Findings could provide predictor for degree of hearing loss in children with enlarged vestibular aqueduct
CLEVELAND, Ohio -- It may be possible to predict the severity of hearing loss for children diagnosed with enlarged vestibular aqueduct, according to a new study published in JAMA-Otolaryngology-Head & Neck Surgery. This retrospective chart review, authored by physicians and researchers within the University Hospitals Rainbow Babies & Children's Enlarged Vestibular Aqueduct (EVA) Research Project, is one of the first such studies to find a direct connection between the increasing width of the vestibular aqueduct and the degree of hearing loss a child experiences over time.
"There is still much to learn about the true causes and impacts of EVA," says Mustafa Ascha, MS, first author of the study and a researcher within the UH Rainbow Department of Otolaryngology. "The hope is that these findings will help parents of young children with EVA, and their physicians, better understand what lies ahead for their child's hearing and speech based on the severity of that child's malformation."
The study analyzed the medical records of 52 children diagnosed with EVA from the UH Rainbow Department of Otolaryngology, selecting records with both a computerized tomography (CT) scan for diagnosis and a median of five sets of audiogram test data to measure speech reception threshold, or the minimum intensity of decibels at which a patient can recognize half of spoken words, and the percent of words the patient recognized. The longitudinal models used in the study are common in social sciences such as economics or sociology, but applications in biomedical research are still gaining traction. Continue reading
