  • Title: [Endoscopically assisted Le Fort 1 osteotomy: a study in human cadaver heads].
    Author: Rohner D, Yeow V, Hammer B.
    Journal: Mund Kiefer Gesichtschir; 2003 Jan; 7(1):14-8. PubMed ID: 12556980.
    Abstract:
    METHODS AND RESULTS: Endoscopically assisted Le Fort 1-osteotomy was performed in a cadaver study with six human skulls. Vertical incisions were used to approach the maxilla using the endoscope. The bone cuts could be carried out with a 4-mm osteotome preserving the buccal mucosa. The downfracture of the maxilla was accomplished without damaging the descending palatal arteries, which could be verified endoscopically. Rigid fixation was performed using 1.5-mm titanium plates (Synthes, Mathys AG, Bettlach, Switzerland) and self-drilling screws. DISCUSSION: This cadaver study showed that the Le Fort 1 osteotomy could be carried out through limited approaches using endoscopic techniques and self-drilling fixation tools. Further experimental work and improvements will help to introduce this technique into clinical application.
