Ossicular chain disruption is a typical consequence of temporal bone trauma. However, it can also occur as a result of direct trauma to the ossicular chain due to penetrating injuries. Hearing loss, dizziness, and facial nerve damage could also occur after penetrating middle ear injuries. Multiple ossicular chain disruption is a rare traumatic ossicular complication caused by direct penetrating lesions in the external auditory canal. We present two cases of multiple ossicular disruptions (dislocation of the incudostapedial and malleoincudal joints) after ear-pick injuries, both of which resulted in conductive hearing loss. The condition improved after delayed surgical intervention (ossiculoplasty).
听骨链中断是颞骨创伤的典型后果。然而，它也可能由于穿透伤导致听骨链直接受损而发生。中耳穿透伤后也可能出现听力损失、头晕和面神经损伤。多处听骨链中断是一种罕见的外伤性听骨并发症，由外耳道直接穿透性病变引起。我们报告两例掏耳损伤后多处听骨链中断（砧镫关节和锤砧关节脱位）的病例，两例均导致传导性听力损失。延迟手术干预（听骨成形术）后病情有所改善。
