Branchiootorenal (BOR) Syndrome: The search for appropriate monitoring

Branchiootorenal (BOR) Syndrome: The search for appropriate monitoring Track: Audiological Services Authors: Catherine LeRoy, B.S.; Emily Nightengale, Au.D.; Affiliations: 1) Children’s Hospital of Colorado, Aurora, Colorado; Presenter: Catherine LeRoy Branchiootorenal (BOR) Syndrome is an autosomal dominant genetic mutation that was first categorized in 1975 by Melnick et al. and included the following symptoms: hearing loss, cup-shaped pinnae, preauricular pits, branchial cleft fistulas, and bilateral renal anomalies. According to Chen et al. (1995) hearing loss occurs in 93% of BOR patients, making hearing loss the most common and consistent feature across individuals with BOR Syndrome. However, hearing loss in patients with BOR Syndrome has been documented as ranging from mild to profound in severity; sensorineural, conductive, or mixed in nature; and it can be congenital or late-onset. For the patients that have late-onset hearing loss, there is a persistent question as to when a hearing loss may occur which results in these patients being brought into the audiology clinic frequently for monitoring purposes. In addition to hearing loss and the accompanying audiology appointments, these patients are at a variety of other appointments to address their multitude of medical needs. The purpose of the present study is to complete a comprehensive literature review on the current information regarding BOR Syndrome and hearing loss including type, degree, configuration, and age of onset of hearing loss with the primary goal of determining appropriate follow-up and monitoring procedures for children with BOR in order to help families and professionals better understand expectations and follow-up needs. Key words: Branchiootorenal Syndrome, BOR, hearing loss, late-onset Contact Information: Catherine LeRoy Catherine.choy@childrenscolorado.org
