OBJECTIVE: To evaluate the clinical efficacy of fasciocutaneous flap in the repair of the III degree burn wound in the facio-cervical region. METHODS: From January 1997 to October 2001, 11 cases of III degree burn wounds in the facio-cervical region were repaired with the cervical-thoracic fasciocutaneous flap ranging from 18 cm x 8 cm to 13 cm x 5 cm. Donor sites were covered with "Z" plasty or skin grafting. RESULTS: Except for partial necrosis of distal end of the flap in 1 case, the flaps in the other 10 cases all survived and presented satisfactory appearance and function during the following up. CONCLUSION: The fasciocutaneous flap in the cervical-thoracic region may provide a large area of flap, and can be easily transferred. It’s an ideal flap for the repair of skin defect in the facio-cervical region, especially for the repair of the wounds with infection or exposure of vessel, nerve and tendon.
Objective To review the research progress of the skin flap, fascial flap, muscle flap, and myocutaneous flap for repairing soft tissue defects around the knee so as to provide information for clinical application. Methods Domestic and abroad literature concerning the methods of soft tissue repair around the knee in recent years was reviewed extensively and analyzed. Results Fascial flaps meet the requirements of thin, pliable, and tough skin in the soft tissue repair around the knee. Myocutaneous flaps and muscle flaps have more abundant blood supply and anti-infection function. Free skin flaps are the only option when defects are extensive and local flaps are unavailable. Conclusion Suitable flaps should be chosen for soft tissue repair around the knee according to defect position, depth, and extent. Fascial flaps may be selected as the first flaps for defects repair because of excellent aesthetic results and less injury at the donor site.
OBJECTIVE In order to increase the survival area of pedicled fasciocutaneous flap, a multiple pedicled blocking randomized fasciocutaneous flap was designed. METHODS From January 1991 to September 1998, this technique was used to repair 33 cases, including 27 males and 6 females and the ages ranged from 6 to 58 years. All of the patients were suffered from traffic accidents. In these cases, 22 cases had skin defects of legs and feet with bone, nerve and tendon exposed, 5 cases had osteomyelitis as well as internal fixaters exposed and the other 6 had deformity from scar. The size of the flap was 25.0 cm x 13.0 cm x 2.4 cm at its maximum and 6.0 cm x 3.5 cm x 1.5 cm at its minimum. Based on the traditional blocking flap, according to the severity of the wound and conditions of the neighboring tissues, a flap having 2 to 4 orthogonal pedicles with a width of 1.5 to 3.0 cm was designed. The medical-graded stainless steel sheet was implanted below the deep fascia, and after blocking for 3 to 6 days, the side pedicles were divided. 6 to 14 days later, one of the two remaining pedicles was divided and was transferred to repair the defect. RESULTS 31 cases were followed up for 6 months to 5 years without any trouble of the joints. The flap had a good external appearance and was high pressure-resistant. CONCLUSION The multiple pedicled blocking randomized fasciocutaneous flap increased the size of the flap and the length to width ratio. It had the following advantages: manage at will, high resistance to infection and a large survival area of flap.
Objective To evaluate clinical significance of reversed sural neurovascular fasciocutaneous flap for reconstruction of softtissue defects in ankle and foot. Methods From July 1994 to December 2002, 52 cases of soft-tissuedefects in the ankle and foot were reconstructed by use of reversed sural neurovascular fascio-cutaneous flap, including 47 cases of traumatic defects, 3 cases of chronic ulcer and 2 cases of tumors. The flap area ranged from 4 cm×6 cm to 10 cm×21 cm. Results The flaps survived in 48 cases; the distal part necrosed and secondary free-skin graft were further conducted in 4 cases. All soft-tissue defects were repaired and their accompanied bone and tendon exposurehealed. Forty-six cases were followed-up for 5 months to 48 months, the color and texture of the flaps were excellent and 2point discrimination was 11-17 mm(14 mm on average).The functions of ankle joints were good.Conclusion The reversedsural neurovascular fascio-cutaneous flap is convenient in design and dissection. Its use can retained and replace vascular anostomosed flaps to certain degrees.
Considering the abundant vascular anastomotic networks in the deep fascia of the posterior calf, three kinds of distally based facial flap containing deep fascial vascular network were applied clinically. They were: 1. posterolateral distally based island fascial flap which could be used to repair the skin defect of heel, dorsum of foot and lateral-distal part of leg; 2. posteromedial distally based island fascial flap which could be used to repair the skin defect of heel, medial malleolus and medial-distal part of leg and 3. posterolateral malleolar distally based fascial flap which could be used to repair the skin defect of heel and lateral malleolus. Eighteen cases with soft tissue defects around the distal calf were treated, the area of skin defect ranged from 4 cm x 3 cm to 13 cm x 6 cm. All the flaps were survived completely after operation with an average of follow-up for 15 months (ranged from 6 months to 2 years). So the advantages of these flaps were as follows: the blood supply was reliable, preparation of the flap was easy and the major arteries of the calf needed not be sacrificed; the flap had a long and rotatable pedicle so that they would basically satisfy the need to repair skin defect of lower leg, dorsum of foot, heel and malleolus and the resistance of the flap to pressure and wear was better. However, the injury to the superficial sural nerve was the shortcoming.
Objective To discuss the clinical effect of repairing soft tissue defects in cnemis,ankle and foot with calf and sural distal fasciocutaneous flaps. Methods From August 1998 to July 2004, 34 cases of soft tissue defects in cnemis, ankles and feet were repaired with calf and sural distal fasciocutaneous flaps. There were 27 males and 7 females, aging from 17 to 61 years and the disease course was 4 hours to 8 months. The locations were metainferior segment of cnemis in 18 cases, ankle and foot in 11cases, weight loading region of calcar pedis in 5 cases. There were 13 cases chronic osteomyelitis in tibia or calcaneal bone, 8 cases of raw surface was infected, 3 cases of bone exposure.The sizes of the flap ranged from 6 cm×4 cm to 15 cm×12 cm. Results Thirty-one flaps survived except 3 cases which had partial necrosis. They were followed up from 6 months to 12 months. Both the quality and the appearance of the flaps were satisfactory. The blood supply and function of cnemis, ankle and foot returned to normal. Conclusion It is a convenient, simple and reliable method to repair softtissue defects in cnemis, ankle and foot with calf and sural distal fasciocutaneous flaps,without sacrifice of major arteries and with high survival rate and beautiful outlook form of skin flaps.
OBJECTIVE: To provide an anatomical basis for the clinical applications of the medial fascinocutaneous flap of calf and to verify its clinical value. METHODS: In 20 lower limb specimens of adult human cadavers, the number, course, size, position and distribution of septocutaneous branches of the posterior tibial vessels are marked by means of red latex and black ink irrigations through femur artery and septocutaneous branches of the posterior tibial artery respectively. RESULTS: The posterior tibial artery gives off several septocutaneous branches at the upper, middle and lower one-third of the leg respectively. Each septocutaneous artery has one or sometimes two concomitant veins. Based on this result, anterograde or reverse pedicled fasciocutaneous flap can be performed for the purpose of repairing soft tissue defects of leg and foot. The flap was clinically applied to treat leg and foot soft tissue defects in 12 cases with satisfactory results. CONCLUSION: The flap is easy to dissect, the posterior tibial artery can be preserved with high successful rate. Therefore, it offers an useful alternative in the repairing and reconstruction of nonextensive soft tissue defects in the leg and foot.
OBJECTIVE To research the result of defect repairing on heel with island-shaped fascial flap of lateral foot. METHODS: Twelve cases of soft tissue defected on heel, who were resulted from trauma, chronic ulcer, chronic osteomyelitis, squamous carcinoma, and necrosis following frozen injury, were treated by transfer of island-shaped fasical flap of lateral foot. RESULTS Only 2 patients suffered marginal necrosis of flap in early stage and healed after changing dressing. The others succeeded completely. All the cases were followed up for 8 to 78 months. There was no recurrence of squamous carcinoma, no fistula or necrosis bone formed. The sensation of the flap recovered. The repaired area was similar to the heel in skin texture. CONCLUSION For the characteristics of heel skin, the transfer of island-shaped fascial flap of lateral foot has the following advantages: Similar structure of skin, reliable nerve and blood supply, simple operative techniques, and large area of donor flap.
