Outfracture of the inferior turbinates during superior repositioning Le Fort I osteotomy with cone-beam computed tomographic analysis of the volume of the nasal cavity.

We have investigated the volumes of the nasal cavities of 35 patients treated with superior repositioning Le Fort I osteotomy by analysing cone-beam computed tomography (CT) data with a 3-dimensional reconstruction program to correlate changes in the volume of the nasal cavity that were associated with the maxillary superior repositioning and the role of outfracture of the inferior turbinates. The patients were treated at the Pusan National Dental Hospital during the 14-month period January 2011-March 2012..
