Many authors reported the etiology of hypoplasia of the nasomaxillary complex as
trauma, infection, underdevelopment. To correct these deformities, Le Fort II Osteotomy
and its modification has been popularly applied. This method enabled total advancement
of nasomaxillary complexes and acquirememt of midfacial esthetics. But it has some
limitations such as various occlusal deviation or lateral shifting of nasomaxillary complex
in case of nasomaxillary retrusion.
We grouped these patients as follows :
1. Nasomaxillary retrusion without shifting of nasomaxillary complex
(1) Anteroposterior deviation of occlusal plane
(2) Lateral deviation of occlusal plane(including canting)
(3) Supero-inferior deviation of occlusal plane
(4) Combined disturbance of occlusal plane without shifting of nasamaxillary complex
2. Lateral shifting of nasomaxillary complex with or without deviation of occlusal plane
We performed Le Fort II and I combined osteotomy on eleven cases of midfacial
deformity from June 1994 to July 1997 and in most of the cases, followed up maximum
36 months and could acquire positional stability and improvement of facial eathetics.
