Tympanometry gives you 5 types of tympanogram
Type A
Type As
Type Ad
Type B
Type C
Now I used get confused that which type of tympanogram is found in which condition
So here is a mnemonic
Type As is seen in otosclerosis.. how I remember this is remember that s for sclerosis so type As is seen in Sclerosis(otosclerosis)...
Type Ad is seen in Disruption (ossicular disruption) ..so d for disruption type Ad is seen in disruption..
Type B is seen when tympanic membrane bulges out(means it becomes dome shaped)..
So B for Bulges out.. so Type B is seen in Bulging of tympanic membrane (Tympanic membrane bulges in conditions where fluid is present inside the middle ear)...
Type C is seen in condition where tympanic membrane is retracted inwards..
