Radiation dose to the cochlea has been proposed as a key prognostic factor in hearing preservation following stereotactic radiosurgery (SRS) for vestibular schwannoma (VS). However, understanding of the predictive value of cochlear dose on hearing outcomes following SRS for patients with non-VS tumors of the lateral skull base (LSB) is incomplete. The authors investigated rates of hearing loss following high-dose SRS in patients with LSB non-VS lesions compared with patients with VS.

Fractionated stereotactic radiosurgery (SRS) for vestibular schwannomas (VS) has been theorized to allow for tumor control with higher rates of hearing preservation in selected patients with useful he...
To evaluate the hearing preservation (HP) in cochlear implant (CI) recipients who did not fulfill the criteria for electric acoustic stimulation (EAS).
To report residual hearing preservation outcomes in patients with low frequency hearing, after cochlear implant (CI) electrode insertion with two types of electrode arrays: one straight and other peri...
Due to the constant development of technology and medicine, the eligibility criteria for cochlear implantation (CI) are undergoing gradual expansion.
To examine the possible correlation between the loss of short-term residual hearing and vestibular function after cochlear implantation (CI).
Some candidates to cochlear implantation can have residual low frequencies hearing. The EVO electrode lead has been specifically designed to preserve this residual hearing through surgery....
The objective of the present study is to investigate the effect dexamethasone and hyaluronic acid have on hearing preservation
Tumors arising from the VIIIth Nerve (vestibulo-cochlear nerve) typically present with progressive unilateral hearing loss and tinnitus. VIIIth Nerve tumors with documented growth on seria...
The purpose of this study is to understand the speech perception in noise and in quiet and localization benefits in a laboratory setting in listeners that receive a cochlear implant in an ...
This is a prospective, 1:1 randomized controlled trial of immediate versus delayed cochlear implantation (CI) on hearing handicap, communicative function, loneliness, mental wellbeing, and...
The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.
Surgical insertion of an electronic hearing device (COCHLEAR IMPLANTS) with electrodes to the COCHLEAR NERVE in the inner ear to create sound sensation in patients with residual nerve fibers.
Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.
A spiral tube that is firmly suspended in the bony shell-shaped part of the cochlea. This ENDOLYMPH-filled cochlear duct begins at the vestibule and makes 2.5 turns around a core of spongy bone (the modiolus) thus dividing the PERILYMPH-filled spiral canal into two channels, the SCALA VESTIBULI and the SCALA TYMPANI.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
A diagnostic test is any kind of medical test performed to aid in the diagnosis or detection of disease. For example: to diagnose diseases to measure the progress or recovery from disease to confirm that a person is free from disease Clin...
