When acoustic neuromas are found in younger age groups, they are typically bilateral and associated with neurofibromatosis (NF). A unilateral acoustic neuroma in a child or adolescent without NF is rare. We report audiometric, auditory brainstem response (ABR) and magnetic resonance imaging (MRI) data for a 15-year-old male with an acoustic neuroma but(More)
This study investigated the characteristics of hearing loss in children with ventriculoperitoneal (VP) shunted hydrocephalus. Twelve hydrocephalic children with patent VP shunts participated. The etiology of the hydrocephalus was either intraventricular hemorrhage or spina bifida. Audiometric examination included pure-tone air conduction thresholds,(More)
Often ABR threshold testing employs clicks to assess high-frequency hearing, and low-frequency tone bursts to assess low-frequency sensitivity. While a maturation effect has been shown for click stimuli, similar data are lacking for low-frequency toneburst stimuli. Thus, 305 infants ranging in conceptional age (CA) from 33 weeks to 74 weeks were tested.(More)
The purpose of the present investigation was to (1) determine the short-term test-retest reliability of the transient-evoked otoacoustic emission (TEOAE) parameters of echo level and reproducibility, as produced by the Otodynamic's ILO88 system; and (2) assess the ability of the ILO88 parameters of frequency spectrum, echo level, and reproducibility to(More)
A phenomenon associated with a monaural hearing aid fitting has previously been identified. In some individuals with bilateral sensorineural hearing loss (BSNHL), the speech-recognition score (SRS) of the unfitted ear deteriorates over time. Nine subjects with BSNHL who chose a monaural hearing aid fitting are chronicled from the time of their initial(More)
As a group, adults with bilateral symmetric sensorineural hearing loss (SNHL) who receive a monaural hearing aid fitting experience a progressive decline in their word recognition score (WRS) for monosyllabic word materials in the unaided ear but not in the aided ear. However, adults with binaural fittings do not demonstrate a similar deterioration in their(More)
The effectiveness of three central auditory processing (CAP) tests was evaluated using clinical decision analysis (CDA) procedures. The tests under study were the Dichotic Digits Test (DDT), the Auditory Duration Patterns Test (ADPT), and the P300 evoked potential test (P300). Subjects with normal hearing, sensorineural hearing loss (SNHL), and central(More)
OBJECTIVES Historically, audiological procedures have focused on the assessment of the afferent (ascending) cochlear-VIIIth nerve system and have, for the most part, ignored the efferent (descending) auditory system. We report afferent and efferent auditory test results for two cases with a cholesterol cyst of the right petrous apex; one lesion involves the(More)
Historically, the ipsilateral acoustic reflex (IAR) has played a prominent role in middle ear screening protocols. However, in 1990, the American Speech-Language-Hearing Association's revised guidelines, "Screening for Hearing Impairment and Middle Ear Disorders," deleted the IAR as a screening parameter. This decision was based on studies that demonstrated(More)
