When a baby is diagnosed with Deformational Plagiocephaly, it is important to determine whether or not the baby will benefit from Cranial Remodel Band or Helmet.
So what is the Cephalic Index? The Cephalic Index, also referred to as cranial ratio or cephalic ratio is the measurement that will be used to categorize your infants head shape.
CI = width ÷ length x 100 or CI = (Left/Right) ÷ (Front/Back) x 100
Scale for Cephalic Index (CI)
Normal: 75 – 90 mm
Mild: 91 – 93 mm
Moderate: 94 – 97 mm
Severe: >97 mm
Normocephaly or plagiocephaly = CI >76%-<90%
Brachycephaly = CI >90%
Dolichocephaly = CI <76%
Scale for Measuring Plagiocephaly
Normal head shape: 0 – 4 mm
Mild Plagiocephaly: 5 – 9 mm
Moderate Plagiocephaly: 10 – 15 mm
Severe Plagiocephaly: >15 mm
Cranial vault asymmetry also referred to as diagonal difference, oblique diagonal difference, or transcranial difference. CVA is the difference between 2 diagonal measurements. *** It is important to note that CVA will be symmetric in brachy-, and dolichocephaly.
These numbers may seem confusing but this has proven to greatly assist in the monitoring of children with any skull shape concerns.
