Suspicion and Treatment of Perilymphatic Fistula: A Prospective Clinical Study

Audiology Research
Background: Since the discovery of the perilymphatic fistula (PLF), the diagnosis and treatment remain controversial. If successfully recognized, the PLF is surgically repairable with an obliteration of the fistula site.

Understanding the cochlear implant environment by mapping perilymph proteomes from different species

, 2016
Cochlear implants operate within a bony channel of the cochlea, bathed in a fluid known as the perilymph. The perilymph is a complex fluid containing ions and proteins, which are known to actively interact with metallic electrodes.

Refined circular autopsy saw design and standardized technique for postmortem human temporal bone procurement and perilymph collection

Frontiers in Neuroscience
Postmortem human temporal bones provide an irreplaceable resource for studying the cochlea and vestibular labyrinth in their native anatomic context, as the tissues of these organs cannot be non-destructively biopsied.

Protein profile of mouse endolymph suggests a role in controlling cochlear homeostasis

iScience
Summary: The cochlea contains two extracellular fluids, perilymph and endolymph. Endolymph exhibits high potential of approximately +80 to +110 mV (depending on species), which sensitizes sensory hair cells.

Frequency of Herpes Simplex Virus Types 1 and 2 and Cytomegalovirus in Perilymph and Peripheral Blood Samples of Cochlear-Implanted Children Using the Polymerase Chain Reaction Method

Auditory and Vestibular Research
Background and Aim: Inner ear infection with some viruses may be one of the possible causes of Sensorineural Hearing Loss (SNHL). This study aims to determine the frequency of Herpes Simplex Virus 1 and 2 (HSV-1, HSV-2) and Cytomegalovirus (CMV) in ...

Effect of Intracochlear Brain-Derived Neurotrophic Factor on Guinea Pig Sensorineural Hearing Loss

Journal of Otolaryngology - Head and Neck Surgery
Importance This study investigates the potential of brain-derived neurotrophic factor (BDNF) as treatment for sensorineural hearing loss (SNHL) in a guinea pig model to potentially advance hearing restoration strategies. The correlation between oxidation-

In Vivo Effects of Reduced-Sodium Perilymph Perfusion on Hair Cell and Neural Potentials [PDF]

, 2007
To determine the functional significance of the sodium-transport mechanisms of the outer hair cells (OHCs) in vivo, the effect of reduced perilymphatic sodium on cochlear potentials was investigated in the guinea pig by perfusion of scala tympani with

Suppression of Post-Caloric Nystagmus in Experimental Perilymph Fistula

, 2009
Albino guinea pigs (n=28) were used to establish an animal model of the perilymph fistula (PLF) by suctioning 2-4 wl of perilymph via the left round window membrane.
