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.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
Shock Waves
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high pressures...
