| Hearing impairment A hearing impairment or deafness is a full or partial decrease in the ability to detect or understand sounds. Deaf culture, they prefer the terms Deaf and Hard of Hearing.Sound waves vary in amplitude and in frequency. Amplitude is the sound wave's peak pressure variation. Frequency is the number of cycles per second of a sinusoidal component of a sound wave. Loss of the ability to detect some frequencies, or to detect low-amplitude sounds that an organism naturally detects, is a hearing impairment. Hearing_impairment | |
| Ménière's disease Ménière's disease () is a disorder of the inner ear that can affect hearing and balance. It is characterized by episodes of dizziness and tinnitus and progressive hearing loss, usually in one ear. It is caused by an increase in volume and pressure of the endolymph of the inner ear. It is named after the French physician Prosper Ménière, who first reported that vertigo was caused by inner ear disorders in an article published in 1861. Ménière's_disease | |
| Tinnitus Tinnitus ( or , from the Latin word tinnītus meaning "ringing") is the perception of sound within the human ear in the absence of corresponding external sound.Tinnitus can be perceived in one or both ears or in the head. It is usually described as a ringing noise, but in some patients it takes the form of a high pitched whining, buzzing, hissing, screaming, humming, tinging or whistling sound, or as ticking, clicking, roaring, "crickets" or "tree frogs" or "locusts", tunes, songs, or beeping.

| Arnold-Chiari malformation Arnold-Chiari malformation is a malformation of the brain. It consists of a downward displacement of the cerebellar tonsils and the medulla through the foramen magnum, sometimes causing hydrocephalus as a result of obstruction of cerebrospinal fluid (CSF) outflow . The cerebrospinal fluid outflow being caused by phase difference in outflow and influx of blood in the vasculature of the brain. Arnold-Chiari_malformation | |
| Fistula In medicine, a fistula (pl. fistulas or fistulae) is an abnormal connection or passageway between two epithelium-lined organs or vessels that normally do not connect. Fistula | |
| Otosclerosis Otosclerosis is an abnormal growth of bone of the middle ear which can result in hearing loss. Otosclerosis | |
| Earwax Earwax, also known by the medical term cerumen, is a yellowish waxy substance secreted in the ear canal of humans and many other mammals. It protects the skin of the human ear canal, assists in cleaning and lubrication, and also provides some protection from bacteria, fungi, insects and water. Excess or impacted cerumen can press against the eardrum and/or occlude the external auditory canal and impair hearing. Earwax | |
| Barotrauma Barotrauma is physical damage to body tissues caused by a difference in pressure between an air space inside or beside the body and the surrounding gas or liquid.Barotrauma typically occurs to air spaces within a body when that body moves to or from a higher pressure environment, such as when a SCUBA diver, a free-diving diver or an airplane passenger ascends or descends, or during uncontrolled decompression of a pressure vessel. Barotrauma | |
| Hearing aid A hearing aid is an electroacoustic body worn apparatus which typically fits in or behind the wearer's ear, and is designed to amplify and modulate sounds for the wearer. Earlier devices, known as an "ear trumpet" or "ear horn", were passive funnel-like amplification cones designed to gather sound energy and direct it into the ear canal. Similar devices include the bone anchored hearing aid, and cochlear implant. Hearing_aid | |
| Hearing test hearing test provides an evaluation of the sensitivity of a person's sense of hearing and is most often performed by an audiologist using an audiometer. An audiometer is used to determine a person's hearing sensitivity at different frequencies. There are other hearing tests as well, e.g. Weber test and Rinne test. Hearing_test | |
| Acoustic neuroma An acoustic neuroma, also called a vestibular schwannoma, is a benign primary intracranial tumor of the myelin-forming cells of the vestibulocochlear nerve (CN VIII). (Neuroma is derived from Greek, meaning "nerve tumor".) The term "acoustic" is a misnomer, as the tumor rarely arises from the acoustic (or cochlear) division of the vestibulocochlear nerve.

| Glomus tumor Glomus tumor was also the name formerly used for a tumor now called a paraganglioma.A glomus tumor (also known as glomangioma, or nonchromaffin paraganglioma) is a rare benign neoplasm, is a specialized arteriovenous anastomosis usually found in the skin of the extremities. It arises from the glomus body, and was first described at Mount Sinai Hospital in New York City. Glomus_tumor | |

| Cogan syndrome Cogan syndrome is a rare disorder characterized by recurrent inflammation of the front of the eye (the cornea) and often fever, fatigue, and weight loss, episodes of dizziness, and hearing loss. It can lead to deafness or blindness if untreated. The classic form of the disease was first described by D.G. Cogan in 1945. Cogan_syndrome | |

| Tullio phenomenon Tullio phenomenon, sound-induced vertigo, dizziness, nausea and/or eye movements (nystagmus) was first described in 1929 by the Italian biologist Prof. Pietro Tullio. (1881-1941) During his experiments on pigeons, Tullio discovered that by drilling tiny holes in the semicircular canals of his subjects, he could subsequently cause them balance problems when exposed to sound.The cause is usually a fistula in the middle or inner ear, allowing abnormal sound-synchronized pressure changes in the balance organs.

| Vitamin B12 deficiency B12 deficiency is a reduction in vitamin B12 from inadequate dietary intake or impaired absorption. The condition is commonly asymptomatic, but can also present as anemia characterized by enlarged blood corpuscles, so-called megaloblastic anemia. subacute combined degeneration of spinal cord.The anemia is thought to be due to problems in DNA synthesis, specifically in the synthesis of thymine, which is dependent on products of the MTR reaction.

| Autoimmune inner ear disease Autoimmune inner ear disease is a suspected autoimmune disease characterized by rapidly progressive bilateral sensorineural hearing loss. It occurs when the body's immune system attacks cells in the inner ear that are mistaken for a virus or bacteria. Autoimmune inner ear disease was first described by Dr. Brian McCabe of the University of Iowa in 1979. Autoimmune_inner_ear_disease |
