What causes deformational Plagiocephaly? Prolonged pressure the skull in a particular position SIDS protocols “Back to sleep” Torticollis – a tightening of the neck muscles Macrocephaly Child resistant to ‘tummy time’ / muscle weakness Lack of education of prevention methods Utero constraints eg multiple births, insufficient pelvis
The expanding brain applies an externally directed force, with the brain capable of extreme plastic deformation with no loss of function or intellect if volume is not reduced
![Page 13: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/13.jpg)
Sleeping Position
• 1992 AAP recommended infants sleep supine/side to reduce SIDS risk
• Revised 1996 – no sidelying sleeping
• Victorian statistics:
1989 513 SIDs deaths/year
2000 140 SIDS deaths/year
![Page 14: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/14.jpg)
Incidence
SIDS reduced significantly since inception of ‘Back to Sleep’ campaign (up to 40%) (Task Force on Sudden Infant Death Syndrome, 2005; Saeed et al., 2008; Xia et al., 2008; Losee & Mason, 2005).
Dramatic increase (10-48%) in incidence of plagiocephaly since “Back to Sleep” campaign (Saeed et al., 2008; Habal et al., 2004; Persing et al., 2003; Xia et al., 2008).
13-15% singletons have some flattening Right side more common 1.3% incidence torticollis Deformity persists in 30% at 2 years
![Page 15: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/15.jpg)
Risk factors:found repeatedly
• Male• First born• Multiple pregnancy• Prematurity• Oligohydramnios• Supine sleeping• < 5 mins tummy time/day• Delayed motor milestones• Preferred head orientation for sleep at 6 weeks• Positioning to same side for all bottle feeds
![Page 16: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/16.jpg)
Decreased Prone Play
• Decreased awareness of the importance of supervised ‘tummy time’, extended time on back
• WHY?• Parental fears• Infant intolerance
![Page 17: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/17.jpg)
Treatment of Plagiocephaly
Wait and See! If torticollis present, treat with
physiotherapy/gentle stretching Counter positioning
• Changing the forces on the head by altering the lying position
Cranio-reshaping helmet therapy• Fitting a custom made helmet which is worn for 23/34
hours a day until improved cosmesis is achieved
![Page 18: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/18.jpg)
Classifications• Macdonald 1969 gave 3
classifications:• Sternomastoid tumour group (42.7%)
• palpable mass present
• Muscular torticollis group (30.6%)• tight SCM but no palpable mass• Reduced active/passive ROM
• Postural torticollis group (22.1%)• no palpable mass or tightness• Full active/passive ROM
Cheng 2000
![Page 19: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/19.jpg)
Congenital Muscular Torticollis (CMT)
• CMT usually presenting with unilateral tightness of the sternocleidomastoid (SCM) muscle (Luther, 2002)
• Characterised by lateral flexion to the affected side and rotation away from the affected side
![Page 20: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/20.jpg)
Physiotherapy Rx• Goals of Physiotherapy:
• increase PROM• increase AROM• Improving facial and cranial
symmetry• Encourage gross motor
development
• Education, Stretching, Counter
positioning techniques
including positions carrying
and for play
![Page 21: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/21.jpg)
Counter Positioning
• Parent education• Active and consistent
repositioning of infant during play to apply pressure to prominent part of the skull
• Use of passive devices to position baby, specially designed devices
![Page 22: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/22.jpg)
Counter positioning
Positioning, play and carrying techniques to encourage movement to ‘neglected side’ and lengthen tight muscles
![Page 23: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/23.jpg)
Variety of positions for play
• Supervised ‘tummy time’ whilst the infant is awake
• Head shape and motor development are affected by sleep and awake positions of infant
![Page 24: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/24.jpg)
Prevention is the key !
![Page 25: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/25.jpg)
Key Preventative Strategies
1. Early detection of torticollis & referral to Physiotherapy
2. Encourage prone & side-lying during supervised awake play periods several times per day
3. Nightly/weekly alternating head positioning during supine sleeping
4. Avoid prolonged repetitive positioning (e.g. Car seat carriers, buggies, baby swings & bouncers.
5. Regularly change position of cot in room or toys/mobiles around cot.
6. Counter positioning / alternating the orientation of infant in the cot
7. Alternating feeding positions.(Saeed et al., 2008; Task Force on Sudden Infant Death Syndrome, 2005; Neufeld & Birkett, 1999;
Persing et al., 2003; van Vlimmerman et al., 2008., Canadian Paediatric Society, 2001).

Assessment
• History• Examination• Severity scoring• Measurement• Closure of anterior fontanelle
• Range 4 to 18m
![Page 27: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/27.jpg)
Clinical Severity Score
![Page 28: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/28.jpg)

• Research into the effectiveness of conservative management is just beginning
• 3d Capture • Counterpositioning: initial treatment• Follow-up 3d review• Physiotherapy: if torticollis present• Orthotic management: for severe cases in older
infants (from 6/12 old)
RCH treatment model
![Page 30: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/30.jpg)
To treat or not to treat?
• Cosmetic condition• Studies have shown that helmets improve the
head shape• No study has been conducted to see if the
condition self corrects regardless of treatment• Who should we treat ?• Last resort when conservative management fails.
They are not an ‘easy’ option• Significant time and resource costs for health
services and families
![Page 31: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/31.jpg)
Indications for referral to RCH Deformational Plagiocephaly Clinic
• Failure of early treatment strategies• Severe deformity• Severe torticollis and restriction• Associated medical conditions
• Prematurity• Developmental delay
![Page 32: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/32.jpg)
Helmet Therapy
• Do not affect the growing brain• Not the easy option!• They are a significant cost in time and
resources for families• For most children they shouldn’t be
required
![Page 33: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/33.jpg)
RCH treatment protocol:
To qualify a child must:• Have a deformational score of 6 or greater on the
assessment sheet or• Score a 3 in a single deformation change• Be at least 6 months old• Have no craniosynostosis• Helmets do not treat torticollis!
![Page 34: Does my child have a “flat” head? Lloyd Ellis & Anna Noisette The Royal Children’s Hospital, Melbourne](https://reader037.vdocuments.site/reader037/viewer/2022110205/56649c815503460f949384e9/html5/thumbnails/34.jpg)

plagiocephaly to:
• Raise awareness• Early recognition• Early management• Prevention
• Raise awareness• Early recognition• Early management• Prevention
Further research required in:• Natural history of plagiocephaly• Severity rating of plagiocephaly• Objective outcome measures
