STARscanner Report with explanation of results

(Level 3 measurements)

 

  • Cephalic Ratio = Cranial Breadth / Cranial Length.  An ideal ratio would be 0.78 or 78%.  Brachycephaly Severity - normal - 73-83%; moderate - 83.1% to 87.9%; severe - 88% and higher.  Scaphocephaly Severity - normal - 73-83%; moderate - 68.1% to 72.9%; severe - 68% and below.  Your son is 97.3%

·       Radial Symmetry Index (RSI) = from the front of the head, 15° segments are measured and added.  The addition of the right side segments is subtracted to the addition of the left side segments. An ideal ratio would be left side – right side = 0 (<30 mm normal) Your son is 65.1

·       Oblique Cranial Maximum and Minimum = Ideally one is looking to have the maximum line vertical and the minimum line horizontal. 

·       Oblique at 30 deg (US1 and US2) = Length of diagonal taken at 30° on each side (30° corresponds to the corner of the eye).  The subtraction of US1 and US2 gives an indication of the asymmetry of the head.  An asymmetry between 0-3 mm is normal; <6 mm is very mild; 6-10 mm is mild; 10-15 mm is moderate; 15+ mm is severe Your son is 14.2 mm (159.9-145.7)

·       Q1, Q2, Q3, Q4 volumes: Draws vertical and horizontal lines centered on middle point of head.  Measures volume of each corner starting front left, then front right, back right and back left.

·       Anterior Symmetry Ratio: looks at front of head and divides front left volume with front right volume. An ideal ratio would be 1 Bradley - 0.795

·       Posterior Symmetry Ratio: looks at back of head and divides back right volume with back left volume.  An ideal ration would be 1 Bradley - 0.9981

·       Overall Symmetry Ratio: Divides left side with right side.  An ideal ratio would be 1 Bradley - 0.888

·       Upper facial left and upper facial right: Measures the length between the centre of the front to each left and right ear.  This corresponds to a cranial bone and determines the position of the ear.

·       Upper Facial Symmetry Ratio: Divides Upper Facial Right with Upper Facial Left. An ideal ratio would be 1  Bradley - 0.941

·       Cranial Vault Asymmetry Index (CVAI)the percentage difference in plagio, (100%-(US1/US2)).  0-3 mm normal

·       Ear Offset - this number seems to be very subjective because the ortho places stickers near the ears that the machine picks up to take this measurement.  If they are placed differently each time the number will come out differently

Subject: [SPAM] [Plagio] Confused on the starscanner info

 

Hi,
My son Bradley has his first appointment on the 8 of this month and
will be getting his starband on tues the 22nd. But I am still
confused when it comes to the numbers and results of the scan. this
is what it says:

Circumference (mm) 471.3
Cranial Breadth(M-L) (mm) 147.6
Cranial Length(A-P) (mm) 151.6
Cephalic Ratio(M-L/A-P) 0.973
Radial Symmetry Index(RSI0 (mm) 65.1

Oblique Diagonal 1 at -30.0 deg (mm) 159.9
Oblique Diagonal 2 at 30.0 deg (mm) 145.7
Oblique Cranial Minimum at 63.7 deg (mm) 140.4
Oblique Cranial Maximum at -33.9 deg (mm) 160.3

Q1 Volume (A/L) (cc) 256.5
Q2 Volume (A/R0 (cc) 203.8
Q3 Volume (P/R) (cc) 259.2
Q4 Volume (P/L) (cc) 254.3
Anterior Symmetry Ratio 0.795
Posterior Symmetry Ratio 0.9981
Overall Symmetry Ratio 0.888

Upper Facial Left (TrL-Se) (mm)94.1
Upper Facial Right (trR-Se) (mm) 100.0
Upper Facial Symmetry Ratio 0.941

Ear Offset (mm) 8.4
Cranial Base WIdth (TrL-TrR) (mm) 138.7
Vertex Hight (Lev0-Lev10) (mm) 104.9

Can anyone please help me read this and tell me what it says. Or give
me an idea of what they usual look at. I am just really confused. All
I know is that somewhere in all those numbers it is suppose to mean
that he is at a 14mm which is moderate plagio. But I would like to
know how it says that and what all rest of it means. So if anyone or
everyone can please help i would appreciate it.
Thanks in advance
Kristen
Bradley 8 1/2 months Moderate plagio
