Prognosis and outcomes of pneumolabyrinth following an oticcapsule violating fracture : a case report

Abstract EN

Background: Pneumolabyrinth consequent to a temporal bone fracture is a rare entity.

It occurs when air enters the vestibulocochlear system due to a pathological communication between the middle and the inner ears.

The diagnosis is usually confirmed radiologically using high-resolution computed tomography imaging.

Pneumolabyrinth is categorized radiologically as follows: vestibular pneumolabyrinth, cochlear pneumolabyrinth and combined pneumolabyrinth.

Case Presentation: We herein describe the clinical presentation and management of pneumolabyrinth in a 43-year-old man, following an otic capsule-violating temporal bone fracture.

After initially caring for the patient conservatively, without improvement, surgical intervention was undertaken.

Unfortunately, hearing was irrecoverable.

Conclusion: Delaying medical and surgical intervention and the location of the air bubbles associated with the combined type contribute to the irrecoverable loss of hearing.

As otic capsule-violating fractures might not be observed initially on brain CT scans, high-resolution and thin-slice CT scans of the temporal bone is crucial when suspecting temporal bone fracture.
