Childhood Sensorineural Hearing Impairment: Unsolved Diagnostic Issues

Abstract

With the successful implementation of the "Newborn Hearing Screening" program in many countries interest has been directed towards the etiologic search of childhood hearing impairment. Studies dealing with the diagnostic approach show substantial heterogeneity of the data complicating any formulation of guidelines. There is a need for a consensual, international approach in order to improve the diagnostic rate and reporting system. The various issues that arise when dealing with the etiologic evaluation of childhood hearing impairment are outlined in this opinion and actions for improvement proposed.
