title: Effects of blast overpressure on the ear: case reports.
abstract: The case histories of five patients who experienced blast overpressure in excess of 200-dB peak pressure level are presented. Despite the significance of the sound pressure levels received in a military training accident and the severe injuries that resulted from the blast, these individuals experienced substantial improvement of hearing 1 year later. Undoubtedly, successful surgical intervention and medical management were the primary contributors to the restoration of hearing. Audiometric data are presented documenting hearing status within 2 to 3 weeks postinjury and following final surgical remediation of the resulting middle ear damage. A review of these cases offers insight into the possible prognosis of patients with similar injuries.
