Thanks for writing to H.C.M. for your query.
I have gone through your query regarding sebaceous cyst
surgery for complete removal from external ear, In this connection I would like to say almost all the ENT doctor can do this because I have done this type of surgery so many times and it is not a difficult proceedure.
Since I am at Kanpur in India so it will be inconvinient to you, so it is my suggestion to please contact any senior ENT doctor at your nearby your problem will solve comfortably.
