Introduction This article aims to expand the microsurgical treatment options for extremity degloving injuries with perforator artery repairs of the specific degloved angiosomes in upper and lower extremity. Methods Fourteen perforator arteries were repaired in seven patients. Four of them had circumferential degloving and 3 of them have non circumferential degloving injury. All had repair of the perforator arteries of the specific degloved segments. Four patients had additional vein repairs but none of the patients had AV shunts. Results All perforators provided adequate arterial supply to their specific angiosomes with some necrotic areas in neighboring angiosomes. Conclusions Perforator artery repair within the degloved tissues provides a direct arterial supply successfully even if one could not find an intact venous plexus.

In addition to soft tissue and bone tissue injuries as a result of high-energy trauma against the lower extremities, serious tissue losses may occur following tumor surgeries. For the reconstruction of this region, there are various options. The preferred methods of reconstruction vary with respect to the experience and knowledge of the surgeon. In this case, the mega prosthesis used following a tibia tumor resection by virtue of local flaps is discussed. [Hand Microsurg 2016; 5(2.000): 92-95]

Demir, Ahmet/0000-0002-8820-3122; WOS: 000367303700001 PubMed: 26710014 Background: Early degradation is a common complaint for hyaluronic acid fillers. Although the combination of hyaluronic acid fillers with botulinum neurotoxin type A presented improved clinical results, objective measurement of hyaluronic acid volumes has not been previously assessed. Methods: In this study, the authors have split the calvaria of the rabbit to mimic the glabellar region in humans. In this model, the authors applied hyaluronic acid alone to one side and hyaluronic acid combined with botulinum neurotoxin type A to the contralateral side. Two days and 3 months after the filler injection, magnetic resonance imaging was performed to assess the filler volumes. Results: Average initial volume of filler only and filler combined with botulinum neurotoxin type A was 0.61 cm(3) on both sides, and there was no difference between initial volumes of the two sides (p = 0.735). At the end of 3 months, average degraded volumes of filler-only and filler combined with botulinum neurotoxin sides were 0.33 cm(3) and 0.19 cm(3), respectively, and the degradation difference was significant between the two groups (p = 0.001). End volumes for the filler-only and filler combined with botulinum neurotoxin sides were 0.28 cm(3) and 0.42 cm(3), respectively, and end volumes between two sides were also statistically significant (p < 0.001). Conclusion: This study showed that hyaluronic acid filler application in combination with botulinum neurotoxin type A significantly decreases the degradation process and increases the remaining volume of the hyaluronic acid fillers at the end of the paralyzed period.
