The surface area (SA) of bony sinus and airspace on all sinus slices was determined using Dolphin and multiplied by slice thickness (0.4 mm) to calculate volume. Mucosal thickening was the difference between bony sinus and airspace volumes. The number of slices with bony sinus and airspace outlines was totaled. Right and left sinus values for each group were pooled ( t tests, P &gt; .05; n = 30 each group). All measures were compared (principal components analysis, multivariate analysis of variance, analysis of variance) by group and age ( P \u2264 .016 was considered significant).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Principal components analysis axis 1 and 2 explained 89.6% of sample variance. Principal components analysis showed complete separation based on the sample on axis 1 only. Age groups showed some separation on axis 2. Unilateral cleft lip and palate subjects had significantly smaller bony sinus and airspace volumes, fewer bony and airspace slices, and greater mucosal thickening and percentage mucosal thickening when compared with controls. Older subjects had significantly greater bony sinus and airspace volumes than younger subjects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Children with UCLP have significantly more maxillary sinus mucosal thickening and smaller sinuses than controls.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1597\/15-005","type":"journal-article","created":{"date-parts":[[2015,9,25]],"date-time":"2015-09-25T11:24:14Z","timestamp":1443180254000},"page":"640-648","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["Cone-Beam Computed Tomography Analysis of Mucosal Thickening in Unilateral Cleft Lip and Palate Maxillary Sinuses"],"prefix":"10.1177","volume":"53","author":[{"given":"Katherine","family":"Kula","sequence":"first","affiliation":[{"name":"Department of Orthodontics and Oral Facial Genetics, School of Dentistry, Indiana University, Indianapolis, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lindsay N.","family":"Hale","sequence":"additional","affiliation":[{"name":"Department of Mathematical Sciences, Indiana University\u2013Purdue University Indianapolis, Indianapolis, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Ghoneima","sequence":"additional","affiliation":[{"name":"Orthodontic Imaging Center, Department of Orthodontics and Oral Facial Genetics, School of Dentistry, Indiana University, Indianapolis, Indiana"},{"name":"Faculty of Dental Medicine, Al-Azhar University, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sunil","family":"Tholpady","sequence":"additional","affiliation":[{"name":"Division of Plastic Surgery, Department of Surgery, Indiana University, Indianapolis, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John M.","family":"Starbuck","sequence":"additional","affiliation":[{"name":"Department of Anthropology, University of Central Florida, Orlando, Florida."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,11,1]]},"reference":[{"key":"bibr1-15-005","unstructured":"American College of Allergy, Asthma & Immunology.
