Education and Experience

Ohio Sinus Institute has always been active in cutting edge clinical research and has been involved in a number of research  projects over the years.  In 2005, a new technology, balloon sinus dilation was introduced by a California based company and Dr. Karanfilov was invited to perform the first case in Ohio and served as a contributing author of the landmark clinical study  that assessed the safety and effectiveness of this technology.  As the techniques evolved and were refined, balloon dilation of blocked sinus passageways were introduced for office use.  We performed our first in office balloon sinuplasty in 2007 and then joined a national clinical trial ORIOS I to test the feasibility of performing the procedure under local anesthesia in the office setting.  Dr. Karanfilov was then invited to be the primary author for the largest clinical trial to date, greater than 200 patients, to further refine and report on the results of office based balloon sinus dilation for chronic sinusitis sufferers.  This study was presented at the national annual American Rhinologic Society Meeting and was published in the highly respected peer reviewed journal, International Forum of Allergy and Rhinology in 2013.


Dr. Karanfilov has been invited to lecture nationally and internationally on balloon sinus dilation but also other complex Rhinologic topics.  He has traveled as an invited speaker and expert surgeon all over the U.S. and also internationally to Siberia, Dubai, Bulgaria, Spain and Macedonia.  During these meetings he has performed both cadaveric dissections for participants and has performed live surgeries of both balloon dilation and advanced frontal sinus techniques.  In Siberia he performed two closed circuit televised cases for the entire Russian ENT society and was interviewed by local reporters.


Dr. Karanfilov has published on his research endeavors  instructed and developed sinus surgery courses for residents in training, lectured extensively and has authored a book chapter on endoscopic management of frontal sinus disease.   As a resident Dr. Karanfilov participated in Project Ear, a medical mission to the Dominican Republic to help patients in desperate need of ENT care.  He has continued his mission work with several trips to the Republic of Macedonia where he has been invited to perform surgeries and was the first surgeon in the country to perform an Endoscopic CSF Leak repair with Computer Navigational Image Guidance in 2010.
