Newswise — CHICAGO – After issuing its highly anticipated position statement on the condition known as Maxillary Sinusitis of Endodontic Origin (MSEO), the American Association of Endodontists is hosting a seminar for endodontists from around the world on MSEO during the Association’s annual event in Montréal known as AAE19.

In short, patients with long-term sinus problems could have an endodontic infection that manifests in the maxillary sinus and may have been misdiagnosed by dentists, ear nose and throat doctors (ENTs) or radiologists. MSEO refers specifically to sinusitis secondary to periradicular disease of endodontic origin, excluding sinusitis secondary to other dental etiologies — previously termed “the endo-antral syndrome.”

MSEO requires an accurate clinical diagnosis and tools such as cone beam CT imaging, followed by appropriate endodontic treatment. Again, the diagnosis of MSEO may be missed by a general practitioner but can be diagnosed and treated by highly skilled dentists, known as endodontists, working in tandem with ENTs.  

On Friday, April 12, Dr. Roderick W. Tataryn and Dr. Holly Boyer will team up to provide a multi-disciplinary talk called “Rhinosinusitis and Endodontic Disease”. Their coordinated lecture will explain the progression of endodontic infection in the sinuses and the associated clinical and radiographic findings. The goal of their informative presentation is to help practitioners recognize MSEO through accurate diagnosis and appropriate treatment and improve communication with physicians and ENT specialists. It will start at 10:00 a.m. and end at noon.

Dr. Tataryn is a member of the American Association of Endodontists. In addition to presenting on MSEO, he has authored several articles on the subject and has been featured in publications like the AAE’s Colleagues for Excellence, Journal of Endodontics, and Dear Doctor.

Dr. Boyer is an otolaryngologist, subspecializing in rhinology, practicing in an academic setting. She participates in the multidisciplinary care of patients with complex facial pain. Dr. Boyer is active in medical student and resident education at the University of Minnesota and is the executive medical director of ambulatory care for the academic practice.
