• Ear and Hearing Conditions

Medical conditions affecting the ears or the hearing systems.



• Ear Bleeding

Bleeding from the ear - usually occurs due to trauma to the ear.



• Ear Canal

The funnel shape opening that enables ear to hear sound. A component of the outer ear that leads to the tympanic membrane (eardrum) of the middle ear. The ear canal is lined with wax and hairs that prevent small foreign material from traveling deeper into the ear.



• Ear Drum

Separates outer ear from inner, vibrates like drum when sound strikes it



• Ear Foreign Body

Having a "foreign body" stuck inside the ear



• Ear Infection (infant)

An infection that affects the ear



• Ear Pain

Pain due to lesions related to the external ear or radiating pain from middle and inner ear.



• Earwax

Buildup of wax (cerumen) inside the ear canal



• Electrocochleography (ECoG)

This test provides objective information about the auditory system at the level of the inner ear. This is a simple and non-invasive test for the patient. Electrodes are placed on the head and foam plugs in the ear canals. A click stimulus will be presented through the foam plugs. The test will record brain waves in response to the stimulus. The audiologist will complete the analysis and interpretation of the test and your Otolaryngologist will discuss the test results with you.



• Electroneuronography (ENoG)

This test involves electrical stimulation of the facial nerve in patients with sudden onset of facial paralysis to determine their prognosis of recovery from the paralysis.



• Electronystagmography (ENG)

This test provides objective information about the condition of the vestibular (balance) portion of the inner ear. This test comprises of subtests that have the patient look at different visual stimuli, lie in different positions and introduce cool and warm water to the ears. The audiologist is looking for an eye movement called nystagmus and will measure the eye movement as part of a larger reflex, the vestibulo-ocular reflex that helps determine the condition of the inner ear.



• Endolymph

A fluid in the labyrinth, the organ of balance in the inner ear.



• Eustachian Tube

A small tube that connects the middle ear with the back of the throat. It allows the air in the middle ear to be refreshed periodically.



• Eustachian Tube Disorders

Any disorder that affects the Eustachian tubes of the ear



• Eustachian Tube Dysfunction

Failure of the eustachian tube to open, resulting in a "plugged" feeling in the ear and possibly a buildup or negative pressure in the middle ear.



• Exchange Rate

The rate in which sound energy is averaged over time. Utilizing a decibel scale, every time the sound energy doubles, the measured level increases by 3 dB. This is the 3 dB exchange rate that most of the world uses.



• External Ear

Consists of the Pinna or the visible portion of the ear and the external auditory canal.
