Theossicular chain damage is found in both mucosal and squamosal types of COM. We aim to evaluate relationship between preoperative otologic features, pure tone audiometric findings and intraoperative ossicular chain status in patients with chronic otitis media. <strong>Material and Methods:</strong> 100 patients of either sex aged between 12 to 60 years operated for active or inactive, squamosal or mucosal chronic otitis media attending Ram Lal Eye and ENT Hospital, Government Medical College Amritsar were taken. The preoperative ossicular chain status based on set parameters was compared with the intraoperative ossicular chain status. <strong>Results:</strong> The ossicular chain integrity is more commonly compromised in squamosal COM and the most common ossicle eroded is Incus. Pure tone audiogram has got a very important role in determining the ossicular chain integrity preoperatively and must be done in all cases with accuracy. <strong>Conclusion:</strong> It is concluded that on the basis of otoscopic examination and pure tone audiometry values, we can accurately classify the COM as mucosal or squamosal type and get an idea of the ossicular chain integrity preoperatively hence planning the extent of surgery.展开更多

Materials and methods: This is a prospective study conducted in patients who attend our OPD. After an otorhinolaryngeal examination, all the patients were subjected to pure tone audiometry using MAICA-MA52 audiometer. Results: Our study comprises 1012 males (64%) and 563 females (36%). Out of this, about 15% have conductive deafness and 42% have sensorineural hearing loss. About 29% suffer from mild hearing loss, 26% moderate and 11% severe hearing loss. The alarming information is that about 5% have total hearing loss of Sudden Sensorineural type (SSNHL). Conclusion: Pure tone audiometry is cost effective and easy to perform. Early diagnosis and timely intervention will reduce the morbidity of deafness in our country. Hence it is necessary to identify and treat sudden sensorineural hearing loss and noise induced hearing loss at an early stage.展开更多

文摘目的探讨短纯音刺激皮层听觉诱发电位(cortical auditory evoked potentials,CAEP)对听力评估的价值。方法受试者为听力正常成人19例(36耳),感音神经性聋成人患者21例(21耳),以500、1000、2000和4000 Hz短纯音作为刺激声,在醒觉状态下颅顶电极记录CAEP的N1-P2复合波,分析N1-P2阈值与纯音听阈的相关性,以及两者差值在不同人群中的差异。结果所有受试者四个测试频率的N1-P2阈值与对应频率纯音听阈值的相关系数依次为0.971、0.967、0.958、0.955,呈显著的线性相关;听力正常组36耳500、1000、2000和4000 Hz的N1-P2阈值上限(95%置信区间)依次为32、27、32、39 dB SPL,即正常人阈值上限为32.5 dB SPL;正常人N1-P2阈值与纯音听阈的差值依次为18.9±6.1、11.6±5.9、13.3±7.0、18.7±8.3 dB;感音神经性聋患者两者差值依次为10.3±6.0、6.8±8.9、6.5±9.5、12.9±11.4 dB,四个测试频率的差值在两组人群中的差异均有统计学意义(P<0.05)。结论听力正常人短纯音CAEP的N1-P2平均阈值小于32.5 dB SPL;N1-P2阈值与对应频率纯音听阈相关性非常好,听力评估中使用N1-P2阈值预测听力时应注意刺激声的校准及校正值的使用。
