ABSTRACT
BACKGROUND: Soft tissue expansion is a common technique for the regeneration of extra skin to repair skin defects. However, some warning signs like skin thinning and telangiectasia are often found during the expansion process, which indicates the skin flaps cannot be further expanded. These signs may result in the suspension of expansion or ultimately jeopardize the final outcome. Fat grafting is used to treat these potential complications and enable the continuation of the expansion procedure in some cases. In this study, we aimed to investigate the efficiency and safety of fat grafting in this process.
METHODS: The study was conducted on patients from January 2012 to December 2017 with warning signs of expansion treated with fat grafting (treatment group) or pause expansion (control group). Follow-u p data, such as expansion status, dermal thickness, telangiectasia, skin texture using volume assessment, B-mode ultrasound, and semiquantitative scoring, were collected.
RESULTS: A total of 67 expanded skin regions with warning signs were enrolled. The expansion fold increased 2.14-fold at 12 weeks after treatment compared with 0.74-fold in control (P=0.02). The semiquantitative score was significant improved at 4 weeks (9.03 ± 0.73 vs. 7.45 ± 0.55; p=0.033). Meanwhile, the skin thickness in the experimental group did not show decreasing trend even in the continued expansion process.
CONCLUSIONS: Autologous fat grafting represents an effective and safe method to rescue expanded skin from limited skin regeneration. This technique also represents a valuable tool to increase the chances for further expansion.
