Estimation of Stapedius-Muscle Activation using Ear Canal Absorbance Measurements
The stapedius muscle, which is located in the middle ear, goes into contraction when the ear is exposed to high sound intensities. This muscle activation is called 'the acoustic reflex'. Measurement of the acoustic reflex is clinically of importance since it can reveal diagnostic information about the middle ear's pathologies. Moreover, this muscle-activation alters the acoustic characteristics...
متن کاملThe Effect of Ethnicity on Wideband Absorbance of Neonates with Healthy Middle Ear Functions in Malaysia: A Preliminary Study
BACKGROUND AND OBJECTIVES Although ethnicity effect on wideband absorbance (WBA) findings was evident for adults, its effect on neonates has not been established yet. This study aimed to investigate the influence of ethnicity on WBA measured at 0 daPa from neonates with healthy middle ear functions. SUBJECTS AND METHODS Participants were 99 normal, healthy, full-term newborn babies with chron...
متن کاملWideband middle ear power measurement in infants and children.
Wideband middle ear power (WMEP) measurement is a method of middle ear analysis that may provide improved diagnostic capability over single-frequency tympanometry. However, normative data, information about test-retest reliability, and results in clinical disorders are needed for clinical application. Normative and reliability data on WMEP in children three days to 47 months of age were obtaine...
متن کاملAllergy and recurrent middle ear effusion
Objectives: The aim of this study was to compare the otitis media with effusion (OME) groups that improved when treated with adenoidectomy and Ventilation Tube (VT), to the group of the recurred after surgery and detect the possible role of allergy in OME. Material and Methods: This study was performed on two groups. The Patient group consisted of 38 patients with recurrent OME with allergy an...
متن کاملGain and maximum output of two electromagnetic middle ear implants: are real ear measurements helpful?
We compared the output of two electronic middle ear implants: the Otologics MET device and the Vibrant Soundbridge device. Both devices were programmed in the linear amplification mode. Aided minus unaided sound pressure levels recorded in the ear canal (objective gain) were compared to unaided minus aided soundfield thresholds (functional gain) in 13 patients with severe sensorineural hearing ...
