🦻 Flashcards
What do you assess in direct light inspection of the ears ?
Alignment, symmetry of position of ears
Skin, color, swelling
Presence of secretion, cerumen, swelling
What do you assess in otoscope inspection ?
Skin : color, swelling, discharge
Foreign bodies
Eardrum (color, alignment), Pollitzer luminous cone, pars flaccida, malleus, incus
Presence of air bubbles, serous fluid pus, blood, sclerosis, perforated eardrum
What do you palpate in the ear ?
Swellings in : auricle, temporal bone, auricle back groove
Palpate mastoid always
Palpate auricle on indication
Technique of otoscope :
Check light and place clean specula. Start with unaffected ear.
Pull auricle slightly upward and backward to stretch auditory canal. Pull auricle flat against skin.
Insert otoscope with same hand as the ear side.
Place finger against head for support
Technique of whispered voice test :
Sit behind patient. Whisper 6 combination of number and letter in each ear
Technique of Rinne’s test :
Strike tuning fork (512). Place stem against mastoid and ask patient when they cannot hear it anymore.
Then place tuning fork 2 cm front of ear with parallel prong.
Result of Rinne’s test
Positive test = normal = best in air conduction
Negative test => conductive hearing loss
Technique of Weber’s test :
Strike tuning fork, place it at the center of patient forehead. Ask where they perceive the sound.
Sound only on one side => pathological
No sound => repeat on bridge of nose then upper teeth
Result of Weber’s test
Conductive hearing loss : on the side that hear
- physical advantage hearing by bone conduction because air conduction is filtered out.
Sensorineural hearing loss : sound heard on healthy ear, the sick ear does not ear
Technique of Tilt test - Positioning test - Dix Hallpike manoeuvre
Patient sit on examination table, leg stretched. When they lie back their head project beyond the table.
Hold head rotate it 45° to one side. Lower patient in supine position with head hanging.
Patient keep eye open focusing on the tip of your nose.
Return patient to starting position in smooth movement. Repeat on the other side.
What do you assess in the Tilt test ?
Check for nystagmus or vertigo.
Left : assess left posterior and right anterior semicircular canals
Right : assess right posterior and left anterior semicircular canal
Technique of the head impulse test HIT
Sit opposite to patient. Ask them to look at the tip of your nose. Hold patient head then rotate it 20° to the left/right then abruptly back to center.
Or do opposite.
Result of the HIT
Test vestibular ocular reflex.
Positive test : eyes follow the turn then re fixate => peripheral cause.
Abnormal ear shape ?
Abnormal alignment => disorder of mastoid / parotid gland
Cauliflower ears => trauma
Helix can develop hard nodules
Otitis externa symptoms ?
Auricle tender to touch, red, moist, swollen auditory canal
