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 ...
After an otoscopy (examination of the ear with an otoscope) to ensure that the path to the eardrum is clear and there is no perforation, the test is performed by inserting the tympanometer probe in the ear canal. The instrument changes the pressure in the ear, generates a pure tone, and measures the eardrum responses to the sound at different ...
-do-; long blades ( uses: in operations such as Submucous Resection of the nasal septum) •Killian's long bladed nasal speculum-do-; long blades and with handles; used more operations like SMR & Septoplasty. ( advantage: blade can be adjusted and fixed with screws, to avoid strain due to holding ) •Lempert's endaural speculum
Ear examination [ edit ] Prior to the hearing test, the ears of the patient are usually examined with an otoscope to make sure they are free of wax, that the eardrum is intact, the ears are not infected, and the middle ear is free of fluid (indicating middle ear infection).
The diagnosis may be missed in most early cases because the examination of the ear, with the exception of pain with manipulation, is nearly normal. In some early cases, the most striking visual finding is the lack of earwax. As a moderate or severe case of external otitis resolves, weeks may be required before the ear canal again shows a normal ...
A man performs the Valsalva maneuver while his ear is examined with an otoscope. [ edit on Wikidata ] The Valsalva maneuver is performed by a forceful attempt of exhalation against a closed airway, usually done by closing one's mouth and pinching one's nose shut while expelling air, as if blowing up a balloon.
Electronystagmography (ENG) uses skin electrodes and an electronic recording device to measure nystagmus evoked by procedures such as caloric stimulation of the ear Acoustic immittance audiometry - Immittance audiometry is an objective technique which evaluates middle ear function by three procedures: static immittance, tympanometry, and the ...
A case history (usually a written form, with questionnaire) can provide valuable information about the context of the hearing loss, and indicate what kind of diagnostic procedures to employ. Case history will include such items as: major concern; birth and pregnancy information; medical history; development history; family history; workplace ...
