BackgroundIn patients with Pfeiffer syndrome, several corrections are required to correct facial retrusion, maxillary deficiency, or even hypertelorism. The frontofacial monobloc advancement (FFMA) and the facial bipartition (FB) are the gold standard surgeries. We present the correction of this deformity using a simultaneous computer-assisted FFMA and FB.MethodsThe 3-dimensional surgical planning defined the virtual correction and bone-cutting guide in view of the FFMA and FB. Coronal and intraoral approaches were combined to perform the osteotomies. Four internal distractors were also placed for the postoperative distraction osteogenesis.ResultsWe reported 2 cases of computer-assisted surgery with satisfying outcomes. The sagittal deficiency (fronto-facial retrusion) was corrected by FFMA and the transversal abnormality (i.e., hypertelorism and maxillary deficiency) by the FB, then followed by an internal distraction osteogenesis.ConclusionsComputer-assisted surgery is helpful and a reliable option for the management of complex faciocraniosynostosis such as hypertelorism and frontofacial retrusion.Copyright © 2022 Elsevier Inc.
