Sutures of NSOP evaluated for:
- focal fusion
- endocranial heaping/ridging
- narrowing
- perisutural thinning
- sclerosis
- change in orientation: overlapping to end-to-end and were compared to sutures of LC (p values)
NSOP Focal-Skip Fusion: 25% (p=0.308)
NSOP sutures demonstrated areas of skip fusion 25% of the time.
NSOP Endocranial Heaping: 78% (p=0.313)
Ectocranial Heaping: 0% (p=<0.001)
No ectocranial heaping was noted in NSOP.
NSOP Suture Narrowing: 63% (p=0.008)
NSOP sutures demonstrated sutural narrowing in 63% 0f cases.
NSOP Sclerosis: 16% (p=0.319)
Sutural sclerosis was noted in 16% cases.
NSOP Change in Suture Orientation: 63% (p=0.001)
Sutures of NSOP demonstrated a change in suture orientation from overlapping to end-to-end morphology.
NSOP Perisutural Thinning: 78% (p=0.313)
Subarachnoid Spacing: 47%
Ipsilateral increase in subarachnoid spacing was noted in 47% of NSOP and in no cases of OP.
Suture Morphology: NSOP
- Comparing affected to contralateral non-affected "control" suture
- Significant difference (p<0.05):
- overlapping
- endocranial ridging/heaping
- perisutural bone thinning
Cranial Morphology: NSOP
- Ipsilateral occipital flattening in all cases (100%)
- Ipsilateral frontal bossing (85%) (p=0.012)
- Contralateral occipital bossing (95%) (p=0.003)
Suture Morphology: LC
- Near complete obliteration 100% (p=<0.001)
- Endocranial heaping: 100% (p=0.313)
- Ectocranial heaping: 100% (p=0.001)
Cranial Morphology: LC
- Ipsilateral occipital flattening: 100%
- Compensatory ipsilateral mastoid bossing: 100% (p=<0.001)
- Contralateral parietal bossing: 100% (p=0.003)
- Trapezoid vertex morphology
Midline Cranial Base Deviation Angle
- Significant difference was found
- LC: Angles were greater and represented a larger deviation from
mid sagittal cranial base axis
- average 10.3° (range 0-15°)
- NSOP
- average 4.1° (range 0-9°)
- p=0.02
Petrus Ridge Angle
- Significant difference between affected and non affected side also between the affected sides in NSOP and LC
- NSOP
- affected: av. 121.8° (range 117-1270)
- non-affected: av. 125.8° (range 117-1340)
- p=0.0016
- LC
- affected: av. 115.7° (range 112-1200)
- non-affected: av. 132.0° (range 128-1400)
- p=0.0156
- NSOP vs. LC
Ear Position
- Vertex view
- LC
- anterior 14%
- symmetric 86%
- NSOP
- anterior 85%
- symmetric 15%
