软骨传导（CC）是一种传导形式，当换能器放置在耳软骨上时，它允许听到相对较大的声音。CC的传导机制已逐渐被阐明，从而允许开发CC助听器（CC-HA），其在日本临床上可用。然而，CC仍然没有被完全理解。本审查总结了CC以前的报告，以便于理解。关于传输机制，发现当换能器附接到耳软骨时，与未附接的条件相比，耳道中的声压级增加。此外，插入耳塞和向耳道中注入水改变了CC阈值，表明软骨-空气传导对传输的影响相当大。在CC中，耳软骨类似于振动扬声器的可移动板。这种独特的转导机制是CC特征的原因。在临床应用方面，CC-HA是耳闭锁患者的良好选择，尽管与骨性闭锁耳的骨传导相比，CC-HA的信号传输较差。CC的优点，即舒适，稳定的固定，美观，和非侵入性，促进其临床使用。
Cartilage conduction (CC) is a form of conduction that allows a relatively loud sound to be audible when a transducer is placed on the aural cartilage. The CC transmission mechanism has gradually been elucidated, allowing for the development of CC hearing aids (CC-HAs), which are clinically available in Japan. However, CC is still not fully understood. This review summarizes previous CC reports to facilitate its understanding. Concerning the transmission mechanism, the sound pressure level in the ear canal was found to increase when the transducer was attached to the aural cartilage, compared to an unattached condition. Further, inserting an earplug and injecting water into the ear canal shifted the CC threshold, indicating the considerable influence of cartilage–air conduction on the transmission. In CC, the aural cartilage resembles the movable plate of a vibration speaker. This unique transduction mechanism is responsible for the CC characteristics. In terms of clinical applications, CC-HAs are a good option for patients with aural atresia, despite inferior signal transmission compared to bone conduction in bony atretic ears. The advantages of CC, namely comfort, stable fixation, esthetics, and non-invasiveness, facilitate its clinical use.
