Abstract:
Objective: To establish the model of palatine mucoperiosteal expansion and observe a new possible treatment approach to soft tissue defect of cleft palate. Methods: Expanders of 10ml were implanted beneath the palatine mucoperiosteum in 4 dogs and injected 1.0ml 0.9% NaCl at the same time. 20 days after the placement of the expander, the expander was expanded by 1.0-1.5ml every 7 days again. The dogs were killed after the expanders reached their capacity. All the specimens were performed histomorphometric and histological examinations. Results: Histological results showed the increase in the layer of cell and the number of collagen fibra and blood vessel. All the specimens of expanded tissue showed the formation of extra palatine mucoperiosteal tissue. Conclusion: Expansion technique is able to form extra palatine mucoperiosteal tissue,which could be a new restoration approach to soft tissue defect of cleft palate and others.
