Abstract
The aim of this study is to present an oral device that improves splanchnocranium
stability after osteodistraction in children treated for correction of
craniofacial malformations. When removal of the distraction device before the end
of the treatment is necessary, the reposition of a new fixation system might not
be possible. In these cases, regrown bone is immature, and relapse of
malformation occurs frequently. We have been treating these cases by the
application of an oral device named Maxillary Advancement Contention (MAC). MAC
is used in every patient when any complication interrupts the protocol of
osteodistraction before the end of the stabilization time. The device is placed
immediately after the removal of the distraction device and left in place for at
least three months. We used MAC in six children surgically treated for correction
of craniosynostosis with facial or craniofacial advancement. To establish the
relapse of malformation we analyzed relations Sella-Nasion-Orbitale (SNOr) and
Sella-Nasion-A point (SNA) angles before application of the MAC and after one
year. The analysis of stability was excellent in every patient. This device might
help, with a minimally invasive procedure, to maintain the obtained advancement
allowing stabilization of the regrown bone.
