The ear canal volume indicates whether a perforation in the eardrum (tympanic membrane) may be present. The middle ear pressure indicates whether any fluid is present in the middle ear space (also called "glue ear" or "otitis media with effusion"). Compliance measurement indicates how well the eardrum and ossicles (the three ear bones) are moving.
A normal tympanogram (left) is labelled Type A. There is a normal pressure in the middle ear with normal mobility of the eardrum and ossicles. Type B tympanogram may reveal (a) fluid in the middle ear, (b) perforation of the tympanic membrane or patent pressure equalization tube, or (c) a tumor in the middle ear.
Eyes: eye examination and acuity (including ophthalmoscope) Ears: hearing examination and evaluation of tympanic membrane (TM) ( otoscope used in evaluation of ears, nose, and mouth) A neurological examination is usually considered separate from the HEENT evaluation, although there can be some overlap in some cases.
Both eyes will turn toward the contralateral ear, with horizontal nystagmus (quick horizontal eye movements) to the ipsilateral ear. If the water is cold, relative to body temperature (30 °C or below), the endolymph falls within the semicircular canal, decreasing the rate of vestibular afferent firing.
The distal (front) end of the otoscope has an attachment for disposable plastic ear specula. The examiner first pulls on the pinna (usually the earlobe, side or top) to straighten the ear canal, and then inserts the ear speculum side of the otoscope into the outer ear. It is important to brace the index or little finger of the hand holding the ...
Mixed hearing loss is a combination of conductive and sensorineural hearing loss. Chronic ear infection (a fairly common diagnosis) can cause a defective ear drum or middle-ear ossicle damages, or both. In addition to the conductive loss, a sensory component may be present. Central auditory processing disorder
It is caused by the fact that even though one ear is unable to respond to the test, the other ear can still be stimulated by the bone conduction test (via conducting sound through skull bones to the opposite ear), causing the patient to respond to the tuning fork on mastoid but not when it's placed near the affected ear's air canal. [5]
The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
