The DIGITAL CRANIOMETER

Baby Skull's digital craniometer is a measuring instrument designed to diagnose and monitor the evolution of cranial asymmetries (Plagiocephaly and Brachycephaly) in children.

The recommendations of the High Authority for Health (March 2020) encourage health professionals to take "anthropometric measurements useful for measuring the evolution of cranial deformities in babies".

The craniometer is in the form of a design and ergonomic compass.
Its large LED screen allows quick and ultra-precise measurement.
3 units of measure: mm / inch / fraction
* supplied with a 3V CR2032 battery and a pair of protective caps

Used by specialized professionals: pediatrician, osteopath, physiotherapist, chiropractor…

Numerous studies have demonstrated the reliability of this instrument using the intra-class correlation coefficient, associated with a high confidence interval.

The reliability of the craniometer is excellent in intra-examiner.

Reminder on the measures of the Cranial Indices

Taking measurements of the cranial indices can objectively quantify the deformation of a baby's skull.

These cranial indices are of major interest in diagnosing, evaluating and guiding the treatment of Plagiocephaly and other cranial deformations.

How to measure Plagiocephaly?

To obtain cranial asymmetry (Plagiocephaly), calculate the CVA (Cranial Vault Asymmetry) score by measuring the difference between the diagonals of the cranial vault.

Plagiocephaly (CVA) = A - B (in mm)

Plagiocephaly classification:

Light: from 0 to 6 mm

Moderate: 6 to 12 mm

Severe: more than 12 mm

* between 0 to 3mm, Plagiocephaly can be considered as Normal

CVAI: Cranial Vault Asymmetry Index

The CVAI is the cranial asymmetry score divided by the larger of the two diagonals measured.
It is very useful because it remains proportional to the growth of the skull and is independent of the age of the baby

How to measure Brachycephaly?

To measure posterior flattening (Brachycephaly), calculate the CI (Cranial Index) ratio between width (ML) and length (AP).

Brachycephaly (CI) = (ML / PA) x100 (in%)

 

Brachycephaly classification:

Light: 85 to 90%

Moderate: 90 to 95%

Severe: more than 95%

* between 78 and 84% the Cranial Index is considered as Normal
