作者在5年中所见到的低频感音性聋,47例为美尼尔氏病,21例为其他耳聋。后组中6例发生于镫骨切除术后,3例是由于圆窗外淋巴瘘,1例头颅外伤后,1例为大脑顶叶脑膜肉瘤;余10例为双耳聋,其中3例可能为遗传性,1例为先天性疾病引起,1例流感性脑膜炎后,5例诊断不明。作者对镫骨切除术后及圆窗膜破裂发生的低频感音聋进行了详细的叙述。并对外淋巴液通过前庭窗或圆窗的慢性丢失引起的内淋巴积水进行了讨论。低频感音聋多见于美尼尔氏病,但并非全部美尼尔氏病皆表现这样类型的听力减退。本文资料美尼尔氏病40%以上为低频感音聋。本病的特点为听力波动,听力曲线可在几小时内由上升型变为平坦型,由于反复发作亦可发展为高频损
The authors saw deafness in low frequency in five years, 47 cases of Meniere’s disease and 21 cases of other deafness. Six cases occurred in the posterior group after tarsalotomy, three cases were due to round window of lymphatic fistula, one case of cranial trauma, one case of parietal lobe meningioma; the other ten cases were bilateral deafness, of which three cases may be genetic 1 case of congenital disease, 1 case of influenza meningitis, 5 cases of unknown diagnosis. The author described in detail the low-frequency sensorial deafness after tarsal osteotomy and round window membrane rupture. In addition, the discussion of perilymph fluid caused by chronic loss of the vestibular window or round window. Low-frequency sensorial deafness is more common in Meniere’s disease, but not all Meniere’s disease shows this type of hearing loss. This article information about 40% of Meniere’s disease for low-frequency sensorineural hearing loss. The disease is characterized by hearing fluctuations, the hearing curve can be changed from rising to flat within hours, due to recurrent episodes can also develop into high-frequency loss
