Introduction: Sensorineural hearing loss (SNHL) is one of the possible complications of radiotherapy treatment of brain tumors. The auditory system of patients with brain tumors often is placed inside of radiation field and receives a significant amount of radiation dose resulting in hearing loss. The purpose of this study was to compare contouring and delivery dose to cochlea...

introduction:visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. optical coherence tomography (oct) is a high-resolution imaging technology which may be used for the visualization of tissues. in this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.materials and methods:thr...

Cochlea implant fitting is based on ECAP measurements (electrically evoked sum action potentials). It claimed that profiles differ depending the electrode array and its position as well time of deafening patient age. Retrospectively, Auto NRT (Neutral Response Telemetry) data from 812 patients who had received a cochlea between 11/05 11/21 were evaluated. The intraoperative children adults was ...

A bone conduction (BC) sound presented on either side of the head will travel to cochleae in both ears, and this crosstalk phenomenon is considered one factor limiting benefits binaural hearing with BC. Previous studies have demonstrated feasibility measuring phase level required for cancellation at cochlea; however, given a human subject’s inability consistently detect low frequencies, ...

Abstract The inner ear, or cochlea, is a fluid-filled organ housing the mechanosensitive hair cells. Sound stimulation relayed to cells through waves that propagate on elastic basilar membrane. Sensorineural hearing loss occurs from damage and cannot currently be cured. Although drugs have been proposed prevent restore functionality cells, difficulty with such treatments ensuring adequate drug ...

Introduction: The purpose of this study was to develop a statistical model for prediction of radiation induced sensorineural hearing loss (SNHL) induced by radiotherapy in patients with brain tumors.   Materials and Methods: CT scan of 18 patients (10 males and 8 females) with brain tumor who were referred to Radiation Center of Milad Hospital in Isfahan in 2...

OBJECTIVE Administration of an aminoglycoside antibiotic and loop diuretic causes damage to hair cells in the organ of Corti, resulting in their death and the death of their corresponding spiral ganglion neurons. While this phenomenon has been studied previously, analysis of its effects in the whole cochlea has not been reported. The authors sought to evaluate the effects of a combination dose ...

The cochlea plays a crucial role in mammal hearing. The basic function of the cochlea is to map sounds of different frequencies onto corresponding characteristic positions on the basilar membrane (BM). Sounds enter the fluid-filled cochlea and cause deflection of the BM due to pressure differences between the cochlear fluid chambers. These deflections travel along the cochlea, increasing in amp...
