Sixty-nine patients who had neurosurgical treatment for acoustic neuroma by one of two different techniques were studied with a view to determining the incidence of postoperative epilepsy. Fourty-five patients who had larger tumours underwent a combined translabyrinthine and transtentorial neurosurgical approach. For the others with smaller neuromas a translabyrinthine method was used. Only the...
Various cochlear pathologies, such as acoustic trauma, ototoxicity and age-related degeneration, cause hearing loss. These pre-existing hearing losses can alter cochlear responses to subsequent acoustic overstimulation. So far, the knowledge on the impacts of pre-existing hearing loss caused by genetic alteration of cochlear genes is limited. Prestin is the motor protein expressed exclusively i...
Ten-day-old chicks were exposed to a pure tone (1.5 kHz) or white noise at 125 dB SPL avg. RMS for 4 to 24 hours, and were sacrificed either 10, 30 or 60 days after exposure. The basilar papillae were embedded in plastic, sectioned, and hair cells were counted at 100-micrometer intervals throughout the length of the papilla. As sound exposure duration increased, both the maximum number of hair ...
Acoustic trauma not only produces temporary and permanent hearing loss but is a common cause of chronic tinnitus. Recent work indicated a possible role for the transient receptor potential channel vanilloid subfamily type 1 (TRPV1) in modulating the effects of cochlear injury. In our research, we investigated the effects of acoustic damage on TRPV1 expression in spiral ganglion neurons of adult...
