Practicing since 1991
I would always be a little concerned about a surgeon "demanding" to do a procedure. Our responsibility is to provide a diagnosis and explanation of the benefits, risks and alternatives to any procedure offered to address a given condition. In the case of enlarged turbinates, the patient would be experiencing nasal obstruction or difficulty breathing on one or both sides. Enlarged turbinates can been seen by a patient holding a mirror during an inside the nose exam or a picture can be taken using an endoscope. Xrays are of little or no value but a CT scan or MRI, both expensive studies, allows for clear visualization. I would suggest the surgeon take photos of the enlarged turbinates, show them to you and discuss the anatomy and procedure proposed to improve your breathing. I am assuming that this is being proposed while performing a rhinoplasty or "nose job" surgery to improve your breathing.
