Objective To discuss the advantages and disadvantages of flaps in therepairment of soft tissue defects in upper extremity. Methods Based on the 2 609 cases of flaps in 2 512 patients from 1995 to 2004,the advantages and disadvantages of different sort of flaps, outcomes of treatment and indications of different soft of flaps were analyzed retrospectively. In the series, 2 089 pieces of the traditional flaps of different sorts were applied in 1 992 patients, 474 piecesof the axial flaps of different sorts were applied in 474 patients, different sorts of free flaps were used in 46 patients. Results Follow-ups were done for 1 month to 9 years (2.7 months in average). 2 531 flaps survived (97.01%); complete necrosis occurred in 10 flaps(0.38%); partial necrosis occurred in 68 flaps(2.61%). Of the 2 089 traditional flaps, 46 had partial necrosis(2.2%); 687 needed flap revisions(32.9%). Of the 474 axial flaps, 28 had complete or partial necrosis(5.9%); 82 needed revisions(17.3%). Of the 46 free flaps, 4 had complete or partial necrosis(8.7%) and nearly all the anterolateral flpas of thighs needed revisions.Conclusion Traditional flaps had the advantages of easy manipulation and the highest survival rate, however, also had the disadvantages of poor texture and many timesof operations. The flap with a pedicle had the advantage of good texture, consistent artery, free-range arc, however, the venous congestion was its disadvantage, which impaired the survival of the reverse flap. Free flap had the advantage ofgood texture and abandant donor site, but complicate manipulation was its shortage. Axial Flap with a pedicle is the optional choicefor repairing soft tissue defects in upper extremity.
Objective To investigate the operative technique and clinical effect of perforator-based flap for repair of glutealsacral skin defects. Methods A new perforator-based flap derived from the gluteal, parasacral and the lumbar arteries was used to repair skin defects ofglutealsacral region caused by trauma or pressure sore. The flap areas ranged from 6 cm×5 cm to 19 cm×11 cm, the diametre of perforating vessel ranged from 1.3 to 2.1 mm,the length of free perforating vessel pedicle ranged from 2.5 to 4.5 cm.Results All the flaps survived andthe wound gained primary healing. All the patients were followed up for 6 to 24months. The colour and texture of the flaps were excellent, the configuration was satifactory and there was no ulcer recurrence. Conclusion This new type of flap is characterized by delicate design, easy dissection, reliable blood supply, nosacrifice of the underlying muscle and no requirement skin graft for donor site closure. It is an optimalmethod in repairing soft tissue defects of the gluteal-sacral region.
ObjectiveTo discuss the effectiveness of using dorsal two wing-shaped advancement flap to reconstruct finger web for treatment of congenital syndactyly.MethodsBetween August 2014 and August 2017, 30 cases of congenital syndactyly were treated, including 18 males and 12 females with an average age of 2.5 years (range, 1.5-5 years). Eight cases were of bilateral hands syndactyly and 22 cases of single hand syndactyly. There were 39 webs of syndactyly (including 1 case of syndactyly of middle finger, ring finger, and little finger). Among them, 11 webs were complete and 28 webs were incomplete. At the dorsum, a flap with V-shaped tip and two wing-shaped pedicle was designed and was just sewed up with an anchor-shaped incision at the palm. Distal end of fingers were separated by serrated flap and were sutured after removal of fatty tissue. In 11 cases with tight skin connection, the defect area at lateral and distal end of fingers was repaired by small pieces of full-thickness skin graft.ResultsAll the flaps survived completely after operation, and no flap necrosis occurred. The skin grafts on the distal side of the finger survived and the wound healed by first intension. All 30 cases were followed up 6-12 months, with an average of 9 months. Postoperative flexion and extension function of fingers were good, and the web depth and width were normal. At last follow-up, according to the Swanson et al. standard, 20 fingers were graded as excellent, 8 as good, and 2 as fair, with an excellent and good rate of 93.3%.ConclusionThe effectiveness of using dorsal two wing-shaped advancement flap to reconstruction finger web for treatment of congenital syndactyly is satisfactory.
Objective To introduce the new progress of perforator flaps as an new reconstruction technique. Methods The literature both at home and abroad was reviewed, and the research findings of different perforator flaps were summarized. Results The advantage of perforator flaps versus musculocutaneous flaps was the reduced morbidity of the donor site with preservation of the nerves, muscles and deep fascia. The postoperative complications at donor sites reduced. Conclusion Perforator flap was the new and reliable technique forreconstructionof tissue defect and may be one of the primary choices in the future.
