This retrospective study assessed the orthognathic surgery procedures in two universities, using the Index of Orthognathic Functional Treatment Need (IOFTN), and compared the IOFTN grades according to gender as well as sagittal and vertical skeletal relationships. Material and Methods: Records of 200 consecutive patients (120 females, 80 males, mean age = 23.4 (SD: 5.4) years) who received orthognathic treatment (2014\u20132018) were analyzed. Sagittal (ANB angle) and vertical skeletal type (GoGnSN angle), osteotomies, and IOFTN scores were recorded. Results: Class III, II, and I malocclusions formed 69%, 17.5%, and 13.5% of the samples, respectively. Class III skeletal relationships (69%) and high-angle cases (64%) were the most prevalent (p &lt; 0.05). IOFTN scores were unevenly distributed among genders (p &lt; 0.05) and the prevalent scores were 5.3 (40.5%), 4.3 (15.5%), 5.4 (13%), and 5.2 (7.5%), with 94% scoring 4 or 5 (great and very great functional need). Bimaxillary osteotomies were the most prevalent (55%), followed by LeFort I (32%), and 26% had genioplasty. Conclusion: IOFTN is a reliable tool to identify patients in need of orthognathic surgery. Class III malocclusions and Class III sagittal skeletal relationships were more common in this sample. Comparatively, a higher number of patients had genioplasty as a part of their treatment.<\/jats:p>","DOI":"10.3390\/ijerph16111881","type":"journal-article","created":{"date-parts":[[2019,5,28]],"date-time":"2019-05-28T11:18:09Z","timestamp":1559042289000},"page":"1881","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Orthognathic Surgery Treatment Need in a Turkish Adult Population: A Retrospective Study"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5957-5819","authenticated-orcid":false,"given":"Hatice K\u00fcbra","family":"Olkun","sequence":"first","affiliation":[{"name":"Department of Orthodontics, School of Dentistry, \u0130stanbul Okan University, \u0130stanbul 34959, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3729-2348","authenticated-orcid":false,"given":"Ali","family":"Borzabadi-Farahani","sequence":"additional","affiliation":[{"name":"Orthodontics, Department of Clinical Sciences and Translational Medicine, University of Rome Tor Vergata, 00183 Rome, Italy"},{"name":"Finchley Orthodontics, North Finchley, London N12 9EN, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sina","family":"U\u00e7kan","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, School of Dentistry, \u0130stanbul Medipol University, \u0130stanbul 34214, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,28]]},"reference":[{"key":"ref_1","first-page":"806","article-title":"Spectrum and management of dentofacial deformities in a multiethnic Asian population","volume":"76","author":"Chew","year":"2006","journal-title":"Angle Orthod."},{"key":"ref_2","unstructured":"Posnick, J.C.
