There was a significant difference in surgical approach according to pneumatization of the maxillary sinus when middle meatal antrostomy (MMA) was performed alone or combined with MMA and inferior meatal antrostomy (IMA) (p=0.042). Extension of a maxillary sinus lesion caused by fungus ball was not associated with stenosis of the MMA (p=0.328).Conclusion: Diagnosis of maxillary sinus fungus on CT was associated with irregular lesion surface or a protruding calcification. In patients with fungus ball of the maxillary sinus, the more severe is the maxillary sinus pneumatization, the larger is the extent of IMA needed.<\/jats:p>","DOI":"10.18787\/jr.2021.00392","type":"journal-article","created":{"date-parts":[[2022,3,28]],"date-time":"2022-03-28T08:01:09Z","timestamp":1648454469000},"page":"32-37","update-policy":"https:\/\/doi.org\/10.18787\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Clinical Characteristics According to the Radiological Classifications of Maxillary Sinus Fungus Ball"],"prefix":"10.18787","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0439-7012","authenticated-orcid":true,"given":"Dong-Hyun","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8043-5404","authenticated-orcid":true,"given":"Jung-Hun","family":"Kown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1342-9450","authenticated-orcid":true,"given":"Hyung-Bon","family":"Koo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0856-8173","authenticated-orcid":true,"given":"Jae-Hoon","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7989","container-title":["Journal of Rhinology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/j-rhinology.org\/upload\/pdf\/jr-2021-00392.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/j-rhinology.org\/journal\/view.php?doi=10.18787\/jr.2021.00392","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/j-rhinology.org\/upload\/pdf\/jr-2021-00392.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,3,28]],"date-time":"2022-03-28T08:01:31Z","timestamp":1648454491000},"score":1,"resource":{"primary":{"URL":"http:\/\/j-rhinology.org\/journal\/view.php?doi=10.18787\/jr.2021.00392"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,3,31]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2022,3]]}},"URL":"https:\/\/doi.org\/10.18787\/jr.2021.00392","relation":{},"ISSN":["2384-4361"],"issn-type":[{"value":"2384-4361","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,3,31]]},"assertion":[{"value":"2021-09-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-12-07","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-03-28","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-03-31","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
