,but hearing recovery of sudden deafness treated in seven days of the onset was better than that seven days iater.
