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.
