The cohort was stratified by age. The cranial vault asymmetry index (CVAI) was calculated at the superior orbital rim. Asymmetry was categorized according to the following CVAI scores: mild (3.5%\u20137%), moderate (7%\u201312%), and severe (> 12%). Patients were grouped by age to assess PPP at different stages of head development: group 1, 2\u20135 months; group 2, 6\u201311 months; group 3, 12\u201323 months; group 4: 2\u20134 years; group 5, 5\u20138 years; group 6, 9\u201312 years; and group 7, 13\u201318 years. Patients with a history of shunted hydrocephalus, craniosynostosis, skull surgery, or radiographic evidence of intracranial trauma were excluded.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n The overall cohort prevalence of PPP was 24.8% (354 patients). PPP prevalence was higher among younger patients from groups 1\u20133 (40.4%, 33.5%, and 0.8%, respectively). There was a continued decline in PPP by age in groups 4\u20137 (26.4%, 20%, 20%, and 10.8%, respectively). Mild cranial vault asymmetry was noted most often (78.0%, 276 patients), followed by moderate (19.5%, 69 patients) and severe (2.5%, 9 patients). There were no patients in group 6 or 7 with severe PPP.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n PPP is prevalent in pediatric populations and most commonly presents as a case of mild asymmetry. Although there was an overall decline of PPP prevalence with increasing age, moderate asymmetry was seen in all age groups. No patients in the cohort had severe asymmetry that persisted into adolescence.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2019.12.peds19651","type":"journal-article","created":{"date-parts":[[2020,3,6]],"date-time":"2020-03-06T10:11:54Z","timestamp":1583489514000},"page":"514-518","source":"Crossref","is-referenced-by-count":16,"title":["Positional posterior plagiocephaly: a single-center review"],"prefix":"10.3171","volume":"25","author":[{"given":"Ranbir","family":"Ahluwalia","sequence":"first","affiliation":[{"name":"Surgical Outcomes Center for Kids, Monroe Carell Jr. Children\u2019s Hospital at Vanderbilt, Nashville, Tennessee;"},{"name":"Florida State University College of Medicine, Tallahassee, Florida;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chelsea","family":"Kiely","sequence":"additional","affiliation":[{"name":"Surgical Outcomes Center for Kids, Monroe Carell Jr. Children\u2019s Hospital at Vanderbilt, Nashville, Tennessee;"},{"name":"Cornell University Department of Neurobiology, Ithaca, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jarrett","family":"Foster","sequence":"additional","affiliation":[{"name":"Surgical Outcomes Center for Kids, Monroe Carell Jr. Children\u2019s Hospital at Vanderbilt, Nashville, Tennessee;"},{"name":"University of South Carolina School of Medicine, Columbia, South Carolina; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Gannon","sequence":"additional","affiliation":[{"name":"Surgical Outcomes Center for Kids, Monroe Carell Jr. Children\u2019s Hospital at Vanderbilt, Nashville, Tennessee;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alyssa L.","family":"Wiseman","sequence":"additional","affiliation":[{"name":"Surgical Outcomes Center for Kids, Monroe Carell Jr. Children\u2019s Hospital at Vanderbilt, Nashville, Tennessee;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chevis N.","family":"Shannon","sequence":"additional","affiliation":[{"name":"Surgical Outcomes Center for Kids, Monroe Carell Jr. Children\u2019s Hospital at Vanderbilt, Nashville, Tennessee;"},{"name":"Department of Neurological Surgery, Vanderbilt University Medical Center, Nashville, Tennessee"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher M.","family":"Bonfield","sequence":"additional","affiliation":[{"name":"Surgical Outcomes Center for Kids, Monroe Carell Jr. Children\u2019s Hospital at Vanderbilt, Nashville, Tennessee;"},{"name":"Department of Neurological Surgery, Vanderbilt University Medical Center, Nashville, Tennessee"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Am Fam Physician","first-page":"1953","article-title":"Diagnosis and management of positional head deformity","volume":"67","author":"Biggs WS","year":"2003","unstructured":"Biggs WS: Diagnosis and management of positional head deformity.
