The incidence of MSDO in published series is reported to be from 10% to 40% in bacterial sinusitis. We present this series to highlight clinical and radiologic indicators of MSDO.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Databases from the authors' otolaryngology and endodontic practices were reviewed to identify patients who had been seen mutually. Sixty\u2010seven (67) patients were identified. Both authors then reviewed the clinical records and associated computed tomography (CT) scans and determined that 31 patients had MSDO and 2 of had bilateral MSDO, for a total of 33 cases. The clinical and radiologic features related to these cases were then tabulated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The clinical characteristics of the 33 cases of MSDO were as follows: sinus pain (88%), postnasal drainage (64%), congestion (45%), maxillary toothache (39%), and foul drainage (15%). Radiographic CT findings of MSDO showed periapical abscess in 18 cases (55%), periodontal abscess in 3 cases (9%), and no obvious dental pathology in 12 cases (36%). The extent of associated sinusitis was variable from mucoperiosteal thickening to florid unilateral sinusitis involving multiple sinuses. Eighteen maxillary sinuses (55%) were found to have either patent maxillary infundibula or prior surgical antrostomy. Twenty\u2010four patients (77%) had unilateral maxillary sinus disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>MSDO should be considered highly likely when radiographic evidence of dental pathology is associated with maxillary sinus disease. Regardless of negative CT evidence of dental pathology, MSDO should be suspected when unilateral maxillary sinus disease is seen, particularly when associated with a patent infundibulum. When MSDO is suspected, a clinical endodontic examination should be performed to rule out or treat an odontogenic etiology.<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.21212","type":"journal-article","created":{"date-parts":[[2013,8,27]],"date-time":"2013-08-27T14:18:43Z","timestamp":1377613123000},"page":"973-979","source":"Crossref","is-referenced-by-count":79,"title":["Clinical and radiologic findings in a case series of maxillary sinusitis of dental origin"],"prefix":"10.1002","volume":"3","author":[{"given":"Al","family":"Pokorny","sequence":"first","affiliation":[{"name":"Spokane ENT Clinic  Spokane WA"},{"name":"University of Washington Department of Otolaryngology\u2013Head and Neck Surgery  Seattle WA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roderick","family":"Tataryn","sequence":"additional","affiliation":[{"name":"Tataryn Endodontics  Spokane WA"},{"name":"Department of Endodontics School of Dentistry, Loma Linda University  Loma Linda CA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,8,27]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0096-6347(43)90011-0"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11908-008-0034-7"},{"key":"e_1_2_6_4_1","first-page":"591","article-title":"Maxillary sinusitis of odontogenic origin","volume":"34","author":"Maloney PL","year":"1968","journal-title":"J Can Dent Assoc (Tor)"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.20095"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2011.02.032"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.131.11.1017"},{"key":"e_1_2_6_8_1","first-page":"78","article-title":"The effect of chronic pyogenic infections on the maxillary sinus","author":"Fleming WE","year":"1954","journal-title":"Qld Dent J"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016488609132845"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/alr.20058"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.2500\/ajra.2010.24.3479"},{"key":"e_1_2_6_12_1","first-page":"S1","article-title":"Clinical practice guideline: adult sinusitis","volume":"137","author":"Rosenfeld RM","year":"2007","journal-title":"Otolaryngology"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215111002568"},{"key":"e_1_2_6_14_1","first-page":"626","volume-title":"Ingle's Endodontics","author":"Tataryn RW"},{"key":"e_1_2_6_15_1","first-page":"111","article-title":"Radiographic interpretation of antral mucosal changes due to localized dental infection","volume":"38","author":"Worth HM","year":"1972","journal-title":"J Can Dent Assoc"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1985.00800120037003"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1985.00800110054002"},{"key":"e_1_2_6_18_1","first-page":"e70","article-title":"Meta\u2010analysis of the etiology of odontogenic maxillary sinusitis","volume":"15","author":"Arias\u2010Irimia O","year":"2010","journal-title":"Med Oral Patol Oral Cir Bucal"}],"container-title":["International Forum of Allergy &amp; Rhinology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Falr.21212","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Falr.21212","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/alr.21212","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T04:00:39Z","timestamp":1696564839000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/alr.21212"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,8,27]]},"references-count":17,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2013,12]]}},"alternative-id":["10.1002\/alr.21212"],"URL":"https:\/\/doi.org\/10.1002\/alr.21212","archive":["Portico"],"relation":{},"ISSN":["2042-6976","2042-6984"],"issn-type":[{"value":"2042-6976","type":"print"},{"value":"2042-6984","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,8,27]]}}}
