“…Of these factors, transient middle ear disorders have received considerable attention. The high incidence of middle ear effusion among neonatal intensive care unit infants (Balkany, Berman, Simmons, & Jafek, 1978;Derkay, Bluestone, Thompson, Stephenson, & Kardtzke, 1988;McLellan, Strong, Johnson, & Dent, 1962;Paradise, 1981;Proctor & Kennedy, 1990; Stockard & Curran, 1990) and the presence of residual substance and fluid in the middle ear cavity of newborn infants (Buch & Jorgensen, 1964;Proctor, 1964) have been suggested as potential contributors to the so called "inaccuracy" in ABR newborn auditory screening. Unfortunately, the conventional indices for detecting middle ear pathology such as otoscopic examination and tympanometry have proven to be difficult in the case of the former Groothius, 1982;Schreiner & Kiesling, 1981) and unreliable in the latter (Paradise, Smith, & Bluestone, 1979;Schwartz & Schwartz, 1978) with newborn infants.…”

Auditory Brain Stem Responses to Air- and Bone-Conducted Clicks in the Audiological Assessment of At-Risk Infants

et al. 1993

Auditory brain stem responses [ABRs] to a i r and boneconducted clicks were used to assess the auditory status of 170 atirisk neonates. During the perinatal period, 20.6% [35/170 cases] of the at-risk infants failed ABRs to airconducted clicks at 30 dB nHL in a t least one ear. Earspecific results indicated an initial failure rate of 15.0% [51/340 ears]. Approximately twctthirds (32/51 ears] of these initial failures showed purely conductive deficits, whereas the remaining one-third [ I 9/51 ears] involved suspected sensorineural components. Follow-up audiological evaluations were performed for 87.1% ( 1 4 8 cases] of these atirisk infants at 4 mo and/or 1 yr corrected age. Based on the initial tests and followup assessments, the tentative operating characteristics of ABRs to both a i r and boneconducted clicks for identification of sensor ineural deficits in at-risk neonates were calculated. It was found that the ABR to boneconducted clicks yielded better specificity, predictive value of positive results, and overall efficiency. It is suggested that the ABR to boneconducted stimuli should be viewed as a valuable addition in the assessment of cochlear reserve in infants who fail a newborn auditory screening to airconducted stimuli.

“…A false positive response may be caused by transient ear canal and/or middle ear dysfunction due to vernix occluding the ear canal, or residual amniotic fluid or mesenchyme in the middle ear space of well babies Rosenfeld et al, 2004;Thornton, Kimm, Kennedy, & Cafarellidees, 1993). Infants cared for in the neonatal intensive care units (NICU) are prone to a conductive pathology due to mechanical ventilation for long period of time ; L. R. Proctor & Kennady, 1990). Transient outer and middle ear dysfunction is common in infants tested within 48 hours of birth and babies in the NICU for extended periods of time .…”

Sweep frequency impedance measurements for evaluation of middle ear function in young infants

Aithal¹

This thesis investigates sweep frequency impedance (SFI) measurements for evaluation of middle ear function in young infants. The thesis is presented as a series of published papers in international journals. The thesis consists of seven chapters each with a different focus of research. The seven chapters are described as follows:Chapter 1 provides a review of the literature on, false positive responses in newborn hearing screening (NHS) program, external/middle ear dysfunction in newborns and young infants, overview of currently available audiological and non-audiological diagnostic tools for the assessment of outer and middle ear functions in young infants, and the background of current situation of SFI measurements, knowledge gaps and research questions.Chapter 2 investigates the feasibility of testing neonates using the SFI technique and development of clinical norms for SFI measures in healthy neonates. This study has been
