Effect of diclofenac sodium on KC/MC ratios and content of PGE_2 in epidermis of the full-thickness skin autografts

Chinese Journal of Medical Aesthetics and Cosmetology.2002;0(02):-.

Objective To study effect of diclofenac sodium on content of prostaglandin E 2 KC/MC ratio and hyperpigmentation of the full-thickness skin autografts. Methods Content of PGE 2 was determined by radioimmune analysis method, and kinetic changes of KC/MC ratio were observed with histological and histochemical methods. Results In the operation control group, increase of KC/MC ratios was accompanied by of PGE 2 content at the early stage of the experiment; and the KMR became smaller than that in normal control group at the end of the experiment. While in the diclofenac soduim group, KMR was reduced due to the less damage of MC at the early stage, with decrease of PGE 2. Accordingly, KMR became larger at the late period of the experiment, and color of the autografts became lighter. Conclusion Application of diclofenac sodium on the grafts just after transplantation may reduce the damage of inflammation to the epidermal melanin units, control their proliferation and decrease the value of KMR, which lightens the color of the grafts.

Objective To verify the ability of distal ends of internal mammary artery and vein used as recipient vessels on breast and chest wall reconstruction. Methods Four bilateral (left 2 and right 2) scent pig buttock island flaps pedicled circle deep iliac artery and vein were used by comparing the different hemodynamic parameters (pressure; flux volume; perfusion unions) between the original pedicl artery (deep iliac artery), proximal and distal ends of internal mammary artery. The free flaps were transplantated by anastomosed end-end to the distal-ends of internal mammary artery and vein after the proximal ends were ligated. Results The pressure of distal end of internal mammary artery was 61%-65% of the pressure with original pedicl artery (deep iliac artery), the immediate volume of anastomasis stoma was a little lower than that of original pedicl artery. The flap, 15 cm?30 cm?2 cm in size, completely survived more than 14 days after operation. Conclusion The slightly decreased distal arterial pressure does not compromise flap survival. Bilateral scent pig buttock island flap pedicled circle deep iliac artery and vein is an ideal animal flap model. This hymodynamic model can be widely used .

Objective Developmental mandibular asymmetry is a common deformity in the human craniofacial skeleton and the treatment is not easy to get satisfactory results. A retrospective study was performed to investigate the clinical results and stability after treatment of developmental mandibular asymmetry by using combination of orthognathic surgery with orthodontics. Methods 58 cases of developmental mandibular asymmetry were treated by preoperative orthodontics-orthognathic surgery -postoperative orthodontics procedure. 82 times of operation, such as mandibular osteotomy, bimaxillary osteotomy, jaw plastic surgery, genioplasty, and distraction osteogenesis were performed according to different type of asymmetry. The facial appearance and occlusion relationship were evaluated with 1～4 years of follow-up. Results Satisfactory results were achieved in 53 cases (91.4 %). Primary satisfactory results were obtained in 4 cases (6.9 %). 1 case (1.7 %) with unsatisfactory result obtained aesthetic effect and ideal occlusion after operation again. Conclusions It is essential to use both of orthodontics and orthognathic surgery in order to ameliorate facial appearance, resume occlusal function, achieve good corrective result and prevent the recurrence of the developmental mandibular asymmetry.

Chinese Journal of Medical Aesthetics and Cosmetology.2002;0(02):-.

Objective To explore a surgical procedure of reduction mammary plasty to assure the viability and sensory of the nipple-areolar complex (NAC) after transposition and to keep the lactiferous function partly. Methods Reduction was accomplished by using perforating vascular branches from the pectoralis major muscle and its fascia supplying the nipple and breast parenchyma instead of the subdermal plexus. The central vascular pedicle supplying the nipple-areola complex was preserved. And the sensory nerve of the NAC was not injured. The erection of the nipple could be observed in operation. Lactation was possible because of preservation of the lactiferous ducts. The technique had been used in 17 patients since 1996. Results The nipple-areola complex was safely transposed with great freedom, and the amount of resection was accurately adjusted for symmetry. No cases of nipple-areola complex sensory change occurred postoperatively in all 17 patients. Breast-feeding was possible at least in one patient after operation. Conclusion This method is ideal for the patients, which keeps the viability and sensory of the nipple-areolar complex and the function of lactation. In another case, the amount of resection is easily adjusted for symmetry.

Objective To present a method for breast reconstruction with the deep inferior epigastric perforator (DIEP) flap and to summarize the operative experiences. Methods DIEP flaps were elevated without carrying rectus abdominis muscle. The breast was shaped after the deep inferior epigastric artery and vein were anastomosed to the internal mammary artery and vein. Results Since 2000, we have used the DIEP flaps in 15 cases of breast reconstruction. There were 100 % survival in 10 flaps, distal skin necrosis in 2 flaps, and a full loss in 2 flaps. With the follow-up of 6～12 months, the reconstructed breasts were well-shaped and there were no complications such as abdominal heria, bulge and weakness in donor sites. Conclusion DIEP flap is the development and refinement of TRAM flap and possesses of advantages such as rich blood supply, abundant tissue volume, minimal donor site morbidity and easy shaping. It is a new but reliable and safe technique for autologous breast reconstruction.
