Objective:To evaluate the surgical technique and clinical effect of free KISS anterolateral thigh flap in repairing soft tissue defect of dorsal side of fingers.Methods:From January, 2014 to June, 2019, 7 patients with soft tissue defects in dorsal side of multiple fingers were treated. Step one, a KISS anterolateral thigh flap was used and a temporary syndactyly between adjacent affected fingers was created by suture of the digital palmar skin. The donor sites were sutured directly. Step two, a procedure of partial de-bulking and division of syndactyly was followed-up 1-3 months later. All cases were followed-up in observations of appearance, texture, functions and donor site of flaps.Results:All flaps survived, and all went through disorders of no blood circulation. The followed-up time were 3 to 24 (average 12.5) months. The flaps had fine appearance, texture and colour. The dorsal aspects of reconstructed fingers demonstrated an aesthetically pleasing effect after the flap de-bulking and division of syndactyly. The donor site only left a linear scar, and the thigh had no functional deficit.Conclusion:Free KISS anterolateral thigh flap in repairing defects of dorsal skin in multiple fingers could simplify the operation, shorten operative time and reduce surgical trauma.

Objective: To evaluate the surgical technique and the clinical effect of the reconstruction of forearm and hand defects, using double foliated anterolateral thigh flap with a single perforator. Methods: From January 2013 to September 2017, 9 cases (forearm, n=3; hand, n=6) of the skin and soft tissue defects were reconstructed with double foliated anterolateral thigh flaps. The patients include 7 males and 2 females, with the mean age of 35.2 years(18-65 years). Blood supply of the double foliated flap was derived from the first musculocutaneous branches of the lateral femoral circumflex artery. The length and width of flaps were adjusted, to close the donor site directly. The descending branch of the lateral circumflex femoral artery was connected to the recipient vessels with end-to-end anastomosis. All cases were followed for the evaluation of appearance, texture, function and donor site condition. Results: All flaps survived, and all cases were followed for 3 to 24 months (average 10.5 months). All flaps showed no blood circulation disorder. Except for 4 cases had slightly bloated flap, the other flaps had fine appearance and texture. The donor site left only a linear scar, and the donor thigh had no functional deficiency. Conclusions Double foliated anterolateral thigh flap for repairing the large area of the skin and soft tissue defect in hand and forearm could simplify the operation, shorten operation time and reduce operation trauma. It is an ideal method to repair the skin and soft tissue defect of forearm and hand.
