Endolymphatic hydrops is a disorder of the inner ear. It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.
Objective identification and monitoring of Ménière's disease and endolymphatic hydrops (EH) Intraoperative monitoring of auditory system function during surgery on the brainstem or cerebellum; Enhancement of Wave I of the auditory brainstem response, particularly in patients who are hard of hearing [2] Diagnosis of auditory neuropathy
Cochlear hydrops (or cochlear Meniere's or cochlear endolymphatic hydrops) is a condition of the inner ear involving a pathological increase of fluid affecting the cochlea. This results in swelling that can lead to hearing loss or changes in hearing perception. It is a form of endolymphatic hydrops and related to Ménière's disease. Cochlear ...
More than 85% of patients with Ménière's disease get better from changes in lifestyle, medical treatment, or minimally invasive surgical procedures. Those procedures include intratympanic steroid therapy, intratympanic gentamicin therapy or endolymphatic sac surgery. [18]
Perilymph and endolymph have unique ionic compositions suited to their functions in regulating electrochemical impulses of hair cells. The electric potential of endolymph is ~80-90 mV more positive than perilymph due to a higher concentration of K compared to Na. [3]
After Melanie Duquette, 70, had extensive back surgery earlier this year, her doctor sent her to a rehab center to recover since it wasn’t safe for her to be home alone. But after six weeks, her ...
Doctors and specialists at the Murdoch Children's Research Institute in Melbourne, Australia, are studying and reprogramming the potential of the blood to treat heart failure in children.
From the posterior wall of the saccule a canal, the endolymphatic duct, is given off; this duct is joined by the utriculosaccular duct, and then passes along the vestibular aqueduct and ends in a blind pouch, the endolymphatic sac, on the posterior surface of the petrous portion of the temporal bone, where it is in contact with the dura mater.
