Abstract:
Objective:To explore the clinical effect of a self-designed wound measurement grid on the design of lobulated perforator flap.Methods:From January 2019 to December 2022, soft tissue defects in limbs of 9 patients were reconstructed by lobulated perforator flaps in the Department of Orthopaedics and Traumatology of Shenzhen Hospital of Integrated Traditional Chinese and Western Medicine. The patients were 7 males and 2 females aged 21-55 years old with 40.3 years old in average. There were 6 upper limb defects and 3 lower limb defects. Self-designed wound measuring grids were applied to guide the design and excision of lobulated perforator flaps during surgery. Five patients were treated by lobulated perforator flap pedicled with the descending branch of lateral circumflex femoral artery and 4 by perforator flaps pedicled with dorsal interosseous artery. The areas of soft tissue defect were 4.0 cm×1.5 cm-26.0 cm×8.0 cm, and the sizes of the flaps were 4.5 cm×1.8 cm-22.0 cm×10.0 cm. After surgery, the blood supply of flaps, flap survival and wound healing were monitored. Flap survival, donor site recovery and limb function were observed at outpatient clinic over the postoperative follow-up, and the limb function was evaluated by the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association and Lower Extremity Measure(LEM).Results:In this study, a total of 17 of 18 lobes of the lobulated perforator flaps survived after surgery. One flap had venous occlusion and after exploration and further treatment, a necrosis occurred in 1 lobe of the lobulated flap and then a free flap transfer was performed again. All the wounds achieved stage-I healing. Postoperative follow-up lasted for 3-18 months with 8.6 months in average. All flaps had good colour and texture, satisfactory appearance and only linear scars remained in the donor sites, without pain and scar contracture. The reconstructed upper extremity defect were evaluated according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, with 4 patients were in excellent and 2 in good. The reconstructed lower extremity defects were evaluated according to the LEM, and 2 patients were in excellent and 1 in good.Conclusion:The self-designed wound measurement grid was successfully applied in the design of lobed perforator flaps. It can accurately measure a wound surface and quickly extract a wound profile, and it is more convenient and intuitive to guide the design of flaps. It has a good effect in clinical application and further clinical trials are required.
