Table 1 Description of the fusion of the spheno-occipital synchondrosis scoring
Stage | Status | Description |
|---|---|---|
1 | Un-fused | Opened entirely with no sign of closure or presence of bone in the gap between the endocranial and ectocranial borders |
2 | Partial-fused | Fused endocranially but not more than half the length of the synchondrosis (Fusing endocranially, ≤ 50%) |
3 | Semi-fused | Fusing ectocranially with more than half the length of the synchondrosis but without fusing of the inferior (ectocranial) border. (Fusing ectocranially, > 50% and less than 100% fusion) |
4 | Complete fusion | Fused entirely with normal bone appearance throughout the synchondrosis, but a fusion scar may exist |
