Hello to all.
There is a medical doctor in Pittsburgh that specializes in middle ear problems and ETD. He is a pediatric ENT but does see adults. I had appointment with him several weeks ago and he does extremely extensive tests to diagnose and treat patients with these problems. The evaluation took 3 hours and involved numerous machines and a 4 team nursing staff. If after all of these tests he diagnoses the patient with ETD he then will develop a course of treatment to eliminate the problem. In many cases he finds the problem is NOT ETD but a middle ear issue that resembles ETD. He then recommends a treatment for that diagnosis. This doctor is affiliated with UPMC (University of Pittsburgh Medical Center). The doctor's name is Dr. ALPER. The one unfortunate thing is that he only runs these extensive diagnostic tests twice per month so appointments take about 4-6 months to get. He treats patients from across the USA at his practice at the Children's Hospital of UPMC. Most insurance covers the testing but it is wise to investigate coverage prior to the appointment. Because of the extensiveness of the testing and the personnel involved the total cost for the test without insurance is quite high. If you need more information please let me know. I can forward the phone number to you privately, however, if you look up Dr. ALPER at UPMC you should be able to locate number, address, etc.
