The MSFB group had a lower rate of Haller cells than the normal group (10% vs 22%, respectively; P &lt; .05). Also, the MSFB group had a wider maxillary sinus ostium than the normal group (7.07 \u00b1 1.8 vs 5.48 \u00b1 1.3 mm; P &lt; .01). Moreover, the combination of CB and Haller cells was significantly associated with a decreased rate of the fungal ball ( P = .047, odds ratio = 0.694). The dental factors were more prevalent in the MSFB and CRS groups (73% and 75%, respectively) than in the normal group (32%, P &lt; .001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Maxillary sinus fungal ball is significantly associated with CB, Haller cells, an increased maxillary sinus ostium size, and dental factors.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/01455613211028470","type":"journal-article","created":{"date-parts":[[2021,6,29]],"date-time":"2021-06-29T01:22:47Z","timestamp":1624929767000},"page":"727-732","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Anatomical Variations Associated With Maxillary Sinus Fungal Ball"],"prefix":"10.1177","volume":"102","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6214-3881","authenticated-orcid":false,"given":"Mohammed","family":"Basurrah","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea"},{"name":"Department of Surgery, College of Medicine, Taif University, Taif, Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Il Hwan","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Incheon St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Incheon, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Do Hyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8981-2536","authenticated-orcid":false,"given":"Sung Won","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6917-5998","authenticated-orcid":false,"given":"Soo Whan","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Seoul St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,6,28]]},"reference":[{"key":"bibr1-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1002\/lary.20520"},{"key":"bibr2-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-6665(00)80013-4"},{"key":"bibr3-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-007-0281-5"},{"key":"bibr4-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1100\/2012\/181246"},{"key":"bibr5-01455613211028470","doi-asserted-by":"publisher","DOI":"10.3342\/ceo.2012.5.4.213"},{"key":"bibr6-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1159\/000504963"},{"key":"bibr7-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2015.12.013"},{"key":"bibr8-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1620\/tjem.232.201"},{"key":"bibr9-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1177\/000348940911800708"},{"key":"bibr10-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-019-05738-5"},{"key":"bibr11-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2017.01.014"},{"key":"bibr12-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1002\/lary.20578"},{"key":"bibr13-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-019-05408-6"},{"key":"bibr14-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1002\/alr.22007"},{"key":"bibr15-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-017-4468-0"},{"key":"bibr16-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1177\/1945892420905186"},{"key":"bibr17-01455613211028470","doi-asserted-by":"publisher","DOI":"10.1016\/j.tripleo.2006.08.014"},{"key":"bibr18-01455613211028470","doi-asserted-by":"publisher","DOI":"10.3342\/ceo.2010.3.3.136"}],"container-title":["Ear, Nose &amp;
