ABSTRACT
Objective: To explore the effectiveness of anterograde fascial flap of digital artery in reconstruction of Wassel Ⅳ-D thumb duplication. Methods: Twelve cases of Wassel Ⅳ-D thumb duplication were treated with anterograde fascial flap of digital artery between June 2014 and March 2017. There were 7 boys and 5 girls with an age of 9-32 months (mean, 13.3 months). Eight cases were on the left side and 4 cases on the right side. The main bunion bed width was 70%-85% of the healthy side (mean, 75.3%). The degree of fullness was 50%-75% of the healthy side (mean, 62.4%). The anterograde fascial flap with one proper digital artery was used to fill the nail fold on the radial side of the finger and increase the circumference of the finger. At last follow-up, the ratio of abdominal circumference of deformed finger to contralateral finger was measured at the base of nail. The appearance and function of all reconstructed thumbs were evaluated with Japanese Society for Surgery of the Hand (JSSH) scoring. Results: All the operations were successfully completed without early complications such as infection and skin necrosis. All children were followed up 7-27 months (mean, 14.3 months). At last follow-up, there was no recurrence of deformity in the digital body and no obvious change of scar contracture in the surgical wound. Pulp and nail fold symmetry was improved in all cases. The ratio of abdominal circumference of deformed finger to contralateral finger was 93%-96% (mean, 94.7%). The JSSH score was 15-20 (mean, 17.9); the results were excellent in 8 cases, good in 2 cases, and fair in 2 cases. Conclusion: The anterograde fascial flap of digital artery is a safe and effective approach to restore symmetry for esthetic improvement in treatment of Wassel Ⅳ-D thumb duplication.

ABSTRACT
Objective The tissue engineering technique and the microsurgery technology is combined to construct the uncellular tissue engineering complex with vascularization and membrane guided dual effect. Through comparing study of using the simple biomembrane guided bone regeneration technique to construct the uncellular tissue engineering complex to repair the large segment bone defect in the animal body,the bone reparative effect of the tissue engineering bone wrapped by pedical fascial flap with vessels and that wrapped by the simple biomembrane was compared, thus to provide experimental evidence for the clinical application. Methods Twenty-four Newzland 5-month-old rabbits were used to build the bilateral periosteumincluded bone defect modelsin the middle piece of the ulna and the length of the defect was 1 cm. Autologous red bone marrow was implanted in the tissue engineering bone which was prepared by osteoinductive absorbing material including BMP. The prepared tissue engineering bone was implanted in the bone defect area. The right side was wrapped by the simple absorbable biomembrane, whereas the left side was wrapped by pedical fascial flap with blood supply. At the fourth, eighth, twelfth and sixteenth week after the operation each group was examined by the radiograph (x-ray), the light density measurement, gross morphology and histological inspection,bone shape measurement analysis in the repairing area and the biomechanics measurement at the twelfth week. The data was analyzed to test the difference of the bond defect repair. Results The radiograph, gross morphology and histological inspection showed the growth of vessels in the implant area, the quantity and the forming speed of the bone trabecula and, the cartilaginous tissue, the formation of the mature bone structure,remodeling of the diaphysis, recanalization of the cavum ossis and the absorption and the degradation of the implant of the group of pedical fascial flap with blood supply was superior to that of the group of the simple absorbable biomembrane. At the fourth, eighth, twelfth and sixteenth week after the operation the bone trabecula area were( 20. 35 ± 2. 41 ) %, ( 40. 21 ± 1.97 ) %, (66. 67 ± 3.44 ) % and ( 86. 47 ± 3.99) % respectively in the group of pedical fascial flap with blood supply, and were ( 7. 46 ± 2.64 ) %, ( 20. 66 ± 2. 28 ) % , ( 40. 22 ±1.84)% and(58. 18 ± 1.79) respectively in the group of the simple absorbable biomembrane. At the same time point after the operation the light density were 0. 636 ± 0. 012,0. 596 ± 0. 062,0. 552 ± 0. 009 and 0. 451 ±0. 008 respectively in the group of pedical fascial flap with blood supply, and 0. 742 ± 0. 032,0. 713 ± 0. 022,0. 655 ±0. 018 and 0. 606 ±0. 015 respectively in the group of the simple absorbable biomembrane. The units of blood vessel reproductive area in the bone repair junctional zone were ( 18.75 ± 2. 09 ) %, ( 37.41 ± 3.22 ) %,(53. 06 ±2. 18)% and (36.72 ±4. 73)% respectively in the group of pedical fascial flap with blood supply,and (5. 34 ± 1.17 ) %, (9. 48 ± 2.96) %, ( 22.43 ± 2. 21 ) % and ( 26. 27 ± 3. 14 ) % respectively in the group of the simple absorbable biomembrane. The biomechanics intension was 26.62 ± 3.96 in the group of pedical fascial flap with blood supply and 18. 38 ±0. 71 in the group of the simple absorbable biomembrane at the twelfth week after the operation. All of the differences were significant( P ＜0. 05 ). Conclusion The pedical fascial flap with blood supply has significant effect in promoting the tissue engineering bone to vascularize and promoting the bone formation by vascularization. The membrane guided bone regeneration technique restricted not only the growth of the fibrous connective tissue in the reparative process of the large segment bone defect effectively, but also the ability of fast and effective vascularization, thus the chronic creep and substitution process would be needed. Simple application of the biomembrane can compensate the shortcoming of chronic creep of the implanted material by the growth of the external callus.
ABSTRACT
Objective To study the effect of fascial flap with vessels inducing the vascularization of uncel-lular tissue engingeering complex and the regenration of bone on the repair of bone defect, so as to provide the basis for the clinical application. Methods An animal model of bone defect on adult Newzland rabbits'right radial bone was established .and autologous red bone marrow were taken out and mixed into uncellulax tissue engineering comple-xes with OAM which contained BMP. The experiment animals were divided into two groups : experiment group and control group( n = 12 for each ). The control group was only implanted with complexes, meanwhile, the experiment group had fascial flap with vessels. By microsurgery technology,a non-named fascial flap with vessels was prepared, which belonged to capillary net,around the bone defect,and let it wrap tissue engineering complex,fill up bone de-fect. In a certian time, radiograph(X-ray) and light density measure was conducted, gross morphology and histological inspection was exmained. Bone shape measurement analysis and image of vessel analysis were conducted. All the sta-tistics were analyzed by the SPSS 11.5 software. Results Because of mechanically preventing fiber connective tis-sues and surrounding soft tissues from entering the areas of bone defect by fascial flap, it can keep bone defect having a relative stable environment ;The subfascial space itself, and also the shape and mass of filled-in subject had the de-cisive effect on the results of the regeneration of the bone; Owing to the establishment of blood supply during the con-structing tissue engineering complex. The experiment group was obviously superior to the control group. Compared with control group,the absor bance obviously increased in experiment group [(0. 732 ± 0. 021 ) vs (0. 651± 0.018)] (P < 0. 001 ) four weeks after the operation; also the bone trabecular body was significantly increased [(2.32±2.57)% vs(19.37±3.52)% ,(8.37±3.52)% vs(30.24±3.42)% ,(28.57±2.98)% vs(58.76± 4.62)% ,(47.24±3.42)% vs(88.72±5.84)%] ,and capillary area [(5.04±1.62)% vs(17.53±2.86)%, (10.37 ±2.96)% vs(35.24±1. 13)%,(18.20±2. 12)% vs(48.76±4. 62)%,(17.82 ±2. 74)% vs (57.72 ±5.84)%] (P <0.05) at each time period(4 weeks,8 weeks,12 weeks,and 16 weeks after operation). Despite of growth of implant's internal vessel, the number and speed of forming bone trabecula and cartilaginous tis-sue, even developing of mature bone structure, recreating of diaphysis structure, reconstructing of marrow cavity, ab-sorbing and decomposing of implant, the experiment group was obviously superior to the control group. Conclusions The induction of fascial flap with vessels shows double effects, one of which is the vascularization of uncellular tis-sue engineering complex and the other is membrane guided bone regeneration, So the method has a wonderful effect on the repair of bone defect.
ABSTRACT
Objective To explore the method of treatment of sunken cheek deformity.Methods The longitudinal platysma-faseial flap was overturned 180 degree upward,the flap's pedicle located in the margin of mandible,and then combined with abdominal dermis fat graft to form as a sandwich,which filled in the sunken area of face.Results Five patients were treated with this method from 2003 to 2007,and satisfactory results were gained but only mild absorption was found in the transplanted tissue area during followed up for 3 months to 3 years.Conclusion Platysma-fascial flaps survive easily with rich blood supply and strong anti-infection,and are also easy to incise and operate as well,which,together with free abdominal dermis fat flap,could increase the amount of the needed tissue.It is a better approach to repair the sunken cheek deformity and in particular suitable for the more serious deformity in patients with sunken cheek.

ABSTRACT
Objective To introduce a new technique of one-stage auricular reconstruction by using the retroauricular fascial flap. Methods The retroauricular fascial flap was designed to cover a cartilage framework for auricular reconstruction. Results Seventeen cases who had injured over two years and received no surgical treatment, underwent auricular construction. In 3-month to 2-year follow-up, all patients obtained satisfactory appearance of the reconstructed ears that possess delicate structure and close color to adjacent skin. Conclusion For retroauricular fascial flap has adequate blood supply, it makes operating procedure simple and the occurrence rate of complication reduced. It is proven that this is a good method of auricular reconstruction.
ABSTRACT
The superficial temporal fascia is a thin, pliable, well- vascularized flap that is useful in elevation of the reconstructed ear of the microtia. However, the elevation of the superficial temporal fascial flap by conventional T or zigzag incisions in temporal region frequently leaves a conspicuous scar, hair thinning and alopecia. To overcome these problems, we harvested the superficial temporal fascia as a random pattern flap using only a retroauricular skin incision line for the ear elevation. Thereafter, the cartilage framework was elevated including superficial temporal fascia and superficial mastoid fascia underneath: dissection plane was continuous with the superficial temporal fascial flap harvest and dissection was performed just beneath the superficial mastoid fascia under the framework. A carved costal cartilage block was grafted at the posterior wall of the concha and covered with the harvested superficial temporal fascial flap, followed by a full-thickness skin graft. From June 2001 to December 2001, 9 patients (male 8 and female 1), who ranged from 9 to 26 years in age, underwent ear elevation using this method. The skin grafts was successful and the appropriate auriculocephalic angle was preserved in all cases. We did not find any complications such as infection, graft loss or cartilage extrusion in the 3 to 9 months follow-up period and the patients were satisfied with their cosmetic results. This method was easy to perform and did not leave any other scar in the temporal hear-bearing area and the results have been favorable.
