Background:
For surgical closure of large skin defects, elaborate reconstructive plastic surgery or other methods such as internal subcutaneous balloon tissue expanders are required in order to avoid tension on the closure margins. Here we point to the benefits and disadvantages of an improved and simple method of secondary wound closure by secondary sutures.
Patients And Methods:
We employed a system called External Tissue Extender (ETE), which consists of silicone strings and plastic stoppers pulling the corresponding surgical sites together and evenly distributing the tension. Possible indications in dermatologic surgery and our experiences with this technique are outlined.
Results:
Implantation and handling of the ETE are very easy and fast. The functional results are good and the cosmetic outcome satisfactory. More invasive surgical procedures can be avoided by using this method. A major disadvantage is the possibility of developing necrosis under the plastic stoppers.
Conclusion:
According to our experience, the ETE is a useful alternative indicated in certain dermatosurgical situations.
