the fluid contained within the space separating the membranous labyrinth from the osseous labyrinth; it is entirely separate from the endolymph.

per·i·lymph

(per'i-limf), [TA]
The fluid contained within the osseus labyrinth, surrounding and protecting the membranous labyrinth; perilymph resembles extracellular fluid in composition (sodium salts are the predominant positive electrolyte) and, through the perilymphatic duct, is in continuity with cerebrospinal fluid.

perilymph

/peri·lymph/ (per´ĭ-limf) the fluid within the space separating the membranous and osseous labyrinths of the ear.

the clear fluid separating the osseous labyrinth from the membranous labyrinth in the internal ear. Compare endolymph.

per·i·lymph

(per'i-limf) [TA]
The fluid contained within the osseous labyrinth, surrounding and protecting the membranous labyrinth; perilymph resembles extracellular fluid in composition (sodium is the predominant cation) and, via the perilymphatic duct, is in continuity with cerebrospinal fluid.

One possibility for providing a close apposition is to promote the growth of neurites from the ganglion cells toward the electrodes in the ST with controlled delivery of neurotrophic drugs into the perilymph [89-92].
The protein can also be demonstrated in human aqueous humor [4] and in perilymph fluid [5-7].
We also took into account the effects of perilymph fistula (PLF) on the etiology of sudden hearing loss and postoperative outcomes.
10) In an effort to correlate changes in CSF pressure with perilymph pressure, Carlborg et al performed experiments in cats with open and artificially disrupted cochlear aqueducts.
For example, guinea pigs have a patent cochlear aqueduct, and this can lead to CSF contamination during perilymph sampling.
5,6) These studies demonstrated round window permeability, with measurable levels of drug in the perilymph.
7) In our patient, no perilymph gusher was observed from the windows or from any other site in the middle ear, even after the extensive disease was cleared from the area.
Middle ear or mastoid procedures were used to treat persistent perforations, ossicular discontinuity, chronic otitis media with or without cholesteatoma, and perilymph fistula.
9) The transtympanic endoscope has been used for quite some time for the diagnosis of perilymph fistula and other middle ear disorders.
Perilymph fistulae are difficult to diagnose because they present with a wide variety of signs and symptoms, they are associated with many etiologies, and they often mimic other conditions.
Perilymph gusher (PG) is a very rare occurrence that can lead to an adverse outcome during inner ear surgery.
