Use the Practo app to consult a good ENT Specialist locally at Kolkata, who does Coblation assisted ENT Surgeries. You are most welcome to come down to my clinic in Bangalore where I routinely do these revision surgeries. Conventional adenoidectomies are blind dissection surgeries where commonly some adenoid tissue still remains which proliferates later on. Coblation adenoidectomy is done under direct endoscopic vision and is accurate and almost painless procedure.
