ABSTRACT
Objective To analyze the difference of soft and hard tissues between beautiful face and ordinary face in young Han women for providing data basis for modification of lower facial contour.Methods 38 cases of young Han women were selected with craniofacial spiral CT scanning,three-dimensional reconstruction and histomorphometry of the mandibular angle region (12 cases of beautiful face and 26 cases of ordinary face).Results The difference of bony bigonial breadth,lower face width,angle of mandibular angle,mandibular branch width and height,the distance between the mandibular angle point and pogonion in mandibular angle region had statistical significance (P ＜ 0.05);the difference of mandibular angle thickness had no statistical significance (P＞0.05);the difference of masseter muscle length,width and thickness had statistical significance (P ＜ 0.05).Conclusions In clinical lower facial contour modification practice,we can refer to the data of soft and hard tissue of mandibular angle region of beautiful face,combining with the specific circumstances of the pursuit of beautiful people and select the appropriate surgical approach for lower facial contour modification.
ABSTRACT
Objective To determine whether rTFPI could inhibit vascular thrombosis and salvage random pattern skin flaps following AIRC in rat models.Methods From April,2013 to June,2015,30 adult male Sprague-Dawley rats were randomized into 3 groups;a control group,an avulsion injury with roll compaction (AIRC) group,and an AIRC plus rTFPI therapy group.An 8.0 cm× 2.5 cm random flap was raised on the dorsum of each rat.The AIRC and AIRC plus rTFPI flaps were then altered with a device designed to simulate avulsion injury with roll compaction.After flap closure primarily,treatment was initiated immediately and continued for 3 days.Phosphate buffered saline was used in the control group and the AIRC group,while the AIRC plus rTFPI group received the recombinant Tissue Factor Pathway Inhibitor.Laser Doppler flowmetry and infra-red thermalgraphy were used on postoperative day three to assess nicrocirculatory blood flow and viability of the avulsed flaps.At postoperative day seven,final flap survival was determined.Using SPSS19.0 statistical analysis.Results The flap survival in AIRC group was only (32.7 ± 5.2)％ versus (62.5 ± 6.5)％ in control group,but the flap survival significantly increased (51.6 ± 8.2)％ after topical injecting rTFPI in experimental group.Statistically significant differences exist (P ＜ 0.05) between every two groups.The detection results of Laser-Doppler flowmetry and infra-red thermography showed that perfusion arrived the centre of the flaps in experimental group,while perfusion only arrived the proximal part of the flaps in the AIRC control group.Conclusion rTFPI therapy is effective in reducing ischemic necrosis of random pattern flaps following avulsion injury in the rat model.It suggests that rTFPI therapy may play an important role in clinical salvage of the failing avulsion injuries with roll compaction.
ABSTRACT
Objective To explore the clinical effect of transplantation of autologous fat with stromal vascular fraction for breast augmentation.Methods From September 2012 to March 2014,15 people accepted breast augmentation by transplanting autologous fat with SVF under local anaesthesia.Three-dimensional computer tomography reconstruction (3D-CT reconstruction) was applied preoperatively and postoperatively,the data of the thickness of breast's subcutaneous tissue was compared to observe the breast contour improvement.Results Autologous fat was injected 2 times in 3 cases,and the rest were 1 time.6 months after operation,13 cases were satisfied with the results,and 2 cases were quite satisfied.3D-CT reconstruction was performed before operation and 6 months after operation;statistics showed that before operation the thickness of breast subcutaneous tissue of the right side was (11±4) mm,the left side was (11±6) mm;6 months after operation the right side was (14±3) mm,the left side was (16±3) mm (P＞0.05).The breast was soft,no major complication such as nodules,cysts or calcification were seen.Conclusions The transplantation of SVF with autologous fat is a safe,effective procedure for breast augmentation.3D-CT reconstruction can show more details of breast structures,which is a more effective method to guide and evaluate the lipotrans plantation.
ABSTRACT
Objective To observe the surgical results of milling technique in treating mandibular angle hypertrophy through an intraoral approach and the effect of three-dimensional computer tomography (3D-CT) reconstruction.Methods Milling-technique was used to treat mandibular angle hypertrophy of 43 patients through intraoral approach under local anaesthesia.3D-CT was applied preoperatively and postoperatively,the data of mandibular angle and masseter muscle thickness were compared preoperatively and postoperatively.The facial contour improvement was also observed.Results Of 43 cases,33 cases were followed-up for 4 to 24 months after operation.The majority of patients were satisfied with the aesthetic results,changes of anterior and lateral view of basifacial part were obvious,the curve of the mandibular angle was smooth and the shape was natural; no major complications such as facial nerve injury or malfracture were seen.Conclusions Milling-technique is a safe,effective and simple method for mandibular angle reduction,and 3D-CT reconstruction has a positive effect preoperatively and postoperatively.
ABSTRACT
Objective To explore an ideal surgical treatment for cervical sear eontraeture. Methods From January, 2005 to December, 2008, 11 eases of cervical sear contraeture (Ⅱ-Ⅲ) were treated with the expanded flaps based on the cervical cutaneous branch of transverse cervical artery. At the first step, one or two soft tissue expanders were implanted beneath the skin at the clavicular-pectoral region. At the second step, after fully expanding, an expanded clavicular-pectoral flap that based on the cervical cutaneous branch of transverse cervical artery was designed and raised completely according to cervical cutaneous defect. And then, the flap was transferred to reconstruct the defect in cervix. The donor area was closed directly or covered with graft. Results The 11 cases were performed with unilateral flaps based on the cervical cutaneous branch of transverse cervical artery. No necrosis occurred. And the cervical contour and function have been mended. All of them had been followed up for 6-18 months with satisfactory results. Conclusions This procedure can be very useful for the plastic and reconstruction surgeons who are confronted with a difficult case of cervical scar contracture. By this means, a lot of materials of reparation with similar color, and texture can be obtained. And this method is simple, safe, and effective.
ABSTRACT
Objective To explore the effects of Medpor in surgical treatment of craniofacial de-pressed deformities. Methods Combining with other surgical methods, 37 patients with craniofacial de-pressed deformities were treated with Medpor. Of them, 29 cases of craniofacial depression and defects subjected to trauma, 6 cases were progressive facial hemiatrophy and 2 case were angle of mandible de-formity. All were followed up from three months to four year. Results Facial configurations and func-tions of all the 37 cases were greatly improved after the treatment, without any complication of infection or rejection;patients were all very satisfactory or relatively satisfied with the results. Conclusion Med-por is an ideal implant material to correct the deformity of earaniofacial, and combining with others methods, the treatment of earaniofacial deformity can obtain good results.
ABSTRACT
Objective To explore an effective treatment for lactation complications after augmenta-tion mammoplasty with polyacrylamide hydrogel (PAHG). Methods 13 cases with lactation complica-tions after augmentation mammoplasty with polyacrylamide hydrogel (PAHG) were treated with taking out PAHG and the pathological tissue through the periareolar incision, using continual drainage and medi-cation that can choke back hypergalactia. Results All cases were cured and followed up for 3 months to 4 years with satisfactory results. Conclusion This method for the treatment of lactation complications after augmentation mammoplasty with PAHG is effective, safe and simple.
