Welcome in H.C.M.
I have gone through your query regarding recurrent mass formation in your ear canal
, not responding to medicine and local steroids
In connection to above matter I would like to say that you should go for these investigations-
(1) Cytological and biochemica examination of removed mass and debris.
(2) Blood sugar F & PP.
(3) C/S of ear pus.
By inferences of these investigations and co-relation with clinical findings one can reach to correct diagnosis which may plan for treatment .
I hope your query is explained well.
