PURPOSE: Frontonasal dysplasia or median cleft syndrome is a rare condition often associated with transverse maxillary deficiency for which facial bipartition is the proper surgical treatment. This technical note describes the use and efficacy of 3-dimensional virtual surgical planning and patient-specific cutting guides in facial bipartition.
MATERIALS AND METHODS: An 11-year-old boy presented with frontonasal dysplasia and a midline facial cleft.
RESULTS: Computed tomographic (CT) scan visualized an intercanthal distance of 40 mm and a maxillary width at the second molar level of 46.2 mm. The osteotomies, amount of bone removal, and movement of the osteotomized bone were planned virtually based on CT findings: the intended postoperative intercanthal distance and maxillary width were 25.5 and 49.6 mm, respectively. Customized cutting guides and titanium miniplates were manufactured. Postoperative CT scan showed an intercanthal distance of 25.5 mm and a maxillary width of 49.7 mm.
CONCLUSION: The intercanthal distances and maxillary widths were similar between the simulation and postoperative CT images, confirming the accuracy and utility of computer-assisted surgery in facial bipartition.
