Surgical treatment of midface deformities.

Midface deformities may be treated either by osteotomies that advance the maxilla or by osteotomies that retract the mandible. A transfacial technique is presented by which the cheekbones, the infraorbital rim, and the superior dental arch are advanced. The indications for this intervention are more widespread than those for Le Fort I osteotomies or mandibular osteotomies. Postoperative complications and risks of recidivism are reduced for this method because of the use of small screw-on plates for frontomalar osteosynthesis. Fifty-two cases of osteotomy are presented with special consideration of problems caused by bone grafting and postoperative occlusion and with a discussion of the factors responsible for relapse.

[Mandibular osteosynthesis according to the Michelet technic. I. Biomechanical bases].

Experiments performed in collaboration with a group of engineers lead to following affirmations: - mandible's external cortex is strong enough to endure strains resulting from screws, - osteosynthesis plate must be screwed in high position, - the material elaborated according to biomechanical data appears constantly reliable despite more marked miniaturization and improved malleability.

[Mandibular osteosynthesis according to the Michelet technic. II. Presentation of new material. Results].

The purpose of this communication is: - To report the conclusions of a critical study realized in collaboration with a group of engineers and concerning some presently obtainable osteosynthesis materials. - To ascertain mechanical characteristics required by screws and plates used for this type of surgery. - To relate a 4 years experience concerning 130 osteosynthesis (32 performed with a new material worked out according to biomechanical data).
