Describes the procedure for tympanometry using a 226Hz tone

What is the first thing to do before any procedures? Wash hands :)
What history should be taken in relation to tympanometry? Any discomfort, pain or discharge - Surgery - currently being treated for ear related problems
How should they remain seated? Still! Adults can be told, Children may need to be held by a parent
Tympanometry should be preceded by... Otoscopy
What are the contraindications for tympanometry? (A things) Active infection (senior), Perforation, Outer ear defects, Acute otitis media, Pain in the ear, Foreign body, Excessive (Impacted) wax, Past surgery
Instructions Soft tip in ear and box on shoulder - few tries to get right fit - May hear low tone and feel a small change in pressure like taking off in a plane - ear may feel full - should only take a few seconds - don't need to do anything just sit still - stop at a
Procedure Find correct probe tip size and insert into ear, pointing towards tympanic membrane. May need to twist to sealPress Start and measure trace
What to do before taking probe out???? PRESS STOP!!!
What if an unexpected result is obtained? Repeat the test in it's entirety
What should be checked on the screen before commencing? Tone frequency, EAR and whether it's on manual or automatic
Normative value for pressure with unit +50 to -50 daPa although outside this range may not be pathological
Normative value for compliance with unit 0.3 - 1.6 cm3
Ear Canal volume in adults with unit 0.6 - 2.5 cm3
Ear canal volume in children with unit 0.4 - 0.9
Jerger - Liden Class A Normal tympanogram, Non pathalogical
Jerger - Liden Class As Peak is in the correct place but is abnormally shallow, Could indicate ossicular fixation or otosclerosis
Jerger - Liden Class Ad Peak is in the right place but is abnormally compliant leading to an exagerated peak, could indicate ossicular chain discontinuity or hyper compliance of the tympanic membrane
Jerger - Liden Class B with normal ECV Flat Trace with normal ear canal volume, could indicate fluid behind the tympanic membrane (OME) or very advance stages of As (can also indicate impacted wax of probe against canal wall)
Jerger - Liden Class B with abnormally high ECV flat trace with a high ear canal volume, Could indicate a perforation
Jerger - Liden Class C Peak of normal compliance but with a negative pressure in the ear canal, can indicate eustachian tube dysfunction/developing OME
Double Peaks Can indicate scarring on the tympanic membrane, Should be repeated
When describing the tympanogram what should be included? a copy of the tympanogram and numerical values for all descriptors in the journal as compared with normative values
How should the tympanogram be interpreted? in the context of other findings, such as otoscopy and PTA etc.
