title: Acoustic biast trauma.
abstract: In this study 26 cases of blast injury to ear were studied. Both ears were affected in 9 cases and therefore the number of ears studied being 35. The audiological findings along with the treatment and a followup of 2 years is presented.We found that mixed deafness was commonest and the sensorineural element of the hearing loss started recovering before conductive element, but recovery slowed down later on and was incomplete in most cases. Approximation of torn fragments of tympanic membrane improved its healing. Vertigo lasting for 1-7 days was present in 46.15% of cases. Only one patient had perilymph fistula which was repaired.
