Marathon Bombing Bystanders Still Suffering Hearing Loss

Boston health experts say that many of the 100-plus individual treated for hearing problems tied to the explosions during the Boston Marathon bombings last year are still suffering persistent or worsening hearing loss.
 
A new study of patients, published in the journal Otology & Neurotology, finds blast-related trauma affecting the ears and hearing is a “major source” of continuing problems among those near the blast site.
 
Lead researcher  Aaron Remenschneider, M.D.,  of Massachusetts Eye and Ear Infirmary, tracked 94 of more than 100 patients evaluated at Boston-area hospitals and clinics. The study found  only 7 percent of patients had any hearing-related symptoms before the attack, but that after the bombings many reported hearing losses — and some of those complaints have persisted.
 
"Acute otologic trauma following the dual blasts was immediately apparent," said Dr. Remenschneider. "However, the extensiveness was not appreciated until the days and weeks that followed."
 
The most common type of injury was a ruptured eardrum, with 48 patients experiencing the condition and 14 patients having perforations in both ears. Overall, 90 percent of patients hospitalized for other injuries had ruptured eardrums on examination.
 
In 38 percent of cases, the ears healed on their own, but those with larger ruptures required surgical repair. All patients also expressed concern about hearing loss or tinnitus (ringing in the ears).
 
A year later, the researchers found that among 44 patients, 80 percent had reduced hearing and 68 percent had new or worsened tinnitus. Other symptoms included increased sensitivity to sound and dizziness or balance problems.
