The cleft-columellar angle was measured as defined by the intersection of a line in the parasagittal plane and a line perpendicular to the columellar base along the midcolumellar line. The association between deformity ratings and the cleft-columellar angle was modeled using mixed-model regression analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Setting<\/jats:title>\n                    <jats:p>Tertiary care academic medical center.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>After accounting for within-rater and within-child effects, the cleft-columellar angle explained a statistically significant portion of the variance in the rated severity for lip deformity (49%, p = .0012), nasal deformity (57%, p = .0001), and overall deformity (57%, p = .0005).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Measurement of the cleft-columellar angle in two-dimensional digital photography is simple and correlative, capturing a substantial portion of nonexpert severity ratings of the constellation of deformities seen with the unilateral cleft lip deformity. Given its ease of application, the cleft-columellar angle is a useful variable in the description of the unilateral cleft lip deformity and may find utility across institutions as cleft surgeons seek to advance surgical care through outcomes research.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1597\/10-176","type":"journal-article","created":{"date-parts":[[2012,1,11]],"date-time":"2012-01-11T10:20:11Z","timestamp":1326277211000},"page":"82-87","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["The Cleft-Columellar Angle: A Useful Variable to Describe the Unilateral Cleft Lip-Associated Nasal Deformity"],"prefix":"10.1177","volume":"50","author":[{"given":"Noah E.","family":"Meltzer","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Division of Facial Plastic & Reconstructive Surgery, Johns Hopkins Medical Institutions, Baltimore, Maryland, and Greater Baltimore Cleft Lip and Palate Team, Baltimore, Maryland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dhananjay","family":"Vaidya","sequence":"additional","affiliation":[{"name":"Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randolph B.","family":"Capone","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Division of Facial Plastic and Reconstructive Surgery, Johns Hopkins Medical Institutions, Baltimore, Maryland; Greater Baltimore Cleft Lip and Palate Team, Baltimore, Maryland; and Baltimore Center for Facial Plastic Surgery, Baltimore, Maryland."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,1,1]]},"reference":[{"key":"bibr1-10-176","doi-asserted-by":"publisher","DOI":"10.1080\/02844310601029837"},{"key":"bibr2-10-176","doi-asserted-by":"publisher","DOI":"10.1597\/06-009"},{"key":"bibr3-10-176","doi-asserted-by":"publisher","DOI":"10.1597\/1545-1569_1993_030_0001_aaafot_2.3.co_2"},{"key":"bibr4-10-176","doi-asserted-by":"publisher","DOI":"10.1597\/1545-1569_2003_040_0544_aqtaoa_2.0.co_2"},{"key":"bibr5-10-176","doi-asserted-by":"publisher","DOI":"10.1097\/PRS.0b013e3181811a52"},{"key":"bibr6-10-176","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-199905000-00007"},{"key":"bibr7-10-176","doi-asserted-by":"publisher","DOI":"10.1109\/IEMBS.2006.260429"},{"key":"bibr8-10-176","doi-asserted-by":"publisher","DOI":"10.1597\/07-188.1"},{"key":"bibr9-10-176","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-200209010-00001"},{"key":"bibr10-10-176","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-199609001-00006"}],"container-title":["The Cleft Palate Craniofacial Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1597\/10-176","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1597\/10-176","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1597\/10-176","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T16:17:17Z","timestamp":1777393037000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1597\/10-176"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,1]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2013,1]]}},"alternative-id":["10.1597\/10-176"],"URL":"https:\/\/doi.org\/10.1597\/10-176","relation":{},"ISSN":["1055-6656","1545-1569"],"issn-type":[{"value":"1055-6656","type":"print"},{"value":"1545-1569","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,1]]}}}
