Dynamic analysis of maxillary perfusion during Le Fort I osteotomy using indocyanine green

The aim of this study was to evaluate the dynamic perfusion of the maxilla during various stages of a Le Fort I osteotomy using indocyanine green (ICG) dye angiography. This was a retrospective evaluation of patients who underwent a Le Fort I osteotomy. ICG was used to assess perfusion at specific time points during the procedure. Twenty-four patients underwent a Le Fort I osteotomy with dynamic perfusion ICG angiography. Statistically significant differences in perfusion were noted at all three locations assessed between preoperative (T0), post down-fracture (T1), and postoperative (T2) time points.
