As
the traffic accident and occupational accidents
increase, the pure blow out fracture has been increased.
If we could know the prognostic information of the
pure blowout fracture according to the fracture
sites. it would be of benefit in consulting the
patients preoperatively and in planning the treatment.
In
this study we defined the posterior wall fracture
as that extending 2 cm from orbital rim and the
anterior wall fracture as that presenting within
2 cm from orbital rim. These fractures were individually
classified into inferior wall fractures, medial
wall fractures, and combined inferior and medial
wall fractures, based on the operative finding and
the preoperative CT scanning. We experienced 76
cases of pure blowout fracture patients underwent
surgical correction and followed up the subsidence
of diplopia and extraocular muscle limitation with
ophthalmic Hess test.
The
results obtained are as followings:
l.
Posterior wall fractures were improved more slowly
then anterior wall fractures.
2.
Combined inferior and medial wall fractures were
improved more slowly than isolated inferior wall
or medial wall fractures. These results may be related
to the difference of the traumatic forces and the
anatomical structure of the fracture sites. These
result inform the importance of accurate anatomical
reconstruction of fracture sites and can be used
as a prognostic information of the pure blow out
fractures.
