ABSTRACT
Hearing loss is the most frequent complication of temporal bone injury. Cochleovestibular disorders may even cause disability. The conductive component of posttraumatic hearing loss is often caused by the solution of continuity of the auditory bone chain. Here, dislocations are much more common than auditory bone fractures. In diagnostics of these damages, the “golden” standard is the computed tomography with 3D image reconstruction, especially in cases of closed-ear injury. However, ossicular damages do not explain the perceptive component of hearing loss, which is often associated with the formation of perilymphatic fistulas of the labyrinth windows (PFLW). When diagnosing the latter, the “loading” audiometric tests are of special importance. In this regard, we describe a clinical case where rehabilitation of auditory-vestibular abnormalities was achieved in a 19-year-old patient.
