“…7,36,43,45,46 SNHL is most common, 2 occurring in 35 to 54% of blast injuries. 7,23,33,47,48 For the current conflicts, 64% of the blast-injured patients seen at Walter 22 Drugs such as gentamicin or vancomycin are commonly used to treat soldiers with amputation and polytrauma to combat multidrugresistant organisms. These drugs can be vestibulotoxic and/or cochleotoxic, causing instability and/or dizziness and hearing impairment.…”

The increased use of explosive devices and mines in warfare and excessive noise of weapons has created an unprecedented amount of auditory dysfunction among soldiers. Blast-related injuries may damage the auditory processing and/or balance centers resulting in hearing loss, dizziness, tinnitus, and/or central auditory processing disorders. Some also lead to traumatic brain injury (TBI), postconcussive syndrome (PCS), and/or posttraumatic stress disorder. Some PCS symptoms such as dizziness, loss of balance, hearing difficulty, and noise sensitivity also can signify auditory or vestibular dysfunction and should not be obscured with the PCS package. This article provides information about the mechanisms of blast injury with emphasis on auditory dysfunction and TBI. Audiologists must be prepared to identify those at risk for TBI or mental health problems and adapt audiologic clinical practices to this population. An interdisciplinary comprehensive evaluation of peripheral, central, and vestibular components of the auditory system should be employed in patients with TBI to ensure that auditory dysfunction is accurately diagnosed and that appropriate rehabilitation can be performed.

“…Using the same classification in a sample of patients exposed to explosions Perez et al (2000) found 46% of audiograms with a downward slope configuration, 41% with a dip (notch) configuration, and 12% flat audiograms. Spremo and Stupar (2008) reported the following types: slope at 2000 Hz in 27.1%, slope at 4000 Hz in 25.9%, and flat type in 25.2% of acoustic trauma cases (individuals exposed to explosions).…”

“…The hearing threshold was determined at the following frequencies: 250, 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz. We have used the audiometric configuration cited by Perez et al (2000) to classify the pathologic audiograms, and some other algorithms for the audiograms that did not meet the criteria from the previous classification (Pittman, Stelmachowicz, 2003). The normal hearing was defined as thresholds of ≤ 20 dB hearing level (HL) at the audiometric frequencies from 250 to 8000 Hz, and the pathologic audiogram was defined as an audiogram with the hearing thresholds of > 20 dB HL at any of the frequencies (Adjamian et al, 2012).…”

The aim of the study was to determine the configuration of pathologic audiograms in patients with excessive noise exposure, and to calculate the frequency of notches in the audiogram in patients with and without excessive noise exposure by avoiding the effect of age-related hearing loss. We have analyzed 514 audiograms of 257 patients aged between 20 to 50 years: 240 patients (mean age of 38.7 years) with excessive noise exposure and 17 patients (mean age of 41.2 years) with notches in the audiogram, but without a history of excessive noise exposure. For statistical data analysis we have used the Chi-square test and Fisher exact test with the level of significance p < 0.05. Pathologic audiograms were classified into five different types: Slope at 4000 Hz (0.8%), Slope at 2000 Hz (15.1%), Notch at 4000 Hz (67.4%), Notch at 2000 Hz (0.8%), Flat (8.9%), and 7% were out of this classification. A total of 190 (79.2%) patients with excessive noise exposure had a notch in the audiogram. Left ear notches were the most common. Among the patients with notched audiograms, 91.8% had a history of excessive noise exposure, either occupational or nonoccupational, and 8.2% did not report any excessive noise exposure.
