BACKGROUND: Endoscopic sinus surgery (ESS) is reported to improve symptoms in approximately 85% of patients. Reasons for failure include misdiagnosis, technical inadequacies, underlying severe hyperplastic disease, biofilm, and immunodeficiency. Only one previous case of unrecognized odontogenic maxillary sinusitis has been cited in the literature as a reason for failure to improve with sinus surgery. This study was designed to characterize clinical and radiographic findings in patients who fail to improve with ESS because of an unrecognized dental etiology. METHODS: Five patients, with odontogenic maxillary sinusitis with prior unsuccessful ESS, were prospectively enrolled. Demographics and clinical aspects including duration of illness, prior sinus surgeries and therapies, and radiographic data were assessed. RESULTS: Five adults underwent an average of 2.8 sinus surgeries with persistence of disease and symptoms until their dental infection was treated. Duration of symptoms ranged from 3 to 15 years. In four of five patients, the periapical abscess was not noted on the original CT report but could be seen in retrospect. Three of five patients had been seen by their dentists and told they had no dental pathology. All five patients underwent dental extractions and one patient underwent an additional ESS after dental extraction. These procedures led to a resolution of sinusitis symptoms in all five patients. CONCLUSION: 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.
