Hearing Loss and Irritability Reporting Without Vestibular Differences in Explosive Breaching Professionals.

Area of Science:

• Military medicine
• Occupational health
• Neuroscience

Background:

• Blast exposure is a significant risk in military operations.
• Protective gear may not fully mitigate cumulative blast overpressure effects.
• Long-term outcomes of repeated blast exposure require further characterization.

Purpose of the Study:

• To assess long-term hearing and vestibular outcomes in experienced military and law enforcement personnel with repeated blast overpressure exposure.
• To compare outcomes between explosives professionals ('breachers') and non-explosives personnel ('non-breachers').

Main Methods:

• Comparative study of experienced breachers and non-breachers.
• Clinical interviews and audiological/vestibular testing.
• Assessment of long-term health outcomes related to occupational blast exposure.

Main Results:

• Breachers showed higher incidence of hearing loss, tinnitus, irritability, and sensory sensitivity compared to non-breachers.
• Memory loss and concentration difficulties were linked to both breaching and combat exposure.
• No significant differences were found in vestibular and ocular motor outcomes between groups.

Conclusions:

• A career involving breaching is associated with hearing problems, irritability, and sensory sensitivity.
• Combat exposure is a confounding factor in assessing long-term blast exposure effects.
• Future research should control for combat exposure when studying occupational blast effects.
