CE: 2.0

Course Description: During this session we will discuss the implications of the anatomical relationship of the maxillary sinus and the upper dentition. After presenting an overview of normal sinus anatomy and physiology, we will discuss the pathophysiologic processes that contribute to rhinosinusitis, emphasizing the differentiation between rhinogenic and odontogenic etiologies. We will use example cases to demonstrate these learnings.

The pathological extension of endodontic disease into the maxillary sinus and its sequelae are often unrecognized in medical and dental practice. Despite extensive scientific recognition and reported high prevalence, dental infection manifesting in the maxillary sinus continues to remain under-appreciated, and often misdiagnosed and treated as rhinogenic sinusitis. This lecture explains the progression of endodontic infection in the sinuses and the associated clinical and radiographic findings. The goal is to help practitioners recognize maxillary sinusitis of endodontic origin (MSEO) through accurate diagnosis and appropriate treatment, and improve communication with physicians and ENT specialists.

At the conclusion, participants should be able to:

• Describe sinus anatomy and normal sinus physiology and the patholophysiologic processes that contribute to sinusitis.
• Summarize the diagnosis and treatment of rhinogenic sinusitis.
• Describe the progression and pathogenic effects of endodontic infection in the sinus and the associated clinical and radiographic findings of maxillary sinusitis of endodontic origin (MSEO).

Description:The American Association of Endodontists is dedicated to excellence in endodontics and promoting the highest standards of patient care. This following position statement is intended to define and outline Maxillary Sinusitis of Endodontic Origin (MSEO), deliver guidelines for its diagnosis and appropriate treatment, and provide a standard for all dental and medical practitioners who undertake the responsibility of managing patients with this condition. The relationship between dental infections and sinus disease is widely recognized in both the dental and medical literature. Despite extensive scientific recognition and reported high prevalence, periapical infection manifesting in the maxillary sinus remains under-appreciated and frequently goes undiagnosed by dentists, otolaryngologists, and radiologists alike, with its sequelae often misdiagnosed as sinogenic sinusitis. Recognition of MSEO is critical as failure to identify and properly manage the endodontic source pathology will result in the persistence of sinus disease, the failure of medical sinus therapies, and the potential advancement to more serious or even life-threatening cranio-facial infections.

At the conclusion, participants should be able to:

• Describe a maxillary sinusitis of endodontic origin (MSEO) and how periradicular infection can directly cause a maxillary sinus infection.
• Describe the variety of typical symptoms that a patient may experience with MSEO.
• Recognize and describe the various pathological effects and radiographic presentations of periapical inflammation on the maxillary sinus tissues, including periapical mucositis, periapical osteoperiostitis, and sinus obstruction.
