The acoustic reflex in diagnostic audiology: from Metz to present.
نویسنده
چکیده
In 1946, Metz described what was probably the first practical impedance bridge for measurement of the acoustic reflex. Over the next four decades, diagnostic use of the acoustic reflex progressed in parallel with instrumentation refinements. Today, acoustic reflex threshold and decay testing are a routine component of the diagnostic audiology test battery. Recent advances in the measurement of suprathreshold latency and amplitude have further enhanced the diagnostic value of acoustic reflex measurement.

Introduction & Objective: The vestibular system is sound sensitive and the sensitivity is related to the saccule. The vestibular afferents are projected to the middle ear muscles (such as the stapedius). The goal of this research was studying the relationship between the vestibular hearing and the sound-evoked muscle reflex of the middle ear to 500 HZ. Materials & Methods: This study was a cr...
متن کاملFour cases of acoustic neuromas with normal hearing.
In 95 percent of the cases, patients with acoustic neuromas will have some magnitude of hearing loss in the affected ear. This paper reports on four patients who had acoustic neuromas and normal hearing. Results from the case history, audiometric evaluation, auditory brainstem response (ABR), electroneurography (ENOG), and vestibular evaluation are reported for each patient. For all patients, t...
متن کاملStapedial reflex and ears with high static acoustic admittance.
PURPOSE To evaluate modified acoustic reflex diagnostic protocols for a group of individuals (n = 9) with high peak compensated static acoustic admittance (Y(tm)) tympanograms. METHOD A modified procedure designed to improve acoustic stapedius reflex threshold (ASRT) measurements in individuals with high-admittance tympanograms was employed in both an experimental and a control group. ASRTs w...

The purpose of this investigation was to evaluate the sensitivity and specificity of the following acoustic-immittance protocols and their constituent measures for detection of middle-ear effusion in children: (a) tympanometric width; (b) absent ipsilateral acoustic reflex; (c) ASHA guidelines; (d) tympanometric peak pressure; and (e) static-acoustic middle-ear admittance. The middle-ear sample...

UNLABELLED The main issue regarding pediatric audiology diagnosis is determining procedures to configure reliable results which can be used to predict frequency-specific hearing thresholds. AIM To investigate the correlation between auditory steady-state response (ASSR) with other tests in children with sensorineural hearing loss. METHODS Prospective cross-sectional contemporary cohort stud...
