This paper reported the use of superficial temporal vessels pedicled postauricular island flap for the reconstruction of eye socket. Six cases were treated by this method since 1988 with universal satisfactory results. The disign of the flap was diseribed. The operative procedure was detailed, and the advantages of the flap were evaluated: 1. The donor defect was hidden behind the ear; 2. The flap has a relatively long pedicle, hence easy for distant transfer, and 3. the blood supply was highly reliable.
OBJECTIVE: To study the reconstructional method and effect of shoulder joint function in the older obstetrical palsy with medial rotation contracture deformity. METHODS: From April 1996 to July 1999, 7 patients of older obstetrical palsy were adopted in this study. Among them, there were 5 males and 2 females, aged from 13 to 21 years old. No previous operation history and the main deformity was medial rotation contracture of shoulder. During operation, these patients were treated with "Z"-shape elongation of the tendon of subscapular muscle, transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles. RESULTS: Followed up for 6 to 44 months(averaged 19 months), the Gilbert grading and Mallet scoring were 1.57, 7.57 preoperatively versus 3.45, 10.86 postoperatively, the abduction and external rotation of the shoulder joints recovered obviously. CONCLUSION: It is an effective operation for the older obstetrical palsy with medial rotation contracture of shoulder.
OBJECTIVE: To study the reparative and reconstructive methods for the large bone defect due to the excision of bone tumor. METHODS: According to the size and shape of the bone defect, we selected the proper bone and joint or manipulated bone segment of the profound hypothermia freezing allograft and gave locked intramedullary nails or steel plate and screws for stable internal fixation. RESULTS: In the 22 cases, 20 survived without tumor and 2 died. One patient treated with the allograft of semi-knee joint was found rejection. Then the wound did not heal. After the skin flap grafting was performed, the wound still did not heal, so the patient accepted amputation(4.5%). In the other 21 cases, the X-ray and 99mTc SPECT showed some callus or concentration of nuclein which implied bone union. According to Markin bone graft criterion, the excellent rate of function recovery was 81.8%. CONCLUSION: Allografting of bone and joint is a good and workable method in repairing and reconstructing the bone defect due to the excision of bone tumor. It should be further studied and be applied.
Objective To evaluate repair and reconstructionof the femoral pseudoaneurysm caused by drug injection. Methods From May 2000 to May 2005, 15 cases of femoral pseudoaneurysm caused by drug injection underwent operation treatment. All patients were male, aging 20-36 years. The disease course was 18-52 days(mean 35 days) and the course of druginjection was 3-17 months. The locations were the left side in 5 cases and theright side in 10 cases. After having been bandaged with pressure and supportedwith nutrition, they had been all operated. One case received fistula repair, and 14 cases received vascular grafting with ePTFE man-made blood vessel. Results The wounds healed by the first intention in 14 cases. All limbs survived. The complexion, temperature and response of involved leg were in gear. The postoperative color ultrasound Doppler detection showed that all the vascular grafts were of patency. The function of the involved limbs restored to normal. Conclusion Complete debridement, vascular reconstruction and better microsurgery skill were the key factors of treating successfullythe femoral pseudoaneurysm caused by drug injection.
ObjectiveTo review the advances in methods for reconstructing nipple projection based on tissue graft support. MethodsThe literature related to nipple projection reconstruction based on tissue graft support was reviewed and summarized in terms of the advantages and disadvantages of various tissue grafts and the improved nipple projection results. Results Loss of nipple projection is a common cause of decreased patient’s satisfaction. Reconstructing nipple projection based on tissue graft support is a more common clinical method and can be done with autologous and allogeneic tissues. Autologous tissue grafts include dermis, adipose tissue with dermis, adipose tissue, ear cartilage, rib cartilage, and contralateral nipple tissue. Autologous tissue grafts are easy to obtain and have no immune rejection, but may lead to donor area damage and prolong the surgical time for tissue collection. Allogeneic tissue grafts include acellular dermal matrix, lyophilized rib cartilage, and extracellular matrix collagen, and decellularized nipple tissue. Allogeneic tissue grafts do not cause additional donor area damage, are highly malleable, and can be designed to be utilized according to the recipient area, but the high cost often limits the development of this technique. Conclusion There is no gold standard regarding tissue graft-assisted nipple projection reconstruction techniques, and there are advantages and disadvantages to both autologous and allogeneic tissue grafts. Surgeons should choose the appropriate graft based on the actual condition of the patient.
Objective To explore the clinical effect of different types of free tissue transplantation on repairing tissue defects and reconstructing functions. Methods From November 2001 to September 2004, 14 types of freetissue transplantation and 78 free tissue flaps were applied to repairing tissue defects and reconstructing functions in extremities and maxillofacial region in 69 cases. Of the 69 cases, there were 53 males and 16 females (their ages ranged from 18 to 56, 31 on average). Five cases were repaired because of skin defects in foot, 22 cases were repaired because of skin defects in leg, 36 cases were repaired as the result of skin defects in hand or forearm and finger reconstruction, 3 cases were restored by virtue of ulna or radius defects, and 3 cases were repaired in maxillofacial region. There were 55 cases of open wound, in which 16 cases were infectious wound, 6 cases were osteomyelitis or pyogenic arthritis. There were 14 cases of noninfectious wound. The area of these tissue flaps ranged from 2.0 cm×1.5 cm to 43.0 cm×12.0 cm. The length of bone transplantation ranged from 10 cm to 15 cm. Results Arterial crisis occurred in 2 cases, venous crisis occurred in 2 cases.Seventysix flaps survived completely and 2 flaps survived partially which werelater healed. Fiftytwo cases were healed at stageⅠ, 13 cases were healed at stageⅡ(healing time ranged from 20 to 30 days), purulent infection occurred to 4cases(healing time ranged from 3 to 11 months). Bone healing time ranged from 6 to 8 weeks in finger reconstruction. Bone healing time ranged from 4 to 6 months in fibula transplantation. The function reconstruction and appearance were satisfying. The functions of all regions, where free tissues were supplied, were not disturbed. Conclusion Tissue transplantation and composite tissue transplantation are effective in repairing tissue defects and reconstructing functions.
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 study the reparative and reconstructive for proximal humerus defect due to the excision of bone tumor with noninternal fixation non-vascularised fibular autografts. Methods From June 1991 toDecember 2003, 26 non-vascularised fibular grafts were used as substitutes for repair and reconstruction after resection for bone tumors on proximal humerus. Fifteen cases were given curettage and fibular supporting internal fixation, the other 11 cases were given tumor resection and joint reconstruction with proximal fibular graft. The age ranged from 6 to 41 years. Out of 26 patients, 5 had giant cell tumor, 9 had bone cysts, 8 had fibrous dysplasia and 4 had enchondroma. Results Twenty-six patients were followed up from 1 to 12 years (3.4 years on average). Local recurrence was found in 2 cases, and 1 of them died of lung metastasis. Both outlook and function of the reconstructed joints have good results in 15 proximal humeral joint surface reserved cases. Of them, 3 children gained normal shoulder function 3 weeks after operation. Part function were obtained in the other 11 fibular grafts substituted proximal humeral defect. Conclusion Non-vascularised fibular grafts is an appropriate treatment option for proximal humerus bone defect due to excision of bone tumor.
Objective-To apply self-pulmonary tissue flap to reconstruct esophagus directly or with alloy stent in this research. Methods Twenty-four dogs were divided into two groups, middle bronchus was ligated to prepare pulmonaryflap and incised, a 4 to 6 cm long and 1/2 to 2/3 perimeter defect was made in esophageal wall. Esophagus defect was repaired only with pulmonary flap (experimental group) and with pulmonary flap having self-expanded stent inside (control group). The gross appearance, histological apearance and barium X-ray films were observed at 2,4,6,8,10 and 12 weeks after operation. Results Two dogs died of anatomotic leak in experimental group, three dogs died of anatomotic leak and two dogs died of perforation of ulcer in control group. The growth of esophagus epithelium was observed from periphery area to central area after 8 to 10 weeks of operation. In pulmonary flap mass fibrous tissue proliferated and fibroblasts were active, but no necrosis occurred. Barium X-ray ofregenerated esophagus showed that mild stenosis and weakened peristalisis were observed in the middle of resophagus replacement, and that no obstruction, leakage, and dilation above anastomotic stoma occurred. Conclusion Pulmonary tissue flap can well support the mucosa crawl in the defect of esophagus. It is necessary to find a more suitable and satisfied stent for repairing segmental defect.
One hundred and twenty-eight cases of peripheral aneurysm were reported.Traumatic prsucdoaneursyms(87cases)dominated and aneurysm in lower extremities(68 cases)consisted of most the cases.Rupture of aneurysm and massive kaemomhage is the most serious complications(22 cases in the report).Therefore,operative treatment should be performed soon after the diagnosis is ascertained.Resteration of normal blood flow should be the aim.Intracystic repairation is indicated in pseudoaneurysm with part of the vascular wall invaded.Artificial graft may be indicated for aneurysm of the middle and large artery,and autovenous graft for the smaler arteries.Aneurysm may be resected if the procedure is easy to perform or there is severe inflammation around the aneurysm.Proper postoperative drainage is important.General heparinization during blockade of local circulation is also important in case of vascular grafting. We concluded that proper selection of operative procedure is essential for better prognosis.
