Hello Everybody!
Let us quickly review the different curves of a tympanogram.
The following are the yypes of curves in you'll see on a tympanogram:
Type A – Normal pressure and normal compliance in normal ear.
Type As – Reduced compliance (‘s’ means stiffness leading to reduced compliance) and normal pressure.
- Seen in
- Otosclerosis or other ossicular fixation
- Tympanosclerosis
- Seen in
- Ossicular discontinuity
- Thin and lax TM
Type B – Flat or dome shaped graph i.e. reduced compliance.
Seen in case of:Serous otitis media.
Thick tympanic membrane.
Type C – Normal compliance but negative pressure due to eustachian tube obstruction.
- Seen in case of:
- Retracted tympanic membrane,
- Early stages before collection of fluid in middle ear.
Hope this was helpful.
