Welcome in H.C.M.
I have gone through your query regarding recurrence of tumor
in your left ear and same had been operated in yor childhood.
Now I can't reach to any diagnosis by this short history of illness. I want to see the operative record of that time just to know the real fact about nature of tumor. If old records are not available than you should do these investigations-
1- C.T.Scan of ear of left side.
2- Doppler's study.
By inferences of these investigations and clinical findings one may reach to correct diagnosis which may be managed accordingly.
