OBJECTIVE The correction of ectropion of lower lid and severe infra-orbital soft tissue depression is very difficult. Former methods included simple skin graft, tubed graft, transfer of local skin flap and so on. These methods had some disadvantages, such as not enough tissue to fill the depression, too much damage done to the donor area and operation in stages required. METHODS After investigation on the anatomy of temporal region, designed the following method. Combined transfer of the galea aponeurotica and temporal fascia was used to repair severe infra-orbital soft tissue depression and ectropion of lower lid in 6 cases. RESULTS It was discovered that the combined transfer of the galea aponeurotica and temporal fascia was rich in blood circulation because they received blood supply from parietal branch of superficial temporal artery and could be transferred to a distance as far as 15-18 cm. The skin graft used to cover the fascia usually resulted in good survival. This technique was used in 6 cases with good success. CONCLUSION This method had some merits such as the tissue flap had good blood supply, little damage done to the donor area, good correction of the severe depression, good appearance following correction, operation done under local anesthesia and completed in one-stage operation.
ObjectiveTo explore the effectiveness of anterograde fascial flap of digital artery in reconstruction of Wassel Ⅳ-D thumb duplication.MethodsTwelve 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 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.ResultsAll 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 improved in all cases. The ratio of 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.ConclusionThe 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.
目的 評價股外側肌遠端筋膜瓣折疊修復重建陳舊性髕韌帶斷裂的安全性及臨床療效。 方法 對2008年6月－2010年10月收治的10 例陳舊性髕韌帶斷裂患者，采用股外側肌遠端筋膜瓣折疊聯合減張鋼絲張力帶固定方法重建髕韌帶。術后1、2、3、6及12個月隨訪，采用美國膝關節協會評分對膝關節功能進行評分，包括膝關節疼痛、行走能力和上下樓梯能力、活動度等，同時行超聲檢查對膝關節髕韌帶的連續性進行評估。 結果 10例患者中9 例獲得隨訪，平均隨訪12個月（6～15個月）。末次隨訪時平均膝關節疼痛評分、功能評分、膝關節活動范圍均較術前明顯改善。超聲檢查顯示所有患者肌腱完全愈合，連續性完好，不需要進一步外科手術干預。所有隨訪患者均未發生手術相關并發癥。 結論 采用股外側肌遠端筋膜瓣折疊重建陳舊性髕韌帶斷裂是一種有效、可靠的方法，能夠恢復良好的膝關節功能。
Objective To investigate the effect of free anterolateral thigh adipofascial flap in correcting the hemifacial atrophy. Methods From January 1997 to May 2006, 35 patients suffering from hemifacial atrophy were corrected with microvascular anastomotic free anterolateral thigh adipofascial flap and other additional measures according to the symptoms of the deformities. There were 11 males and 24 females, aging 1547 years. The locations were left in 12cases and right in 23 cases. The course of disease was 4 to 28 years. Their hemifacial deformities were fairly severity. Their cheeks were depressed obviously. The X-ray films and threedimensinal CT showed the 28 patients’ skeletons were dysplasia. The size of adipofascial flap ranged from 8 cm×7 cm to 20 cm×11 cm. Donor sites weresutured directly. Results Recipient site wound of all patients healed by first intention. All adipofascial flaps survived. The donor sites healed well and no adiponecrosis occurred. Thirty-five cases were followed up for 6 months to 8 years. The faces of all patients were symmetry, and the satisfactory results were obtained. There were no donor site dysfunction. Conclusion The anterolateral thigh adipofascial flapprovides adequate tissue, easytosurvive, no important artery sacrificed and the donor scar ismore easily hidden. Combining with other auxiliary methods, it can be successfully used to correct the deformity of hemifacial atrophy.
Objective To investigate the effect of repairing bone defect with tissue engineered bone seeded with the autologous red bone marrow (ARBM) and wrapped by the pedicled fascial flap and provide experimental foundation for cl inicalappl ication. Methods Thirty-two New Zealand white rabbits (male and/or female) aged 4-5 months old and weighing2.0-2.5 kg were used to make the experimental model of bilateral 2 cm defect of the long bone and the periosteum in the radius. The tissue engineered bone was prepared by seeding the ARBM obtained from the rabbits on the osteoinductive absorbing material containing BMP. The left side of the experimental model underwent the implantation of autologous tissue engineered bone serving as the control group (group A). While the right side was designed as the experimental group (group B), one 5 cm × 3 cm fascial flap pedicled on the nameless blood vessel along with its capillary network adjacent to the bone defect was prepared using microsurgical technology, and the autologous tissue engineered bone wrapped by the fascial flap was used to fill the bone defect. At 4, 8, 12, and 16 weeks after operation, X-ray exam, absorbance (A) value test, gross morphology and histology observation, morphology quantitative analysis of bone in the reparative area, vascular image analysis on the boundary area were conducted. Results X-ray films, gross morphology observation, and histology observation: group B was superior to group A in terms of the growth of blood vessel into the implant, the quantity and the speed of the bone trabecula and the cartilage tissue formation, the development of mature bone structure, the remolding of shaft structure, the reopen of marrow cavity, and the absorbance and degradation of the implant. A value: there was significant difference between two groups 8, 12, and 16 weeks after operation (P lt; 0.05), and there were significant differences among those three time points in groups A and B (P lt; 0.05). For the ratio of neonatal trabecula area to the total reparative area, there were significant differences between two groups 4, 8, 12, and 16 weeks after operation (P lt; 0.05), and there were significant differences among those four time points in group B (P lt; 0.05).For the vascular regenerative area in per unit area of the junctional zone, group B was superior to group A 4, 8, 12, and 16 weeks after operation (P lt; 0.05). Conclusion Tissue engineered bone, seeded with the ARBM and wrapped by the pedicled fascial flap, has a sound reparative effect on bone defect due to its dual role of constructing vascularization and inducing membrane guided tissue regeneration.
