Inner ear contribution to bone conduction hearing in the human.
Bone conduction (BC) hearing relies on sound vibration transmission in the skull bone. Several clinical findings indicate that in the human, the skull vibration of the inner ear dominates the response for BC sound. Two phenomena transform the vibrations of the skull surrounding the inner ear to an excitation of the basilar membrane, (1) inertia of the inner ear fluid and (2) compression and exp...
متن کاملMiddle ear and inner ear effects on clinical bone-conduction threshold.
The measurement of bone-conduction thresholds is an integral part of audiologic evaluation. The relationship between bone-conduction and air-conduction thresholds is the differentiating diagnostic indicator between conductive and sensorineural hearing loss. At the same time, the influence of middle ear and inner ear structures upon the bone-conduction response has been well documented. We prese...
متن کاملRole of Middle-Ear Inertial Component of Bone Conduction in Chinchilla
Bone conduction describes the mechanisms that produce a hearing sensation when the skull bones are subjected to vibration. Multiple components and pathways have been suggested to contribute to total bone-conducted sound. They include outer-ear cartilaginous wall compression, middle-ear inertia, fluid inertia, cochlear capsule compression and soft-tissue conduction. Due to the complexity of the ...
متن کاملInner ear disturbances related to middle ear inflammation
The inner and middle ear are connected mainly through round and oval windows, and inflammation in the middle ear cavity can spread into the inner ear, which might induce a disturbance. In cases with intractable otitis media, attention should also be paid to symptoms related to the inner ear. In this paper, middle ear inflammation and related inner ear disturbances are reviewed with a focus on r...
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...
