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 کاملValidity of the ipsilateral acoustic reflex as a screening parameter.
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 that the inclusion of the IAR resulte...
متن کاملبررسی ارتباط بین حساسیت صوتی سیستم دهلیزی و توانایی تشدید رفلکس عضلانی برانگیخته صوتی گوش میانی در بزرگسالان دارای شنوایی طبیعی
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 کاملAuditory brainstem circuits that mediate the middle ear muscle reflex.
The middle ear muscle (MEM) reflex is one of two major descending systems to the auditory periphery. There are two middle ear muscles (MEMs): the stapedius and the tensor tympani. In man, the stapedius contracts in response to intense low frequency acoustic stimuli, exerting forces perpendicular to the stapes superstructure, increasing middle ear impedance and attenuating the intensity of sound...
متن کاملAcoustic stimulation of the ear of the goldfish (Carassius auratus).
Microphonic potentials were recorded from the ears of the goldfish during acoustic stimulation in a situation where sound pressure and particle displacement could be varied. Microphonic potentials from fishes with the swim bladder intact were proportional to sound pressure. After removal of the swim bladder, sound pressure sensitivity declined by 20-35 dB and the response was generated in propo...
