Abstract：
Clinical findings on cartilage conduction hearing aids (CCHAs) have gradually become clear; however, few reports include a large number of cases. This study included 91 ears from 69 patients who underwent CCHA fitting in our hospital. Their ears were divided into six groups (i.e., bilateral aural atresia or severe canal stenosis, unilateral aural atresia or severe canal stenosis, chronic otitis media or chronic otitis externa with otorrhea, sensorineural hearing loss, mixed hearing loss, and conductive hearing loss) according to their clinical diagnosis and type of hearing loss. Most clinical diagnoses were aural atresia or meatal stenosis (bilateral, 21.8%; unilateral, 39.6%). The purchase rate of CCHAs was higher in the closed-ear group (bilateral, 77.3%; unilateral, 62.5%). In the bilateral closed-ear group, air conduction thresholds at 1000, 2000, and 4000 Hz and aided thresholds with CCHAs at 4000 Hz were significantly lower in the purchase group than the non-purchase group. No significant difference was observed between the purchase and non-purchase groups in the unilateral closed-ear group. In the bilateral closed-ear group, air conduction thresholds and aided thresholds were associated with the purchase rate of CCHAs. In the unilateral closed-ear group, factors other than hearing might have affected the purchase rate of CCHAs.
摘要：
软骨传导助听器（CCHAs）的临床发现逐渐变得清晰；然而，很少有报告包括大量病例。这项研究包括在我们医院接受CCHA拟合的69例患者的91耳。他们的耳朵分为六组(即，双侧耳道闭锁或严重管狭窄，单侧耳道闭锁或严重管狭窄，慢性中耳炎或慢性外耳炎伴耳漏，感觉神经性听力损失,混合性听力损失,和传导性听力损失）根据他们的临床诊断和听力损失类型。大多数临床诊断为耳道闭锁或胃部狭窄（双侧，21.8%；单边，39.6%）。闭耳组的CCHA购买率较高(双侧，77.3%；单边，62.5%）。在双侧闭耳组中，1000、2000和4000Hz的空气传导阈值和4000Hz的CCHA辅助阈值在购买组中明显低于非购买组。在单侧闭耳组中，购买和非购买组之间没有观察到显着差异。在双侧闭耳组中，空气传导阈值和辅助阈值与CCHA的购买率相关。在单侧闭耳组中，听力以外的因素可能会影响CCHA的购买率。
