An indicator of inferior vestibular nerve
Superior length of IAM: the distance from the superior margin of the porus to the most lateral point of the fundus in the lamina cribrosa area for the superior vestibular nerve
There is increasing evidence to suggest that the vestibular receptor hair cells in the inner ear, the vestibular nerve
which carries vestibular information to the brain, and the brainstem VNC itself, all undergo a certain amount of age-related deterioration which is variable between different individuals but which may contribute to the development of dizziness in the elderly.
3,4) Recent reviews of the histology and surgery literature have demonstrated that most schwannomas arise from the covering cells (Schwann cells) of the inferior vestibular nerve
(5,6) Schwannomas that arise from the cochlear nerve and are limited to the internal auditory canal are rare.
Vestibular evoked myogenic potential (VEMP) testing is a readily available and easily performed audiologic test used to assess saccular function and the integrity of the inferior vestibular nerve
The patient underwent a translabyrinthine excision of the lesion, which was located on a superior vestibular nerve
, extending inferiorly to the area of the cochlear modiolus.
To summarize, they are the use of the operating microscope, tympanoplasty and mastoidectomy techniques, stapes surgery, endolymphatic sac surgery for intractable Meniere's disease, skull base surgery (for example, removal of vestibular schwannomas, vestibular nerve
sections), use of intratympanic gentamycin, and cochlear implantation, not to mention the discovery of new diseases.
There should be interesting research possibilities for applying nanotechnology to some particularly challenging otolaryngologic problems, such as restoration of cochlear hair cells, regeneration of acoustic or vestibular nerve
fibers, treatment of tinnitus, and treatment of anosmia, among others.
The first reported use of the middle cranial fossa approach occurred in 1904; a hammer and chisel were used then to access the vestibular nerve
The specific procedures included 6 vestibular nerve
sections, 4 transcanal labyrinthectomies, and 2 transmastoid labyrinthectomies.
The number of these sites is significantly decreased by previous sectioning of the vestibular nerve
, indicating that glutamate is involved in the transfer of signals from vestibular afferent neurons.
Vestibular schwannomas arise from Schwann cells on branches of the vestibulocochlear nerve, most commonly the superior vestibular nerve
