OBJECTIVE The aim of the present work was to investigate the therapeutic effects of glycerol on the distortion-product otoacoustic emissions in guinea pigs in which experimental endolymphatic hydrops had been surgically induced. METHODS Thirty albino guinea pigs were used. The experimental protocol considered three groups of guinea pigs (10 animals each).(More)
Distortion Product Otoacoustic Emissions (DPOAEs) are elicited by simultaneous application of two tones to the ear canal. These emissions are a result of nonlinear mechanical characteristics of the cochlea at a specific point and have a precise mathematical relation with the frequencies of the two eliciting primary tones f1 and f2. This frequency-selective(More)
Auditory fatiguing can be considered a suitable test to assess some cochlear mechanisms and diseases otherwise not easily detectable. Since spontaneous otoacoustic emissions (SOAEs) originate from active sources within the cochlea they show sensitive and early vulnerability to noise, displaying informative time-courses after overstimulation in the short(More)
OBJECTIVES To introduce the Italian adaptation of the STARR test based on a roving-level adaptive method to mimic challenging real-life listening conditions for use in people with auditory prostheses. DESIGN Normative data were collected and interlist-variability, as well as learning effects, were investigated using a within-subject design with repeated(More)
The present investigation was designed to measure distortion-product otoacoustic emissions (DPOAEs) in a group of guinea pigs with endolymphatic hydrops in order to obtain normative data in this particular field. The-DPOAE's results were compared with compound action potential (CAP) outcomes to analyze the value of DPOAE measurements in audiologic(More)
OBJECTIVES To assess the therapeutic effectiveness of an intratympanic (IT) steroid protocol compared to a systemic steroid protocol. METHODS A total of 265 consecutive patients presenting unilateral idiopathic sudden sensorineural hearing loss were divided into 2 groups. One group comprised 131 patients enrolled between May 2009 and May 2010, and the(More)
The 2f1-f2 distortion product otoacoustic emission (DPOAE) is suppressed by a third tone following a frequency selective pattern and outlining tuning curves which are generally similar to neural and psychophysical findings. The most effective suppressor tone lies between f1 and f2; less suppressive effects are produced by an added tone that lies in the(More)
OBJECTIVES Referential communication (RC) is a key element in achieving a successful communication. This case series aimed to evaluate RC in children with unilateral cochlear implants (CIs) with formal language skills within the normal range. METHODS AND MATERIALS A total of 31 children with CIs, with language development within the normal range, were(More)
