  • Perilymph - Wikipedia
    Perilymph is the fluid contained within the bony labyrinth, surrounding and protecting the membranous labyrinth; perilymph resembles extracellular fluid in composition (sodium salts are the predominant positive electrolyte) and, via the cochlear aqueduct (sometimes referred to as the "perilymphatic duct"), is in continuity with cerebrospinal fluid
  • Human ear - Endolymph, Perilymph, Hearing | Britannica
    Human ear - Endolymph, Perilymph, Hearing: The perilymph, which fills the space within the bony labyrinth surrounding the membranous labyrinth, is similar, but not identical, in composition to other extracellular fluids of the body, such as cerebrospinal fluid
  • Perilymph Fistula - Dizziness-and-Balance. com
    A perilymph fistula, or PLF, is an abnormal opening in fluid filled inner ear There are several possible places that there can be an opening-- between the the air-filled middle ear mastoid sinus, into the intracranial cavity, or into other spaces in the temporal bone
  • Perilymph Fistula - Vestibular Disorders Association
    A perilymph fistula (PLF) is a defect in the small, thin membranes that separate the air-filled middle ear and the fluid-filled inner ear The symptoms of a perilymph fistula most commonly include ear fullness, fluctuating or “sensitive” hearing, dizziness, and motion intolerance
  • Difference Between Endolymph and Perilymph - Pediaa. Com
    The main difference between endolymph and perilymph is that the endolymph is the fluid found in the membranous labyrinth whereas the perilymph is the fluid that surrounds the endolymph, located inside the bony labyrinth
  • Perilymph | Radiology Reference Article | Radiopaedia. org

  • Perilymph - an overview | ScienceDirect Topics
    Perilymph has an ionic composition similar to extracellular fluid found elsewhere in the body (i e , it is K +-poor and Na +-rich), and it fills the scalae tympani and vestibule Hearing depends on the high K + concentration in endolymph that bathes the apical membranes of sensory hair cells
  • The Fluids of the Inner Ear - Hearing Health Technology Matters
    Perilymph, the fluid we will focus on, fills the space inside the bony labyrinth surrounding the membranous labyrinth It is characterized by a higher concentration of sodium and a lower concentration of potassium
  • Fluid pathways in the inner ear - Dizziness-and-Balance. com
    Perilymph is the most directly coupled to spinal fluid -- and therefore has the highest frequency response A rough estimate of the time constant is 10 seconds Perilymph is also coupled to air via the oval and round windows
