Background: The ear is commonly affected in persons who sustain blast injuries as it is one of the most sensitive pressure transducers in humans. Methods: In this study 146 ears of 73 victims of blast injury were evaluated and followed up for 2 years. Results: In our study we encountered 120 tympanic membrane perforations out of 146 ears examined. Out of which 62.5% cases of tympanic membrane perforation healed spontaneously while 37.5% required tympanoplasty and 2.5% had to undergo revision tympanoplasty. Ossiculoplasty was requires in 29.8% cases. 13.0% had mixed hearing loss, none cases of pure SNHL and 1.6% cases developed cholesteatoma. These results were in congruence to the earlier studies. Conclusion: An observation period of at least 3 months is recommended in tympanic membrane perforation due to blast injury and the results of tympanoplasty are also generally good.
