Figure 4.3 The
superimposition of
radiographs of simi-
larly aged children,
one diagnosed with
Apert syndrome, the
other unaffected.
Figure 4.3a shows a
comparison of the
two forms based on
a sella-nasion
scheme. The com-
parison shown in
Figure 4.3b is based
on a sella-basion
scheme. Differences
in the two compar-
isons are obvious.
The choice of which
scheme is used
might ultimately
influence the plan-
ning of patient
treatment (following
Richtsmeier, 1986).
