The cartilage-conduction pathway was recently proposed as a third auditory pathway; however, middle-ear vibrations have not yet been investigated in vivo. We aimed to measure the ossicles and bone vibration upon stimulation with non-contact laser Doppler vibrometer. recruited adult patients normal ear structures who underwent cochlear implant surgery at our hospital between April 2020 December ...

Ossicular repositioning and ossicular prostheses are said to offer an oppotunity to preserve the air space of the middle ear and improve the transmission of sound to the stape footplate. Depending upon the pathological circumstances, any convenient remaining portion of the auditory ossicles may be used to reconstruct a functioning ossicular chain. But the problem of reconstruction is not simple...

The effect of 0.3% otic solution of ofloxacin on the cartilages constituting the epiphyses of the auditory ossicles and the wall of the auditory tube was histologically examined after 30-day repeated intratympanic administration to juvenile male guinea pigs aged 4 weeks. Ofloxacin showed no chondrotoxicity for the cartilages and, in some but not all animals, reduced haemorrhage and neutrophil i...

This study is based on the examination of histological sections of specimens of different ages and of adult ossicles from macerated skulls representing a wide range of taxa and aims at addressing several issues concerning the evolution of the ear ossicles in marsupials. Three-dimensional reconstructions of the ear ossicles based on histological series were done for one or more stages of Monodel...

Introduction The human auditory system includes the hearing and balance organs, and can be divided into three main elements: outer ear, middle ear and inner ear. The auditory ossicles are three very small bones: the malleus, incus and stapes, confined in the middle ear and coupled in chain. Their main function is to transmit sound energy from the tympanic membrane to the fluid-filled cochlea. A...

Fish Ear Hearing SwimbIadder Weberian ossicles Thresholds Behavior Eighth nerve Auditory Sound localization Discrimination Review Abstract The literature on fish hearing has increased significantly since our last critical review in 1973. The purpose of the current paper is to review the more recent literature and to identify those questions that need to be asked to develop a fuller understandin...
