Two Cases of Multiple Ossicular Chain Disruption After Penetrating Injury and Tympanic Membrane Healing

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 o...

Summary: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).
