A concensus conference on the timing of facial osteotomies was held in
Jonkoping, Sweden. Seven teams consisting of a maxillofacial surgeon
and an orthodontist representing five countries discussed treatment pl
anning for young patients with maxillomandibular deformities with spec
ial emphasis on timing. Patients with severe syndromic facial deformit
ies were not considered. Consensus was reached that for most deformiti
es it is best advised to wait until growth has ceased, as determined b
y longitudinal cephalometric data. This rule is less tight for Angle C
lass II than for Class III cases. For asymmetries often there is still
not enough scientific evidence to obtain well-founded uniform agreeme
nt.
