The relationship between the expanded surface-area of tissue expander and the injected saline volume
Objective By measuring the expanded surface-area of tissue expander and the injected saline volume,their relations were primarily explored.Methods Seven expanders of different volumes were embedded into teh faces, shoulders,chests and hips of seven patients The method of converting the tridimensional surface to a plane for measuring expanded skin area with computer aid was adopted so as to analyze the relations between the expanded surface-area and the injected saline volume. Results The expanded surface-area enlarged as the injected saline volume increased, but when the injected saline volume reached to 130%～180% of the volume of the expander, the surface-area of tissue expansion inclined to a platform. Conclusion The expanded surface-area is not unlimited. When the injected saline volume reaches to 130%～180% of the designed volume of expanders,inspite of an increase, the surface-area will not enlarge any more.
