BOYER - 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.
TATARYN - 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.
