ABSTRACT
Gradual distraction with an external fixator is a widely used treatment for severe postburn ankle contracture (SPAC). However, application of external fixators is complex, and conventional two-dimensional (2D) imaging-based surgical planning is not particularly helpful due to a lack of spatial geometry. The purpose of this study was to evaluate the surgical planning process for this procedure with patient-specific three-dimension-printed models (3DPMs). In this study, patients coming from two centers were divided into two cohorts (3DPM group vs. control group) depending on whether a 3DPM was used for preoperative surgical planning. Operation duration, improvement in metatarsal-tibial angle (MTA), range of motion (ROM), the American Orthopedic Foot and Ankle Society (AOFAS) scores, complications, and patient-reported satisfaction were compared between two groups. The 3DPM group had significantly shorter operation duration than the control group ((2.0±0.3) h vs. (3.2±0.3) h,
ABSTRACT
Objective@#This study aimed to present our clinical experience using a novel method for autologus costal cartilage framework fabricationin fully expansion technique ear reconstruction without skin graft.@*Methods@#During Steptember 2016 to Steptember 2017, autologus costal cartilage framework with expansion technique were performed for 63 patients with microtia. Autologous costal cartilage was stacked up to form the structure and height, the natural appearance of auriculocephalic angle was achieved at the same stage, so the second-stage elevation of ear and postauricular skin graft was unnecessary. The delicate structure of the reconstructed ear and ideal bilateral symmetry were achieved by the optimized cartilage stack-up.@*Results@#Three patients out of total 63 patients had cartilage frame work exposure, and were treated with superficial temporal fascia transfer combined with skin graft. The rest 60 patients had satisfied results. Follow-up ranged from 8 months to 18 months and 12 months follow-up was on average. The novel frame work fabrication method was based on the sufficient full pre-expansion procedure. The ideal structure, bilateral symmetry, and excellent definition of the framework, as well as the natural dorsal appearance of the reconstructed auricular were achieved.@*Conclusions@#The cartilage " stack-up" method is essential for the full expansion without skin grafts ear reconstruction technique. The combination of the cartilage " stack-up" framework fabrication and full pre-expansion provide a well-defined, well-projected and bilateral symmetrical ear.
ABSTRACT
Objective@#This study aimed to present our clinical experience of the utilization of remnant ear for the inferior part and lobule reconstruction in microtia patient with the fully pre-expansion ear reconstruction technique.@*Methods@#During 2017.01—2018.12, 156 cases of unilateral ear reconstruction were performed. The operation was divided into three stages. Six months after the ear reconstruction, the third stage of the remnant ear utilization was performed. The surgery was planned according to the microtia classification and the remnant morphology.@*Results@#All the patients had no complications. Follow-up period ranged from 7—24 months, and ten months on average. All the patients with typeⅠmicrotia had satisfying results of the inferior part and lobule reconstruction. Sixteen cases of types Ⅱand Ⅲ microtia patients had unfortunate outcomes, because the residual ears were too small to reconstruct the earlobe, and the incisure appeared when remnant and reconstructed ear was connected in cases of severe remnant malposition. The rest of patients were satisfied with the reconstruction.@*Conclusions@#The utilization of the remnant ear based on the types of microtia and the remnant morphology could achieve the satisfying result of reconstruction for most of the microtia patients.

ABSTRACT
Objective To explore a better method to repair cervical cicatricle contracture deformity.Methods The cervicai cicatrical contraction deformity was repaird by the cervico-shoulder island skin flap with blood supply crossing and abundant anastomotic branches of the neck-shoulder blood vessels. After removing the cervical scar, the flaps were designed according to the size of the wound to be repaired, and the clinical anatomy of crossing and abundant anastomotic branches of the neck-shoulder blood vessels. The secondary wound of donor site was closed directly if the donor region was small, or closed by skin graft. Results Sixteen patients in this clinic were operated with this method, and venous return dysfunction occurred in 1 case, but blood circulation was improved after treatment. All the flaps survived with good appearance and texture. The extensive flap was created and transferred to the anterior neck by one stage without pre-expansion which met some patients'requirement of repairing cervical cicatricle contracture deformity. Conclusion The cervico-shoulder island skin flap, with abundant blood supply, is a new method to repair cervical cicatricle contracture deformity.
ABSTRACT
Objective To explore the technique of massive facial scar revision. Methods All 12 patients in the group were treated with expanded deltopectoral skin flap. In the primary surgery, expander was implanted underneath deltopectoral flap region through an incision inferior to the clavi-cle. The skin perforators of transverse cervical artery and thoracoacromial artery were ligated during surgery, and the internal thoracic artery was carefully preserved. After the deltopectoral skin flap was fully expanded, the second surgery was performed and the facial scar was released and the normal ana-tomic position of eyes, nose and month was restored. The deltopectoral skin flap was planed according to the size of the defect. The excised facial scar was converted to the flap pedicle and a hinge-like con-nection was formed. The flap was delayed and three weeks after the second surgery, the pedicle was divided. The flap from the pedicle was applied for the mental region scar revision. Results Unilateral or bilateral dehopectoral skin flaps were employed for the repair of extensive facial scar in 12 patients. Satisfactory results were achieved in all these patients. Conclusion Expanded deltopectoral skin flap is a good technique for the repair of extensive facial scar.
ABSTRACT
Objective To explore the aesthetic effect of the applying the expanded skin flap to re-pair facial defects produced by removal of nevus, hemangioma, scars and so on. Methods The experience of the treating 67 patients with facial lesions using the expanded flaps were reviewed. The proper expand-ers were chosen according to the scope of the facial lesion. The incision was located at the scar region and the dissection was executed in the superficial layer of the SMAS. The interspace was larger than the ex-pander by 1.0～1.5 cm. After exact hemostasis, the expanders and negative pressure drainage tubes were placed into the interspace. The design of the facial expanded skin flap included the advance, rotation, and transposition of skin flap and so on. The advance of skin flap took fully use of the expanded skin flap without the donor site defect. The transposition of skin flap also took fully use of the expanded skin flap, furthermore, it overcame the displacement and the disfiguration caused by the applying of the advance skin flap and rotation skin flap. The incisions in face were designed to a minimal extent and parallel to the Lan-ger line. Results All of the 67 cases got aesthetic satisfied results with all the flaps surviving. Conclusion The application of expanded skin flaps is proved to be an effective way of repairing facial wound when there is enough normal facial skin for expansion.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the influence of the endothelial cells on the scar-derived fibroblasts in the hypertropic scar tissue.</p><p><b>METHODS</b>The endothelial cell from the human umbilical vein was cultured and its supernatant was then collected. Thereafter, it was mixed with the pre-cultured scar-derived fibroblasts from the hypertropic scar tissue. The fibroblasts were analyzed with a flow cytometer in a MTT-assay method to evaluate the cell proliferation and its division cycle.</p><p><b>RESULTS</b>The endothelial cells were significantly increasing the scar-derived fibroblast proliferation (P < 0.05), compared with the control. The proportion of the fibroblasts in the S-stage of cell cycle was also quite high.</p><p><b>CONCLUSION</b>The endothelial cells may secrete some active products, which may enhance the proliferation of the scar-derived fibroblasts and stimulate the fibroblasts into the S-stage of cell generation cycle.</p>
