Application of KISS anterolateral thigh flap in repairing soft tissue defect of dorsal side of multiple fingers

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.
