Background: Midface advancement is a keystone intervention in the treatment plan of syndromic hypoplasia of the midface. Although earlier authors had been using a combination of smaller incisions to acquire enough access to perform the different osteotomies, Tessier popularized the bicoronal incision. This approach can be time-consuming however and leaves an ear-to-ear scar. The authors describe an endoscopically assisted piezo-electric Le Fort III osteotomy performed through minimal invasive access. The cutaneous incision was limited to a single-short mid-glabellar vertical scar (8 mm) to perform the nasofrontal and septum osteotomy. Further osteotomies are performed through a 1.5 cm intraoral incision and a transconjunctival approach with a retrocaruncular extension. A lateral canthotomy was avoided to lower the risk of postoperative eyelid malposition.
Methods: A feasibility study using 2 fresh nonfrozen cadaver heads.
Conclusion: The minimally invasive Le Fort III approach is feasible and efficacious for clinical use in a cadaveric setup.
