How often does plagiocephaly occur?
Due to many factors, the incidence of plagiocephaly has dramatically increased in the last 20 years. While the numbers vary depending on the research study, the most commonly cited incidence is one out of 30 infants. It should be noted that many recent reports published in 2008 and 2009 have cited this number at 1 in 15 and most recently 1 in 6.
