Objective: To investigate the application of facial liposuction and fat grafting in the remodeling of facial contour., Methods: From Nov. 2008 to Mar. 2014, 49 cases received facial liposuction and fat grafting to improve facial contours. Subcutaneous facial liposuction with tumescent technique and chin fat grafting were performed in all the cases, buccal fat pad excision of fat in 7 cases, the masseter injection of botulinum toxin type A in 9 cases, temporal fat grafting in 25 cases, forehead fat grafting in 15 cases., Results: Marked improvement was achieved in all the patients with stable results during the follow-up period of 6 - 24 months. Complications, such as asymmetric, unsmooth and sagging were retreated with acceptance results., Conclusion: Combination application of liposuction and fat grafting can effectively and easily improve the facial contour with low risk.

Objective: To study the mechanism of treatment of post liposuction seroma with Staphylococcal enterotoxin C injection., Methods: 64 cases with post liposuction seroma were treated with Staphylococcal enterotoxin C injection or routine procedures. The exudate of those patients was collected to analyze the ratio, pH value, cell species and numbers, and the value of TP, ALP, LDH, AST, ALT, gamma-GT, ADA, ApoB, TC., Results: The ratio, numbers of lymphocyte and mesothelial cells and TP, LDH, ADA, TC value in exudate in Staphylococcal enterotoxin C group were significantly higher than those in control group., Conclusions: The effect of Staphylococcal enterotoxin C injection on the exudate of seroma may be related to the non-inflammation reaction.

Objective: To compare the effects of the external ultrasonic, the internal ultrasonic and simple negative pressure liposuction operations under tumescent anesthesia., Methods: The fat volume, operative time, complications and other indexes of liposuction in 276 cases were collected and compared., Results: External ultrasonic liposuction rapidly emulsified the fat with the least complication. The effects of the internal ultrasonic liposuction was next to the external ultrasonic method while the simple negative pressure liposuction had the poorest effects., Conclusion: The external ultrasonic liposuction operation is a safe and effective method for local overweight reduction.

The purpose of this experiment was to investigate how the tumescent technique reduces complications in liposuction. Histologic examinations revealed that the septa of fat are attached to the deep surface of the dermis and to the fascia superficialis. It is important to retain the septa that contain the perforating vessels and nerves during liposuction. The correct choices for instrument and suction pump can minimize trauma to tissues and reduce complications.
