Immediately following the event, blood flow and therefore oxygen transport is reduced locally, leading to hypoxia of the cells near the location of the original insult.AudiometryCerebral blood flow: Cerebral blood flow (CBF) is the blood supply to the brain in a given period of time.Tolias C and Sgouros S.Ceruminous gland: Ceruminous glands are specialized sudoriferous glands (sweat glands) located subcutaneously in the external auditory canal. Ceruminous glands are simple, coiled, tubular glands made up of an inner secretory layer of cells and an outer myoepithelial layer of cells.Crandall syndrome: Crandall syndrome is a very rare congenital disorder characterised by progressive sensorineural hearing loss, hair loss associated with pili torti, and hypogonadism demonstrated through low levels of luteinising hormone and growth hormone. It is thought to be an autosomal recessive disorder closely related to Björnstad syndrome which presents similarly but without hypogonadism.TympanoplastyOtitis externaFrequency following response: Frequency following response (FFR), also referred to as Frequency Following Potential (FFP), is an evoked potential generated by periodic or nearly-periodic auditory stimuli.Burkard, R.SoundBite Hearing System: SoundBite Hearing System is a non-surgical bone conduction prosthetic device that transmits sound via the teeth. It is an alternative to surgical bone conduction prosthetic devices, which require surgical implantation into the skull to conduct sound.Otolith: An otolith (οτο-, oto-, ear + λιθος, lithos, a stone), also called statoconium or otoconium, is a structure in the saccule or utricle of the inner ear, specifically in the vestibular labyrinth of vertebrates. They have been identified in both extinct and extant vertebrates.Vestibular system: The vestibular system, in most mammals, is the sensory system that provides the leading contribution about the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals, situated in the vestibulum in the inner ear (Figure 1).Prelingual deafness: A prelingual deaf individual is someone who was born with a hearing loss, or whose hearing loss occurred before they began to speak. Infants usually start saying their first words around one year.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingStapedius muscleNachzehrer: A nachzehrer is a sort of German vampire. Nachzehrer translates "after (nach) living off (zehre)" likely alluding to their living after death or living off humans after death in addition to the choice of "nach" for "after" which is similar to "nacht" ("night").Large ornamented Ediacaran microfossil: Large ornamented Ediacaran microfossils (LOEMs) are microscopic acritarchs, usually over 100 μm in diameter, which are common in sediments of the Ediacaran period, . They largely disappear from the Ediacaran fossil record before , roughly coeval with the origin of the Ediacara biota.Godflesh discography: The following is a comprehensive discography of Godflesh, an English industrial metal band.Indian Genetic Disease DatabaseSpiral pumpHyperintensitySound changeOtitis media: suppurativePerilymph: Perilymph (also known as Cotunnius' liquid, and liquor cotunnii) is an extracellular fluid located within the cochlea (part of the inner ear) in two of its three compartments: the scala tympani and scala vestibuli. The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid.Gross pathology: Gross pathology refers to macroscopic manifestations of disease in organs, tissues, and body cavities.
