Reconstruction of large hypertrophic scar on trunk and thigh by means of liposuction technique

Abstract 

Objective

Hypertrophic scars on trunk and thigh are less important in function and appearance than those on face, neck, hand, foot and joint. However, patients suffer itching, pain and disfiguration. Thus far, neither non-surgical nor surgical methods treat these scars perfectly. This study reports on the application of liposuction technique to reconstruct these scars and reviews the outcomes.

Method

Between March 2000 and March 2008, we treated 26 hypertrophic scars on trunk and thigh (20 patients) using liposuction. Tumescent liquids were infiltrated and liposuction was performed in the areas of trunk and thigh where the scars located. Following scar excision, defects were covered by sliding flap created by liposuction. Incisions were closed without tension.

Results

Twenty-six hypertrophic scars were reconstructed in one stage by flaps of similar texture and colour in areas around the scars without wound dehiscence, infection, skin necrosis, sensory deficit, haematoma and seroma. The contours of liposuction areas were natural and even.

Conclusion

Large hypertrophic scar at sites rich in subcutaneous fat such as trunk and thigh can be reconstructed in one stage by liposuction technique, which is easy, safe, effective and economic. Although indications of liposuction scar reconstruction are strict, it is indeed a better option for appropriate cases.
