Unilateral sensorineural hearing loss is a common symptom of vestibular schwannomas in adolescent patients with neurofibromatosis type 2 or sporadic vestibular schwannomas and is often the initial clinical feature. While rare cases of sensorineural impairment presenting as vision or hearing loss due to metastatic medulloblastoma are known, hearing loss as an isolated presenting symptom of primary malignant neuroepithelial tumors of the central nervous system has not been reported in the pediatric population so far. We present two adolescents with unilateral hearing loss due to cochlear nerve dysfunction as the only symptom of a primary nonmetastatic medulloblastoma of the WNT signaling pathway family members subgroup.

Vestibular schwannoma (VS) is a benign intracranial neoplasm originating in the Schwann cells of the vestibular nerve. Despite its origin, the most common symptom is sensorineural hearing loss which i...
The etiology of sensorineural hearing loss (SNHL) in patients with jugular paraganglioma (JP) whose tumors lack inner ear fistulae or vestibulocochlear nerve involvement is unknown. Recent literature ...
Purpose The aims of this study were to (a) determine if a high-quality adaptation of an audiovisual nonword repetition task can be completed by children with wide-ranging hearing abilities and to (b) ...
The most common complaint of patients affected by chemotherapy-induced hearing loss is difficulty understanding speech in noisy environments despite the use of hearing aids. Cochlear dead regions, tho...
Purpose This forum provides an overview of current research and clinical practice for children with mild bilateral or unilateral hearing loss. Historically, there has been ambiguity surrounding the ne...
This feasibility study evaluates whether children with unilateral, moderate to profound sensorineural hearing loss experience an improvement in speech perception, hearing in noise, localiz...
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 ...
Bilateral severe to profound hearing loss is a socially disabling handicap. Cochlear implants can be used to improve hearing in cases where conventional hearing aids are not effective. The...
The majority of studies about bimodal hearing advantages have been conducted on adults but scant relevant studies into pediatric users, therefore more comparative studies are required to c...
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...
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.
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.
Pathological processes of the VESTIBULOCOCHLEAR NERVE, including the branches of COCHLEAR NERVE and VESTIBULAR NERVE. Common examples are VESTIBULAR NEURITIS, cochlear neuritis, and ACOUSTIC NEUROMA. Clinical signs are varying degree of HEARING LOSS; VERTIGO; and TINNITUS.
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.
The 8th cranial nerve. The vestibulocochlear nerve has a cochlear part (COCHLEAR NERVE) which is concerned with hearing and a vestibular part (VESTIBULAR NERVE) which mediates the sense of balance and head position. The fibers of the cochlear nerve originate from neurons of the SPIRAL GANGLION and project to the cochlear nuclei (COCHLEAR NUCLEUS). The fibers of the vestibular nerve arise from neurons of Scarpa's ganglion and project to the VESTIBULAR NUCLEI.
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...
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
