The comparative study of local application of magnetic piece dressings of different intensities (Gs) on the effect of survival of 48 skin flaps (2×5cm in size) and the healing of the incisional wornds was reported. Twelve Japanese long ear white rabbits were used for this study. It was noted that the magnetic field intensity of 200or 400 Gs showed remarkable increase of the area of survival of the skin flaps and enhancement of the healing of the incisional wounds.
The applied anatomy and clinical application were described in this paper. The blood supply of this flap was based on the second dorsal metacarpal artery. It gave some advantages of as easy of application, safe and reliable. Since November 1990, we had successfully used six such flaps in covering the soft tissue defects of the hand.
From 1988 through 1990, the free arteriolized venous network skin flap from dorsum of foot for skin defect of dorsum of hand was done in 8 cases. The size of the skin flap measured 10×9cm in max. and 7×6cm in min. The operation achieved good success and the clinical results were satisfactory. The mechanism of survival of the skin flap, the indications of this procedure in the repair of skin defects of the dorsum of the hand and its advantages were discussed.
A study was carried out to observe the application of microsurgical technique in the repair defects of soft tissue and infected wounds of extremities. Eighty-three patients with soft tissue defects and infected wounds of extremities were treated by either transferring of vascularized cutaneous flap or transplantation of myocutaneous flap with vascular anastomosis. The result showed that eighty-three patients had gained success after a follow-up of 6 months to 4 years. It was concluded that soft tissue defects and infected wounds of extremities should be repaired as early as possible. Selecting the donor flap near the recipient site was of first choice. The method used for repair should be simple and easily applicable rather these very complicated one. The success depended on the correct treatment of local conditions, resonable design of donor flap and close monitoring after operation.
Superficial cervical artery skin flap is widely used in clinical practice. In order to inprove the outcome of the flap in clinic, eleven cases of skin defect of scalp who were treated with the flap was discussed. After operation, the donor area healed but there was no hair growth on recipient area. Among them, six cases occurred partial necrosis of skin flaps. In order to avoid these problen, the relevant solution discussed as follows: 1. Handle well the pedicle of the skin flap to prevent the interference with venous returm. 2. Adhere strictly to indications. 3. Apply skin expander to obtain "extra" skin, then carryout the tranfer of skin flap and 4. Better use the skin flap with residual hair.
Four cases of defects of soft palate followingcomplete resection of soft palate because ofmalignant tumors had been successfullyreconstructed in which 3 patients wereperformed reconstructed with forehead flap andone patient with free forearm flap . All the flapewere survived. The appearance of the soft palateand function of swallowing were recoveredsatisfactorily from reconstruction. The operativetechnique of the reeonstruction of soft palate wasintroduced,and the points of attention ...
OBJECTIVE: To explore a new surgical management of multiple fingers degloving injury. METHODS: In 1994 to 1997, 47 cases with multiple fingers degloving injury were sutured by two reverse "s"-type skin flaps on abdominal flank. RESULTS: The skin flaps in 46 cases survived and the wounds obtained primary heal. CONCLUSION: The application of abdominal flank "s"-type skin flap is reliable and convenient in the treatment of multiple fingers degloving injury.
OBJECTIVE: To report repair and reconstruction of massively damaged wound under unusual condition. METHODS: One hundred and forty-seven patients with deep tissue defects were admitted from January 1993 to December 2000, among them, 96 cases suffered from electrical injury, 18 cases with hot press injury, 18 cases with deep burns as a result of CO poisoning or epileptic seizure, 6 cases caused by chemical producing necrosis and wound infection, 3 cases with radiation injuries, 2 cases with chemical burn, 2 cases with explosive injury, 2 cases with frostbite. One hundred and seventy five wounds in 147 patients were repaired by transfer of local flap, forearm conversal island skin flap, pectoralis major myocutaneous flap, delto-pectoral skin flap, latissimus dorsi skin flap, gastroecnemius myocutaneous flap, anterior and posterior tibial artery island skin flap, and so on. The wound defect ranged from 1 cm x 1 cm to 20 cm x 28 cm, and the flaps were 1.5 cm x 2.0 cm to 22 cm x 30 cm. The necrotic tendon was replaced with acellular allogenic tendon simultaneously in 7 cases. RESULTS: One hundred and sixty-nine flaps were survival with first intention, while necrosis of the tip of flap occurred in 6 cases. The transplantation of acellular allogenic tendon in all cases were survival. The function and configuration in 28 cases were satisfactory after 4 months to 8 years follow-up. CONCLUSION: Various types of flaps are choosen according to the position, defect range and degree of wound, which is an ideal method to restore the function and to improve patients’ living condition.
OBJECTIVE: To evaluate the application of skin and soft tissue expansion in the treatment of deformity due to extensive severe burn injury and repair of severe deep electrical burned scalp and skull with fresh wound. METHODS: From 1988, 83 cases of application of skin and soft tissue expansion were reported. In those patients with deformity due to severe burn of large area and with whole nasal defect, soft tissue expander was used under the forehead skin graft and venter frontalis, followed by reconstruction of nose with the expanded vascularized skin flap and carved cartilago costalis as nasal frame. In patients of severe deep electrical burned scalp and skull with fresh wound, skin and soft tissue expansion were used to repair the wound simultaneously with scalp burn alopecia, anesthetics and antibiotics injected into the extracapsular space of the expander in case of pain and infection. RESULTS: All of the cases were successfully treated with little pain and minimized infection. CONCLUSION: Skin and soft tissue expansion in a safe and reliable measure in the treatment of deformity due to extensive severe burn injury and repair of severe deep electrical burned scalp and skull with fresh wound.
The soft-tissue-cutaneous flap adjacent to the abdominal incisional hernia was ultilized to repair huge hernia in 6 cases with success. Patients were followed up for 2y7 years without recurrence. The operative planning, the technique and the matters needing attention were introduced in details. The soft tissues and skin adjacent to hernia used for repair was easy to obtain and a simple technique. The adoption of this operation in hospitals at the grassroots level was feasible.
