“…The most commonly reported neonatal conditions associated with auditory neuropathy/dyssynchrony are anoxia and hyperbilirubinemia (Stein et al, 1996;Berlin et al, 1997;Deltenre et al, 1999;Rance et al, 1999;Simmons and Beauchaine, 2000;Starr et al, 2000;Sininger and Oba, 2001;Franck et al, 2002;Madden et al, 2002;Dunkley et al, 2003). More than 50% of early onset AN/AD cases presented thus far have shown one or both of these conditions in their neonatal histories.…”

Auditory neuropathy/dys-synchrony is a form of hearing impairment in which cochlear outer hair cell function is spared but neural transmission in the auditory pathway is disordered. This condition, or group of conditions with a common physiologic profile, accounts for approximately 7% of permanent childhood hearing loss and a significant (but as yet undetermined) proportion of adult impairment. This paper presents an overview of the mechanisms underlying auditory neuropathy/dys-synchrony-type hearing loss and the clinical profile for affected patients. In particular it examines the perceptual consequences of auditory neuropathy/dyssynchrony, which are quite different from those associated with sensorineural hearing loss, and considers currently available, and future management options.

“…Administration of certain antibiotics and diuretics in neonatal intensive care units has also been implicated in the development of the AN/AD profile [14]. Hyperbilirubinemia and hypoxia seem to prevail among the risk factors [6,8,[16][17][18]. More than 50% of early-onset AN/AD cases reported in the literature so far, have a medical history that includes exposure to either one (or both) of these factors [10].…”

“…Meanwhile, clinical interest in tests of otoacoustic emissions (OAEs) have challenged the broad use of the ABR for newborn screening, yet screening-ABR methods and instrumentation have continued to evolve. Currently, ABR testing forms part of many newborn hearing screening programs, particularly in relation to the detection of auditory neuropathy, which would be missed via OAE screening alone (Madden et al, 2002;Dunkley et al, 2003;Berg et al, 2005).…”

Call for calibration standard for newborn screening using auditory brainstem responses

The mode of stimulation employed in newborn screening of the auditory brainstem response has evolved from the clinically standardized supraaural earphone to the tubal insert earphone, to most recently a circumaural earphone developed for this test. Considered here is the need to develop a standard for calibration of such devices for newborn screening applications, in particular. At risk is the prospect of missing the milder degrees of hearing loss, assuming a goal of detecting all clinically-significant congenital hearing losses. Two commercially manufactured test instruments for automated newborn screening were scrutinized via bench testing of sound output from their respective transducers, using a variety of measurements. By convention or design, none of the measurement approaches involved a model of the newborn ear, per se. While it was concluded that the manufacturers' method shows promise, namely as a relatively simple and potentially reliable method of calibration, concerns arose regarding output levels when measured according to both the manufacturers' and the authors' methods. Further work is needed to critically assess calibration methods and to establish, to the extent possible, appropriate norms and validation studies in newborns to provide a better understanding of the actual sound pressure level of the screening stimulus.
