Abstract

Pneumolabyrinth is an uncommon condition in which air is present in the vestibule or cochlear. It is rarely found, even in otic capsule violating fractures or in transverse fracture of the temporal bone. So far, there is no consensus on management of pneumolabyrinth. We describe two new cases of pneumolabyrinth by penetrating injury with traumatic tympanic membrane perforation. They presented whirling vertigo with moderate conductive hearing loss. Temporal bone computed tomography (CT) clearly demonstrated the presence of air in the vestibule and cochlear.
