A relatively loud sound is audible when a vibrator is attached to the aural cartilage. This form of conduction is referred to as cartilage conduction (CC). In Japan, a new type of hearing aid has been developed using CC and has been available in clinical practice since 2017. A clinical study conducted prior to its launch demonstrated its benefits, particularly in patients with aural atresia who were unable to use air conduction hearing aids. Several studies have been published on the benefits of CC hearing aids since their introduction into clinical practice. Most of the patients included in these studies had canal stenosis or aural atresia, and the purchase rates of CC hearing aids in these patients were relatively high. However, the number of patients with canal-open ears was small, with overall poor results in the trials, with the exception of patients with continuous otorrhea. CC hearing aids are considered a good option for compensating for hearing loss in ears with canal stenosis or atresia in both bilateral and unilateral cases. However, CC hearing aids are not currently considered the first choice for patients with a canal-open ear.
当将振动器附着在耳软骨上时，可以听到相对较大的声音。这种传导形式被称为软骨传导（CC）。在日本，一种利用软骨传导开发的新型助听器已研制成功，并自2017年起投入临床使用。在其推出之前进行的一项临床研究证明了它的益处，特别是对于那些无法使用气导助听器的耳道闭锁患者。自从软骨传导助听器引入临床实践以来，已经发表了几项关于其益处的研究。这些研究中纳入的大多数患者患有耳道狭窄或耳道闭锁，并且这些患者中软骨传导助听器的购买率相对较高。然而，耳道开放的患者数量较少，除了持续性耳漏患者外，试验的总体结果较差。软骨传导助听器被认为是补偿双侧和单侧耳道狭窄或闭锁耳朵听力损失的一个好选择。然而，目前软骨传导助听器不被认为是耳道开放患者的首选。
