We retrospectively examined the effects of helmet therapy according to the size of the anterior fontanelle. Two hundred patients with nonsynostotic plagiocephaly who underwent helmet therapy between 2016 and 2018 were included. Data regarding age at treatment onset and treatment duration were collected. Patients were divided into two groups depending on the age at treatment initiation: the 12\u201323 weeks group and the &gt;23 weeks group. Patients were also divided based on the anterior fontanelle size to analyze the effects of helmet therapy according to the severity of plagiocephaly in each group as the change in the cranial vault asymmetry index (CVAI). Therapeutic effects were evaluated using the cranial vault asymmetry (CVA), CVAI, anterior symmetry ratio, posterior symmetry ratio (PSR), and overall symmetry ratio at baseline and treatment completion. Treatment initiation at age 12\u201323 weeks resulted in better effects than that after age 24 weeks. There were no sex-dependent differences in therapeutic effects. Greater changes in the CVA, CVAI, and PSR were associated with larger anterior fontanelles. Therefore, the anterior fontanelle size could be a prognostic factor for estimating helmet therapy outcomes.<\/jats:p>","DOI":"10.3390\/jcm8111977","type":"journal-article","created":{"date-parts":[[2019,11,14]],"date-time":"2019-11-14T10:56:34Z","timestamp":1573728994000},"page":"1977","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The Effects of Helmet Therapy Relative to the Size of the Anterior Fontanelle in Nonsynostotic Plagiocephaly: A Retrospective Study"],"prefix":"10.3390","volume":"8","author":[{"given":"Do Gon","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu 702701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joon Seok","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu 702701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu 702701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung Dug","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu 702701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7359-3044","authenticated-orcid":false,"given":"Ho Yun","family":"Chung","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu 702701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byung Chae","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu 702701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kang Young","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu 702701, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"877","DOI":"10.1542\/peds.97.6.877","article-title":"Observations on a recent increase in plagiocephaly without synostosis","volume":"97","author":"Kane","year":"1996","journal-title":"Pediatrics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"e72","DOI":"10.1542\/peds.110.6.e72","article-title":"Incidence of cranial asymmetry in healthy newborns","volume":"110","author":"Peitsch","year":"2002","journal-title":"Pediatrics"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1097\/00006534-199289010-00005","article-title":"Frontal plagiocephaly: Synostotic, compensational, or deformational","volume":"889","author":"Bruneteau","year":"1992","journal-title":"Plast.
