Pneumolabyrinth is an uncommon condition in which air bubbles in the labyrinth are described, although its underlying pathophysiology is still not widely understood. It may be associated with barotrauma, stapedial surgery, cochlear implantation, head trauma, and temporal bone fracture. When it occurs, it is ususally identified on high-resolution computed tomography of the temporal bone and an early surgical intervention leads to a more rapid resolution of vestibular symptoms and preservation of existing auditory function. Recently, the authors have experienced two cases of pneumolabyrinth resulting from trauma. Hence, we report two cases with a review of literature.
