PATIENTS AND METHODS: 62 blast victims who were brought to ENT department CMH Rawalpindi without previous history of ear disease in this duration were studied for type and severity of ear injuries. All cases underwent clinical examination of ear including otoscopy. Pure tone audiometry (PTA) was performed in all the cases. RESULTS: Out of 62 patients, 80.6 %(50) were male and 19.4 %(12) female. Age group varied from 13 to 60 years. Tympanic membrane rupture was the commonest finding present in 64.5%(40) individuals,17.7% (11) had perforation of right TM and 22.6%(14) had left TM perforation. Bilateral TM perforation was present in 24.2% (15) cases. Laceration of pinna was found in 11.2 %(7) patients and hemotympanum was present in 9.65% (6) cases [Fig: 1]. 79% (49) patients had hearing loss greater than 25 dB, out of which 22 were bilateral and 27 cases had unilateral involvement. So total of 71 ears were having hearing loss. 73.2% (52) had mixed hearing loss, 15.5% (11) pure conductive and 11.3% (8) pure sensorineural losses [Fig: 2].
