Materials and Methods: We have evaluated 24 CT images of children with choanal atresia treated at the Department of Pediatric Otorhinolaryngology FM CU and the NICD Bratislava (Slovakia). In accordance with the methodology used by Slovis et al. (1985), we have measured parameters related to anomalous development in the nasal cavity: vomer width, the width of soft atresia and the width of the air space of unilaterally developed choana. Results: In the group of 24 patients, 11 (46%) were male and 13 (54%) were female. The age of patients at the time of CT imaging varied. Associated syndromes had been manifested in 11 (46%) children, with 7 (29%) patients having CHARGE syndrome. In 13 (54%) cases it was a bone membranous type of atresia, in 8 (33%) cases a membranous type, and in 3 (13%) patients a bone type. Among the group of patients, unilateral disorder was present in 13 (54%) patients and bilateral in 11 (46%). Based on the Pearson\u2019s correlation test, we have found in the studied group that the width of the vomer correlates with age, and the vomer is wider in bone atresia than in the membranous ones. Based on determining the average vomer\u2019s width within the age groups 0\u20138 and &gt;8\u201320, compared to the standard widths, we found that the vomer\u2019s widths reached the upper limits of the standard \u00b12 SD (cm) or even exceeded that limit. The same applies to the width in soft choanal atresia. On the other hand, the width of the developed choana in the case of unilateral atresia is almost standard. Conclusions: The above findings are the basis for selecting the appropriate type of surgery. Currently, the gold standard is the endoscopic fenestration. associated with posterior septotomy.<\/jats:p>","DOI":"10.3390\/medicina57020093","type":"journal-article","created":{"date-parts":[[2021,1,21]],"date-time":"2021-01-21T09:49:21Z","timestamp":1611222561000},"page":"93","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Nasal Cavity CT Imaging Contribution to the Diagnosis and Treatment of Choanal Atresia"],"prefix":"10.3390","volume":"57","author":[{"given":"Irina","family":"\u0160ebov\u00e1","sequence":"first","affiliation":[{"name":"Department of Pediatric Otorhinolaryngology, Faculty of Medicine, Comenius University and National Institute of Children\u2019s Diseases, 83101 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3986-4645","authenticated-orcid":false,"given":"Ivana","family":"Vyrvov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Pediatric Otorhinolaryngology, Faculty of Medicine, Comenius University and National Institute of Children\u2019s Diseases, 83101 Bratislava, Slovakia"},{"name":"Faculty of Medicine, Masaryk University, 62500 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Barkociov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Pediatric Otorhinolaryngology, Faculty of Medicine, Comenius University and National Institute of Children\u2019s Diseases, 83101 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"339","DOI":"10.1016\/j.otc.2009.01.001","article-title":"Choanal atresia and choanal stenosis","volume":"42","author":"Ramsden","year":"2009","journal-title":"Otolaryngol.
