Immobilization
of unilateral(right) lambdoid suture was produced
in 9-day-old rabbits to determine its effect on
subsequent craniofacial growth. The suture was immobilized
by the topical application of methyl-2-cyanoacrylate
adhesive, subsequent growth effects on the cranial
vault, cranial base and facial skeleton were assessed
by serial radiographic cephalometry. The statistically
significant results(p<0.05) were.
1.
The growth of immobilized lambdoid suture
was decreased accompanying compensatory growth at
coronal suture bilaterally.
2.
The length of anterior and posterior cranial base
was increased.
3.
Anterior midfacial height was increased.
4.
Lower midfacial angle(angular relationship of cranial
base to lower midface) was decreased.
With
the view of above findings, it is clear that restricted
growth was seen at unilateral lambdoid suture
accompanying compensatory growth at coronal suture
and resulted in altered cranial base and facial
growth.
