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.

New non‐contrast MRI of endolymphatic hydrops in Ménière's disease considering inversion time

Laryngoscope Investigative Otolaryngology
Objectives Three‐tesla MRI with gadolinium‐based contrast agents is important in diagnosing Ménière's disease. However, contrast agents cannot be used in some patients.

An LCMS-based untargeted metabolomics protocol for cochlear perilymph : highlighting metabolic effects of hydrogen gas on the inner ear of noise exposed Guinea pigs

, 2019
Introduction Noise-induced hearing loss (NIHL) is an increasing problem in society and accounts for a third of all cases of acquired hearing loss. NIHL is caused by formation of reactive oxygen species (ROS) in the cochlea causing oxidative stress ...

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

Perilymph fistula.

Ear, nose, & throat journal, 1989
PLF is an enigmatic otologic disease that may be congenital or acquired through surgery, trauma, neoplasm, or infection. The exact incidence of PLF is unknown, primarily because it is difficult to diagnose. A careful, thorough history is important in recognizing PLF.

Use of TissuePatchDural™ in the closure of an iatrogenic fistula following posterior semicircular canal occlusion surgery for intractable benign paroxysmal positional vertigo

Journal of Surgical Case Reports, 2010
Benign paroxysmal positional vertigo (BPPV) is a common disorder caused by the dislocation of otoconia most commonly into the posterior canal. The primary symptoms are brief episodes of head-position related vertigo which may be accompanied by nausea and
