Evaluation of positional cranial deformities: the non-expert perspective

Area of Science:

• Pediatrics
• Craniofacial Surgery
• Public Health

Background:

• Positional cranial deformity (PCD) is a debated topic, with varying opinions on the necessity of interventions like helmet therapy.
• Specialist views differ on whether fears surrounding PCD are exaggerated or if helmets are essential for treatment.

Purpose of the Study:

• To assess laypeople's perception of positional cranial deformities.
• To determine laypeople's threshold for recommending treatment for PCD.
• To evaluate the clinical relevance of PCD based on public opinion.

Main Methods:

• Interviewed 395 unaffected laypeople regarding their opinions on PCD.
• Presented standardized photographs of 10 children with varying degrees of PCD in a randomized order.
• Defined 'obviously abnormal' as perceived by at least 50% of respondents; set therapeutic recommendation cut-off at 25%.

Main Results:

• Laypeople perceived all heads above established reference values (cranial index: 85%; cranial vault asymmetry index: 3.5%) as significantly abnormal.
• A need for treatment was identified by laypeople for plagiocephaly (51.1-72.9%), brachycephaly (59.5-62.0%), and combined deformities (37.2%).
• Even very mild deformities were perceived as conspicuous and treatable by laypeople.

Conclusions:

• The study confirms existing reference values for PCD.
• Laypeople's perception highlights the clinical relevance of PCD, suggesting it should not be underestimated.
• Regular treatment, including conservative methods or head orthoses, is recommended based on deformity severity.
