Unrecognized Odontogenic Maxillary Sinusitis: A Cause of Endoscopic Sinus Surgery Failure

Abstract

Unrecognized periapical abscess is a cause of ESS failure and the radiological report frequently will fail to note the periapical infection. Dentists are unable to recognize periapical abscesses reliably with dental x-rays and exam. In patients with maxillary sinus disease, the teeth should be specifically examined as part of the radiological workup.

Clinical aspects of odontogenic maxillary sinusitis: a case series

“…Recognition of OMS is important because failure to address the dental pathology can result in failure of medical and surgical therapies and persistence of symptoms. 8,9 We reviewed the English-language medical literature and CRS guidelines with attention to recognition and recommendations for OMS. Prospectively, we enrolled all patients in a 30-month period with OMS based on computed tomography (CT) scan and report on their clinical and demographic findings.…”

Chronic odontogenic paranasal sinusitis in the material provided by the Otorhinolaryngology Unit of the 4th Military Teaching Hospital in Wroclaw

“…18 These authors noted that in 65% of all cases, the radiological description did not consider odontogenic pathologies. Longhini et al 17 noticed a similar problem in 67% of cases.…”

“…The changes were confirmed only by CB-CT scans. 17 Obayashi et alnoted that 71.3% of tooth infections related to the jaw were associated with changes in the maxillary sinus. 16 What is important, in most cases, the clinical tests ruled out the presence of odontogenic infections.…”

“…17 The treatment was ineffective until odontogenic foci were removed. They also noted that in some cases, dentists who performed clinical tests and OPG excluded the potential presence of teeth-related pathologies.…”

Study of etiological factors in unilateral maxillary chronic sinusitis

“…Unilateral maxillary sinusitis poses a significant challenge to otorhinolayngologists as it is multifactorial and less well recognized causes like odontogenic factor is implicated in etiology which if not recognized leads to failure of treatment. 4 Odontogenic source should be considered with history of dental pain or dentoalveolar surgery and those with extended unilateral sinusitis or unilateral sinusitis resistant to conventional treatment. 5 Diagnostic nasal endoscopy with CT improves the diagnostic accuracy.…”
