[Tissue expansion under the cicatrix].
OBJECTIVE
To investigate a more simple and effective method to repair cicatrix by tissue expansion.


METHODS
The dilator with the capacity of 80 - 500 ml was implanted into the subcutaneous pocket under the cicatrix. After dilating for one to two months, the dilator was taken out and the wound surface of the cicatrix was removed. The expanded skin flap was advanced or rotated to cover the defects. The procedure was used on 203 cases.


RESULTS
The dilatation was achieved successfully in all the cases, followed by cicatrix removing and repair. The incision scar was not noticeable.


CONCLUSIONS
Tissue expansion under the cicatrix has the advantages of safety, less trauma and less extra incisions. It is a reasonable choice to obtain more flexible surgical designs and more economical skin flap applications. It is suitable for most of the treatment for cicatrix.
