Dr. Karanfilov served as the senior principal investigator for the second in-office trial, ORIOS II. This study was the largest study to date evaluating the use of in-office balloon dilation. The title of the study is Office-Based Balloon Sinus Dilation: A prospective multi-center study of 203 patients. 203 patients were enrolled and underwent balloon dilation in the office setting under local anesthesia for medically refractory chronic sinusitis. The patients were followed out for 6 months after the procedure. The success of dilating a particular sinus was greater than 93%. Patients completed surveys and had cat scans and endoscopy to make certain the sinuses remained open. Surveys showed that patients achieved significant improvement in their sinus symptoms, cat scans confirmed this improvement and the great majority of patients felt the procedure to be very tolerable. There were no major complications.
Dr. Karanfilov’s most recent publication compared balloon sinus dilation to medical therapy for chronic sinusitis. The study was recently published and shows that balloon procedures are superior to medical treatment of refractory chronic sinusitis. Dr. Karanfilov is the most experienced balloon sinus expert in the area. He has published extensively and has been invited as an international lecturer and teacher of this technology. His invitations to speak have taken him to Russia, Spain, Bulgaria, Macedonia, Dubai and many locations in the U.S. He has performed live surgery during national ENT society meeting and has presented at various sinus courses. He has a wealth of knowledge, training, and research in this technology that is unmatched in Central Ohio.
