When Maxillary Sinusitis Does Not Heal: Findings on CBCT Scans of the Sinuses With a Particular Focus on the Occurrence of Odontogenic Causes of Maxillary Sinusitis

Abstract: ObjectivesThis study sought to investigate the proportion of patients with suspected sinusitis referred for radiological examination who have radiologically verified sinusitis of odontogenic origin and to describe this type of sinusitis.Study DesignThis investigation is a retrospective study.MethodsA total of 303 sinus examinations involving cone beam computed tomography (CBCT) performed at Sunderby Hospital, Luleå, Sweden in 2012 were independently reviewed by two radiologists. The number of cases of maxillar… Show more

“…The high prevalence of OMS in this study matches previous studies of patients with unilateral maxillary sinusitis diagnosed with CT, showing OMS in 40-70% [14,15,20]. The patients who had a dental evaluation prior to being referred to the university ENT clinic had OMS in 70% of cases, whereas the patients who had a dental evaluation after being referred to the university ENT clinic had OMS in 39% of cases.…”

“…For instance, a dental history could be accidental in relation to the unilateral CT findings and symptoms. OMS has been found to be bilateral in 6% of sinusitis patients, but bilateral sinusitis was excluded in this study [20]. The dental treatment given to the patients with OMS was not investigated, as the medical records only contained short communications on whether treatment had or had not been given.…”

“…It included all articles published between the year 2000 and 2018. The keywords used were “odontogenic sinusitis,” “chronic maxillary sinusitis,” “sinusitis of dental origin,” “sinusitis of undetermined origin,” “chronic apical periodontitis,” “periapical pathology and sinusitis,” and “iatrogenic sinusitis.” All the articles including case reports, case series, review, retrospective, and prospective studies were sorted out to gather all descriptions regarding odontogenic cause of maxillary sinusitis, and the type of imaging modality used[8910111213141516171819202122232425262728293031] [Table 6].…”

“…Odontogenic sinusitis (OS) deserves special consideration because of some differences in pathophysiology, microbiology, and management as compared with sinus disease of other origins. The relationship between odontogenic infections and maxillary sinusitis is well established . The roots of the molars in the upper jaw are usually extremely close to or in direct contact with the maxillary sinus.…”
