Abstract: Odontogenic infection is a possible cause of maxillary sinusitis. In this case series, the authors evaluated patients who presented with maxillary sinusitis symptoms before and after dental treatment Odontogenic maxillary sinusitis (OMS) is a common cause of chronic rhinosinusitis (CRS); however, the condition is infrequently mentioned in recent rhinosinusitis guidelines and often overlooked as a cause of sinusitis by otolaryngologists, dentists, and radiologists

Cone-beam CT (CBCT), a low-radiation alternative to conventional CT, is a better option than plain radiographs in the diagnosis of odontogenic sinusitis Purpose: To retrospectively review computed tomographic (CT) and clinical findings in patients with odontogenic orbital infection. Materials and Methods: Approval from the institutional review board was obtained for chart and scan review, and informed consent was waived for this HIPAA-compliant study. Five patients, two male and three female (median age, 37 years; age range, 13-55 years. Close proximity of the maxillary roots and the sinus floor makes dental disease a probable cause of maxillary sinusitis [1, 2].The real incidence of odontogenic maxillary sinusitis (OMS) is still unknown these days, but according to recent publications, it has been up to 40% compared to previously mentioned 10% of all maxillary sinusitis cases [2,3,4,5,6,7] We describe a patient with odontogenic keratocyst of the maxillary sinus. Differential diagnosis with expanding intrasinusal cyst can be assessed on the basis of CT findings: upward displacement of the inferior floor of the maxillary sinus is a peculiar finding in extrasinusal masses: as a consequence, the size of maxillary sinus is reduced. Odontogenic sinusitis (second name sinusitis) is an inflammation of the mucosa of the maxillary sinus, which arises as a result of the focus of infection in the mouth.

ODS is an infectious condition of the paranasal sinuses that can occur from either dental infection or dental procedures involving. Introduction. Maxillary sinusitis (acute or chronic) is defined as a symptomatic inflammation of the maxillary sinus, usually caused by viral, bacterial, allergic or fungal rhinitis. 1 However, any disease arising from dental or dentoalveolar structures could damage the floor of the maxillary sinus leading to a sinusitis known as odontogenic maxillary sinusitis (OMS)

Odontogenic sinusitis has distinct pathophysiology, diagnostic considerations, microbiology, and treatment strategies whenever compared with chronic rhinosinusitis. Clinicians who can accurately identify odontogenic sources can increase efficacy of medical and surgical treatments and improve patient outcomes Discussion. An AOT is an uncommon benign lesion [1] defined as a tumour of odontogenic epithelium with duct-like structures and with varying degrees of inductive change in the connective tissue. The 2017 edition of the WHO classification classified it in the category of tumours composed of odontogenic epithelium only

Odontogenic sinusitis is associated with periodontal disease and/or endodontic infection in close proximity to the floor of the sinus. 1 Posterior maxillary dentition that presents with periapical infection has been shown to affect the maxillary sinus mucosa even without perforation of the cortical bone, with the infection spreading to the sinus via blood vessels, lymphatics, and bone marrow. ase series and reviews of odontogenic sinusitis that characterize and discuss emerging diagnostic modalities in odontogenic sinusitis.
