Epidemiology of odontogenic sinusitis: an old, underestimated disease, even today. A narrative literature review.

Odontogenic sinusitis is an inflammatory condition of the paranasal sinuses resulting from dental pathology. The aim of this study is to provide an overview of the current literature on the dimensions of the phenomenon, quality of life, economic considerations, and approaches to odontogenic sinusitis. A narrative review was conducted following the methodology proposed by Green et al. (2006). There appears to have been an increase in the incidence over the last decade. Nowadays, evidence in the literature reports that 10-12% up to 40% of all sinusitis cases are associated with odontogenic infections. The iatrogenia was by far the leading cause of odontogenic sinusitis (55.97%) while the first and second molars were the most affected teeth with an incidence of 35.6% and 22%. If not properly diagnosed and treated, these infections may lead to a rapid spread, giving rise to potentially life-threatening complications with a significant general health-related Quality of Life detriment. The proper management of patients in a pre-implant logical setting leads to substantial savings, ranging from €38 million to €152 million, for the Italian National Health Service. Odontogenic sinusitis management should involve shared decisionmaking between the otolaryngologist, dental provider, and patient, where the benefits and risks of dental treatment and endoscopic sinus surgery are discussed.
