[The importance of avoiding the use of rigid fixation in functional genioplasty]

This article presents a brief review of several principles which Delaire has shown to be important in both craniofacial growth and cranio-maxillofacial balance. In light of these events, we propose that the maxillofacial surgeon either avoids, if possible, the use of rigid fixation in functional genioplasty or that he removes the screws and plate at a later date. The specific patterns of bone apposition and resorption observed following functional genioplasty form the basis for this recommendation.
