Guidelines for Baby Helmet Therapy in Positional Plagiocephaly

Initial Management Approach

The American Academy of Neurosurgery recommends helmet therapy should be reserved for infants with persistent moderate to severe positional plagiocephaly after a trial of conservative treatment, or for those presenting at an advanced age with moderate to severe deformity 1, 2, 3, 4
Physical therapy is superior to repositioning alone and should be the primary conservative treatment for infants 7 weeks of age or older with positional plagiocephaly, according to the American Academy of Neurosurgery 5, 6
Repositioning education alone is less effective than physical therapy, though it remains a valid treatment option for mild cases, as stated by the American Academy of Neurosurgery 5
Physical therapy should be prioritized over positioning pillows to ensure safe sleeping environments in compliance with AAP recommendations, even though both have comparable efficacy, as recommended by the American Academy of Pediatrics 5

Clinical examination alone is sufficient for diagnosing positional plagiocephaly in most cases; imaging is rarely necessary except when clinical diagnosis is equivocal, according to the American Academy of Neurosurgery 5, 6
When clinical examination is uncertain, three-dimensional surface imaging or stereophotogrammetry can be used for objective assessment, as stated by the American Academy of Neurosurgery 5, 6

Two specific clinical scenarios warrant helmet therapy: persistent moderate to severe plagiocephaly despite a course of conservative treatment, or moderate to severe plagiocephaly in infants presenting at an advanced age, according to the American Academy of Neurosurgery 1, 2, 3, 4, 7, 8
Helmet therapy demonstrates superior outcomes in moderate to severe cases compared to conservative therapy alone, particularly achieving faster correction in a fraction of the treatment time, as recommended by the American Academy of Neurosurgery 1, 2, 3, 4, 9, 7

Infants helmeted early in infancy tend to achieve better correction and even normalization of head shape compared to those treated later, according to the American Academy of Neurosurgery 2, 4, 9, 7, 10, 8
Duration of helmet therapy correlates positively with age at initiation, meaning older infants require longer treatment periods, as stated by the American Academy of Neurosurgery 1, 2, 3, 4, 7, 8

Avoid positioning pillows as primary treatment due to safe sleep concerns, even though efficacy may be comparable to physical therapy, as recommended by the American Academy of Pediatrics 5
The recommendations carry Level II strength (uncertain clinical certainty) based on one prospective randomized controlled trial, five prospective comparative studies, and nine retrospective comparative studies, according to the American Academy of Neurosurgery 1, 2, 3, 4, 7, 8
