[An experimental study of 3-dimension zygomatic suture extension for suture osteogenesis].

Objective: To explore a methods of 3-Dimension expansion of zygomatic suture in a goat model.

Methods: Seven goats were used in this study. The 3-D extensive applicator was designed and used to extend the zygomatic suture of the goats by placing it in the zygomatic bone through an infraorbital incision. Ten days after the first operation, it was gradually extended on a speed of 0.09 cm/d for 7 days. The zygomatic movement and the osteogenesis of the suture was evaluated in two weeks.

Results: The zygomatic bone was extended for 0.6 cm long in average, and the osteogenesis was also shown significantly in the suture.

Conclusion: The above mentioned technique could be a safe and effect method to be applied for the zygomatic extension.
