Jesse Taylor, MD, Chief of Plastic and Reconstructive Surgery at Children’s Hospital of Philadelphia, talks about positional plagiocephaly, a common condition in infants. He discusses the Back to Sleep campaign's impact on its prevalence and differentiates it from craniosynostosis. Dr. Taylor highlights risk factors and management strategies, stressing the importance of early intervention and parental concerns about aesthetics. The conversation also covers critical assessment techniques to ensure effective monitoring in infants.
The rise in positional plagiocephaly, linked to the Back to Sleep campaign, highlights the trade-off between infant safety and head shape concerns.
Clinically differentiating positional plagiocephaly from craniosynostosis is essential, as they present distinct head shapes and developmental timelines.

Increasing Incidence of Positional Plagiocephaly
The prevalence of positional plagiocephaly has risen significantly, primarily attributed to the back-to-sleep campaign designed to enhance infant safety. While this campaign effectively reduces sudden infant death syndrome (SIDS), it has resulted in more babies developing flat head syndrome. Evidence indicates that children aged two to seven months are particularly at risk, with incidence rates soaring to as high as 60%. This phenomenon raises concerns about whether flat heads might become a common feature of this generation's infants, prompting discussions on potential shifts in sleep positioning recommendations.
Differentiating Between Plagiocephaly and Craniosynostosis
Positional plagiocephaly is markedly more common than craniosynostosis, with incidence rates for craniosynostosis averaging one in 3,000 live births. Clinically, distinguishing between the two conditions relies on head shape observations; plagiocephaly typically presents a parallelogram shape due to unilateral flattening, while craniosynostosis often exhibits a trapezoidal appearance. The timing of head shape abnormalities is also crucial; plagiocephaly generally develops postnatally, whereas craniosynostosis is evident at birth. Additionally, torticollis is frequently associated with plagiocephaly, complicating clinical assessments and emphasizing the need for professional evaluations in ambiguous cases.
Helmet Therapy Efficacy and Considerations
Helmet therapy for positional plagiocephaly is reported to be effective around 95% of the time, with low risks of complications when used properly. Most children wear helmets for 23 hours a day over a period of four to six months, but there are concerns regarding pressure ulcers, especially in warmer months when sweat accumulation can heighten risks. The efficacy of helmeting tends to diminish after the first birthday as cranial bones become less malleable, underscoring the importance of timely referrals for potential intervention. Although recent research suggests a correlation between severe plagiocephaly and neurodevelopmental delays, general positional plagiocephaly is primarily viewed as a cosmetic issue, with natural improvement expected over time.
