Middle Ear Pressure Gain and Cochlear Input Impedance in the Chinchilla
Measurements of middle ear conducted sound pressure in the cochlear vestibule PV have been performed in only a few individuals from a few mammalian species. Simultaneous measurements of sound-induced stapes velocity VS are even more rare. We report simultaneous measurements of VS and PV in chinchillas. The VS measurements were performed using single-beam laser-Doppler vibrometry; PV was measure...
متن کاملNon-invasive estimation of middle-ear input impedance and efficiency.
A method to transform the impedance measured in the ear canal, ZEC, to the plane of the eardrum, ZED, is described. The portion of the canal between the probe and eardrum was modeled as a concatenated series of conical segments, allowing for spatial variations in its cross-sectional area. A model of the middle ear (ME) and cochlea terminated the ear-canal model, which permitted estimation of ME...
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 کاملOtotoxic Effects of Middle Ear Gentamicin Instillation in the Chinchilla
Gentamicin sulphate is used clinically to produce vestibular organ damage in patients with intractable vertigo. The drug is given locally by middle ear instillation. In humans, gentamicin appears to have a more toxic effect on the vestibular parts of the inner ear than on the cochlea. However, cochlear effects are not insignificant and to further explore the utility of monitoring vestibular and...
متن کاملBacterial otitis media, the chinchilla middle ear, and biofilms.
Otitis media in children has a significant impact on heath care and health-care economics [1]. It is the number one reason children are seen in physicians’ offices and the most common reason children are given antibiotics [2]. The economic impact was estimated in 1998 to be between $3 billion and $5 billion per year in the United States. This estimate does not take into consideration the indire...
