Purpose: Positional plagiocephaly is an acquired deformation of an intrinsically normal infant skull by sustained or excessive extrinsic forces. Non-surgical techniques include counter-positioning, supervised prone time and orthotic molding for more refractory cases. Long-term eects of positional plagiocephaly on development remain undened, and this study evaluated cosmetic and cognitive outcomes of plagiocephaly management. Method: Surveys were administered to parents of patients treated for positional plagio-cephaly through the Children’s Hospital of Eastern Ontario. Categorical responses inter-rogated cosmetic outcome, school performance, language skills, cognitive development and societal function. Pearson coecient analysis tested outcomes dependency on gender, age, and plagiocephaly side at the 0.05 level of signicance. Results: Eighty respondents (51 male, 29 female) were divided as 58 right- and 22 le-sided pathology. Positional therapy was uniformly applied, and a helmet orthosis was util-ized in 36 % of cases. Median follow-up age was nine years with normal head appearance in 75 % of cases. Only 4 % of parents and 9 % of patients observed signicant residual asymme
