Abdominoplasty combined with liposuction is the main treatment method for abdominal wall laxity. Abdominoplasty with concomitant liposuction removes excess subcutaneous fat through liposuction, which not only enhances the shaping effect, but also creates a good subcutaneous surgical dissection layer and avoids excessive damage to the perforating vessels of the abdominal wall, thereby reducing the incidence of high complications such as hematoma and skin necrosis that are easily seen after traditional abdominoplasty.With the development of weight loss surgery, the demand for abdominoplasty is increasing, and certain progress has been made in abdominal anatomy, abdominal wall aesthetics and abdominal wall plastic surgery techniques. This article summarizes the progress in the clinical treatment of abdominal wall laxity.

Objective To evaluate the clinical effect of nanofat on superficial rhytides of face and neck and dark lower eyelids.Methods From September 2014 to January 2017,a total of 86 cases were collected in our hospital for voluntary nanofat transplantation on superficial rhytides and dark lower eyelids.This was a retrospective study,which included 18 cases of eye wrinkles,14 cases of forehead wrinkles,neck wrinkles in 14 cases,and 22 cases of dark lower eyelids.First of all,we harvested mircofat through liposuction,and then transformed mircofat to nanofat.At last,nanofat was grafted into intradermal layer of the skin with sharp needles.We took the standard photographs of the patients.After six months follow-up,doctors and patients evaluated the short term and long-term postoperative effect.Results No serious complications occurred in all patients.Postoperative evaluation of facial and neck superficial wrinkles showed that the satisfactory rate of doctors and patients after one month,was 85.9％and 84.3％,and after 6 months 87.5％ and 84.3％,respectively.Postoperative evaluation of dark lower eyelids showed that the satisfactory rate of doctors and patients after one month was 45.5％ and 36.4％,and after 6 months 81.8％ and 86.4％,respectively.Conclusions Nanofat can rectify the superficial rhytides of face and neck and dark lower eyelids in some patients.However,for some patients the effect is not satisfied.
