OBJECTIVETo improve a better method to achieve the upper arm's circumferential harmony by using adjacent aesthetic unit combined upper arm liposuction.

METHODSLiposuction of upper arm, axilla and part of the scapula area was performed on 88 cases at one stage from January 2007 to March 2013.

RESULTSAll the cases achieve satisfactory results. The circumferential curve is smooth and elegant. No severe complication happened.

CONCLUSIONSThis method proved to be safe and effective and can be accomplished in one stage.

OBJECTIVETo investigate the effect of the anticoagulants on PRP quality, so as to clarify the appropriate anticoagulant used in PRP production.

METHODSThe microstructure change of platelets collected via heparin, citrate, acid citrate dextrose (ACD) and citrate-theophylline-adenosine-dipyridamole ( CTAD) was observed by TEM following time course. The extent of spontaneous activation of platelets in four groups was detected by measuring sP-selectin in plasma. The TGF-β1 release amount of activated PRP of four groups was measured.

RESULTSCTAD is superior to other anticoagulants in maintaining the integrity of platelet structures for a long time and preventing platelet spontaneous activation. ACD slightly surpassed heparin and citrate in above two aspects. ACD-PRP and CTAD-PRP released significantly more TGF-β1 compared with heparin and citrate.

CONCLUSIONSThe PRP quality and biological effects were strongly associated with the type of Anticoagulants. ACD and CTAD are optimal anticoagulants in PRP production for they can maintain platelet viability at a high level.

Objective To explore the methodology of the preventing the absorption after autog-enous fat granule mammaplasty, and the main point of the operative methods.. Methods The clinical data were reviewed in 30 cases of patients with liposuction combined with fat-grafting injection for breast mammaplasty in the past four years. The tumescent technique was used in liposuction and the volume of fat tissue aspirated was between 500 ml and 3250 ml. Using appropriate way we prepared pure fat granules and then evenly injected into the layer beneath the pectoralis major muscle, submam-mary layer and subcutaneous layer of the breast, respectively. Results The effect of the method was satisfying because sucking area was significantly decreased. From six months to 10 months follow-up, grafts showed no obvious absorption. The breast looked symmetry. Conclusion Fat grafting injection is a practicable method for breast mammaplasty. The key point is to use appropriate way to get pure fat granule and to prevent infection. It deserves to be recommended.

OBJECTIVETo explain a method for lower face and anterior neck reconstruction.

METHODSTissue expanders were implanted subcutaneously beside the defect. When the skin was properly expanded, the bipedicled expanded skin flap was created and transferred to the lower face and the anterior neck. If the defect can not be repaired by one stage, the expanded skin was re-expanded for the rest.

RESULTS11 patients have been treated with this method since 1990. All flaps survived and all the defects have been successfully repaired with satisfactory results.

CONCLUSIONThe bipedicled expanded flap, which provided good blood supply, improved the survival rate of the flap and reduced the incision scar on the face, is an effective surgical procedure.

OBJECTIVETo evaluate the effect of external use of papaverine cream on enhancement of tissue expansion.

METHODS8 mini pigs were randomly divided into 4 groups. During inflation, papaverine was given externally in group A, through a delivery system in group B, though intramuscular injection in group C. Papaverine was not given in group D. The time of inflation, the expansion rate, the surviving length of expanded flaps and the papaverine concentration in the fibrous capsule in each group were examined. Histologic and electroscope examinations of the expanded tissue were made.

RESULTSThe average inflation time was 28.9 +/- 4.5 days in group A, 34.0 +/- 2.6 days in group B, 37.6 +/- 4.8 days in group C and 38.5 +/- 3.5 days in group D. There was significant difference between each group(P < 0.05). The average surviving length of expanded flaps in group A was 13.67 +/- 1.28 cm, 11.07 +/- 0.88 cm in group B, 10.79 +/- 0.49 cm in group C, and 9.49 +/- 0.77 cm in group D. There was significant difference between each group (P < 0.01). Histologic examinations of the expanded tissue suggested that there were no significant differences in thickness of epidermis, derma and fibrous capsule among the four groups. Electroscope examinations of the myofibroblast in fibrous capsule showed that there were smaller nuclei, fewer microfilaments and fewer mitochondrias and rougher endoplastic reticulume in group A than those in other groups. The concentration of papaverine in fibrous capsule of group A was 3.5 +/- 1.2 micrograms/g. Papaverine was detected neither in the skin of other groups nor in the blood of all groups.

CONCLUSIONS1. Papaverine cream can permeate through skin and maintain high concentration and continuous effect in local tissue. 2. External use of papaverine cream can inhabit the function of myofibroblast in fibrous capsule, increase inflation rate, accelerate expansion process, and improve microcirculation of the expanded skin with a result of prolongation of surviving length of expanded flaps. 3. The technique of enhancing tissue expansion with external use of papaverine has the advantages of convenient delivery, cheapness, no more injury and infection, and no side effects etc. It is a safe, effective, simple, and reliable method for accelerating tissue expansion.

Objective: To describe an extended whole upper limb liposuction technique and evaluate its clinical effect. Methods: 34 patients who underwent upper limb liposuction from February 2018 to February 2019 were selected and the clinical data were retrospectively summarized. Patients were treated with upper arm ring/upper arm ring + forearm 1/3 rings/whole arm ring aspiration combined with accessory mammary gland, armpit, scapula and other adjacent aesthetic parts of extended liposuction. The preoperative and postoperative maximum circumference, thickness of the anterior and posterior subcutaneous tissue and skin laxity were measured and compared. analysis of complications, and evaluation of patients′ satisfaction through satisfaction questionnaire. Results: The arm shape of all patients was significantly improved, the maximum circumference of the arm was reduced (16.2±4.0)%, the distance of the upper arm was reduced (29.5±8.9)%, the thickness of the posterior subcutaneous tissue was reduced (56.6 ±6.2)%, and the thickness of the anterior subcutaneous tissue was reduced (44.7±9.6)%. There were three cases of mild anemia after operation, and no other serious complications occurred. Patient satisfaction was very high. Conclusions This is an innovative arm liposuction technique with hidden incision. The effect of improvement is remarkable. The patient′s satisfaction is high.
