The stapedial reflex as a topographical marker of proximal involvement of the facial nerve in leprosy. A pilot study.
This study aimed to determine the parameters necessary for a study of stapedial reflexes in leprosy patients to ascertain if the facial nerve is involved more proximally than the stylomastoid foramen. It involved leprosy patients with and without facial nerve involvement and non-leprosy controls. Cl...
Threshold and suprathreshold temporal integration effects in the crossed and uncrossed human acoustic stapedius reflex.
Our results showed that reflex thresholds were significantly lower for the uncrossed condition and for longer duration stimuli. Both effects were dependent on threshold response criteria. Threshold TI measurements in both crossed and uncrossed conditions were equivalent at low criterion levels (0%-4...
Tympanic membrane displacement testing in regular assessment of intracranial pressure in eight children with shunted hydrocephalus.
The TMD test can be used on a regular basis as a reproducible investigative tool in the assessment of ICP in children with shunted hydrocephalus, thereby reducing the need for invasive ICP monitoring. The equipment necessary to perform this testing is mobile. It will provide a useful serial guide to...
Menière's disease in the elderly.
Reduced active protection to the cochlea during physical exercise.
The present investigation was designed to evaluate whether dynamic physical exercise is able to modify stapedius reflex (SR) activity and, as a consequence, to influence the amount of temporary threshold shift (TTS). Experimental subjects were 10 normal-hearing male volunteers, aged 27-34 years (mea...
Predicting hearing aid response in real ears.
A hearing aid fitted to different ears will produce very different sound pressure spectra in the ear canal. In addition, this variation in response is different among hearing aids. A description in terms of an electrical analog model of the ear and hearing aid system is given. The applicability of t...
[Effects of diazepam on stapedius reflex: physiological research].
The effect of diazepam (10 mg i.m. X 7 days) on crossed and uncrossed acoustic stapedius reflex parameters (threshold, amplitude and duration) has been studied in 7 normal hearing subjects. The results showed that diazepam has a not clinically significant damping effect on the threshold, the amplitu...
Outcomes after laser stapedotomy with and without preservation of the stapedius tendon.
We performed a retrospective review by mailing extensive questionnaires to patients who had been operated on between 1994 and 1997. We also performed routine and special audiometric testing to augment the subjective data. Seventy-nine of 124 questionnaires (64%) were returned. Of the respondents, 75...
[Contralateral modification of transitory evoked otoacoustic emissions].
Traditionally, suppressing effects of contralateral stimulation on TEOAE have been attributed to cochlear efferents (CEs). Occasionally, the middle-ear muscle and cross hearing involvement have been considered as well. Substantially, the present results and findings of other workers are inconsistent...
Stapedial reflex and ears with high static acoustic admittance.
Based on this sample, it is suggested that a patient presenting with high peak compensated static acoustic admittance (peak Y(tm) > or = 2.1 mmho) undergo ASRT evaluation with the ear canal pressure set to -50 daPa (relative to TPP)....
