Two calibrated examiners assessed the presence of PSA<\/jats:styled-content> canal on the postero\u2010lateral wall of the maxillary sinus using coronal sections. One examiner also recorded the presence of images compatible with sinus disease. Associations between the presence of PSA<\/jats:styled-content> canal and sinus disease were investigated for males and females separately using statistical methods.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 254 CBCT<\/jats:styled-content> scans were selected. The pooled prevalence of the PSA<\/jats:styled-content> canal in CBCT<\/jats:styled-content> scans was 94.4% and 91% on the right and left side, respectively. The ability to detect the presence of the canal was not significantly affected by the presence of intrasinusal disease. Males are more likely than females to present signs of maxillary sinus pathoses on the right (63.3% vs. 36.7%) and the left side (59.2% vs. 40.8%).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>The prevalence of the PSA<\/jats:styled-content> canal on CBCT<\/jats:styled-content> images in the selected population is high. The PSA<\/jats:styled-content> canal can be consistently visualized on CBCT<\/jats:styled-content> scans with a high level of reproducibility regardless of the presence of radiographic signs of intrasinusal pathoses.<\/jats:p><\/jats:sec>","DOI":"10.1111\/clr.12318","type":"journal-article","created":{"date-parts":[[2013,12,19]],"date-time":"2013-12-19T07:13:15Z","timestamp":1387437195000},"source":"Crossref","is-referenced-by-count":37,"title":["Prevalence of the posterior superior alveolar canal in cone beam computed tomography scans"],"prefix":"10.1111","volume":"26","author":[{"given":"Sindhura","family":"Anamali","sequence":"first","affiliation":[{"name":"Department of Oral Pathology, Radiology & Medicine University of Iowa College of Dentistry Iowa City IA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gustavo","family":"Avila\u2010Ortiz","sequence":"additional","affiliation":[{"name":"Department of Periodontics University of Iowa College of Dentistry Iowa City IA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satheesh","family":"Elangovan","sequence":"additional","affiliation":[{"name":"Department of Periodontics University of Iowa College of Dentistry Iowa City IA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Qian","sequence":"additional","affiliation":[{"name":"Biostatistics Unit University of Iowa College of Dentistry Iowa City IA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Axel","family":"Ruprecht","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology, Radiology & Medicine University of Iowa College of Dentistry Iowa City IA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Finkelstein","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology, Radiology & Medicine University of Iowa College of Dentistry Iowa City IA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veeratrishul","family":"Allareddy","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology, Radiology & Medicine University of Iowa College of Dentistry Iowa City IA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,12,19]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"613","article-title":"Grafting of the maxillary sinus floor with autogenous marrow and bone","volume":"38","author":"Boyne P.J.","year":"1980","journal-title":"Journal of Oral Surgery"},{"key":"e_1_2_7_3_1","first-page":"784","article-title":"Distribution of the maxillary artery as it relates to sinus floor augmentation","volume":"20","author":"Elian N.","year":"2005","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_7_4_1","first-page":"1047","article-title":"Vascular connections of the lateral wall of the sinus: surgical effect in sinus augmentation","volume":"23","author":"Ella B.","year":"2008","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.id.0000188437.66363.7c"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2010.02071.x"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0b013e31819ba1c1"},{"key":"e_1_2_7_8_1","first-page":"11","article-title":"Report of the Sinus Consensus Conference of 1996","volume":"13","author":"Jensen O.T.","year":"1998","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tripleo.2008.03.018"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2007.05.005"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1999.100105.x"},{"key":"e_1_2_7_12_1","first-page":"152","article-title":"A new concept in maxillary implant surgery: the osteotome technique","volume":"15","author":"Summers R.B.","year":"1994","journal-title":"Compendium"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0011-8532(22)02107-3"},{"key":"e_1_2_7_14_1","first-page":"255","article-title":"Ligation of an unusually large vessel during maxillary sinus floor augmentation.
