Characterization of hearing loss in Waardenburg syndrome
Keywords:
Waardenburg syndrome/epidemiology, Hearing loss.Abstract
Introduction: sensorineural hearing loss is one of the main symptoms of Waardenburg syndrome. Twenty six (26) individuals of a family living in Sandino municipality are carriers of this genetic entity.
Objective: to characterize hearing loss in people affected by Waardenburg syndrome.
Material and methods: a descriptive, longitudinal and prospective study was carried out with people affected by hearing loss belonging to a family who suffers from Waardenburg syndrome in Sandino municipality.
Results: this research incorporates important aspects of hearing loss in cases affected by Waardenburg syndrome, not described before, offering the possibility to present them in a new way to develop and update knowledge about this genetic disease.
Conclusions: sensorineural hearing loss analyzed in these cases presented a cochlear location, although in some cases, associated retrocochlear injury is not discarded, and its intensity may be increased by noise exposure.
