Six cases with deformity of cicatricial contracture alter burn and one vaginoplasty were treated by using of pedicled over-thin skin flap. All were survived. The maximal ratio of length and width of skin flap is 6 to 1 and the smallest ratio is 3 to 1. Three cases were primary healing and 4 cases were delay healing. The clinical sign of delay healing shown blister or ecchymosis on distal part of skin flap. According to clinical observation, the reason of skin flap survival and advantagse of this operation were discussed.
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 study the repair and function reconstruction of complex soft tissue defect of posterior of hand and forearm. Methods From May 2001 to November 2003, 8 cases of soft tissue defect of posterior of hand and forearm were repaired with thoracico abdominal flaps with hilum for primary stage. The tendon transplantation and allogeneic tendon function reconstruction of hand were performed for secondary stage. The range of the flap was 9 cm×15 cm to 12cm×38 cm. Allogeneic tendon amounted to 6.Results All the flaps survived. The flap countour was good. The results of allogeneic tendon transplantation were satisfactory and the function of hand was good. Conclusion Repairing complex soft tissue defect of posterior of hand and forearm and reconstructing hand function by use of thoracico abdominal flaps with hilum and transplantation of allogeneic tendon have the satisfactory clinical results.
This experiment was to study the blood supply of diffcrent types of skin flaps and the revascularization of the host region. The types of skin flaps used in this cxpcriment were the axial pattern flap and the random pattern flap on the back of rabbite. Forty New Zealand rabbits were divided into 5 groups at random. In gathering the data For assessment, besides the local changes such as color, swelling of the flaps, the area of survival of flaps after division of the pedicles, the tests used to observe the postoperative changes included the isotope (99mTc) clearance test, intravenous orescein test, tissue transparent method by perfusion of the flap vessels with Chengdu ink and histologie study. The following conclusions cule be drawn: The complete revaseularization of random pattern flap occurred at 10 days after operation and that of xaial pattern flap was 14 days, the random pattern flaps had a quicker rate of revascularization. It was suggested that the flap ischemia was a factor which enhanced revascularization.
ObjectiveTo explore the surgical outcome of Duckett urethroplasty-urethrotomy for staged hypospadias repair. MethodsFifty-three patients with hypospadias were treated by 2 stages between August 2013 and September 2014. The age ranged from 10 months to 24 years and 3 months (median, 1 year and 10 months). There were 5 cases of proximal penile type, 2 cases of penoscrotal type, 36 cases of scrotal type, and 10 cases of perineal type. Urethroplasty was performed with tubed transverse preputial island flap only in 27 cases or combined with urethral plate in the other 26 cases, thus a urethrocutaneous fistula was intentionally created; stage II fistula repair was carried out at 1 year after stage I repair. ResultsThe length of the new urethra ranged from 2 to 8 cm with an average of 3.6 cm. The patients were followed up 5-17 months with an average of 8 months after stage II repair. After stage I repair, urethral fistula was noted at other site in 3 cases, skin necrosis in 1 case, glandular stricture in 2 cases, cicatric curvature in 1 case, and position and morphology of urethral orifice not ideal in 4 cases. After stage II repair, urethral fistula was noted in 2 cases, mild urethral diverticulum in 2 cases, and stricture at temporary repair site in 1 case. HOSE score was 12-16 at 3 months after stage II repair (mean, 14.5). At 3-14 months after stage II repair, the maximum flow rate ranged from 3.9 to 22.7 mL/s with an average of 8.6 mL/s. ConclusionDuckett urethroplasty-urethrotomy can be used as staged repair for primary treatment of hypospadias because of high safety, low complication incidence, and satisfactory appearance.
