Effects of Continuous Positive Airway Pressure on Middle Ear Pressure and Acoustic Stapedial Reflex.
OBJECTIVE This study investigated the effects of continuous positive airway pressure (CPAP) on middle ear pressure and acoustic stapedial reflex and the correlation between CPAP and middle ear pressure. STUDY DESIGN Prospective cohort study. SETTING Tertiary hospitals. SUBJECTS AND METHODS Fifty patients with obstructive sleep apnea-hypopnea syndrome were assigned to the study group, and ...
متن کاملThe time course of the acoustic reflex.
The time course of the impedance changes caused by the contralateral acoustic reflex was investigated in five normal hearing, young adult subjects The acoustic reflex function was measured with equipment having a time constant of 15 milliseconds which permitted precise temporal measures. Temporal intervals from signal onset and termination to various portions of the acoustic reflex function wer...
متن کاملCerebellar interaction with the acoustic reflex.
The involvement of the cerebellar vermis in the acoustic reflex was analyzed in 12 cats, decerebrated or in pentobarbital anesthesia. Anatomical data suggested the existence of a connection of lobules VIII with the ventral cochlear nucleus. Single cell recording and evoked potential techniques demonstrated the existence of the acoustic projection to lobulus VIII. Electrical stimulation of this ...
متن کاملEffect of Contralateral Noise on Acoustic Reflex Latency Measures.
OBJECTIVE The present study was conducted to determine the effect of contralateral broadband noise on acoustic reflex latency (ARL). MATERIALS AND METHODS Acoustic reflex latency changes for 10 and 90% on- and off-time acoustic reflexes with contralateral broadband noise were measured in 30 adults with normal hearing. RESULTS The results of the study demonstrate that there was a latency pro...
متن کاملHigh levels of sound pressure: acoustic reflex thresholds and auditory complaints of workers with noise exposure.
INTRODUCTION The clinical evaluation of subjects with occupational noise exposure has been difficult due to the discrepancy between auditory complaints and auditory test results. This study aimed to evaluate the contralateral acoustic reflex thresholds of workers exposed to high levels of noise, and to compare these results to the subjects' auditory complaints. METHODS This clinical retrospec...
