Objective:To search for a safe

effective and convenient treatment for the complications after polyacrylamide hydrogel(PAHG)injection for augmentation mammaplasty.Methods:47 patients with complications after PAHG injection for augmentation mammaplasty were included.B type ultrasound detection was performed Preoperatively in order to find out the distribution of PAHG.After local anesthesia

a 10 mm incision was made at submammary fold of each patients.Under the guidance of endoscope

PAHG was rinsed by tumescent technique at low pressure and aspirated out for several times

until the capsule wall of PAHG was clean and the rinse solution was clear.The infiltrative tissue was excised.Negative pressure drainage tube and antibiotics were used postoperatively and the patients were followed for 5～20 weeks.Results:All incisions were primarily healed

leaving no hematoma or infection.All patients were satisfied with disappearance of pain in the breasts

soft mammary tissue without any noeud and no PAHG remains which was detected by B type ultrasound.Conclusion:Minimally Invasive endoscopic treatment for complications of PAHG injection for augmentation mammaplasty was characterized by its micro-incision

accurate operation

high PAHG clearance

minimal trauma of tissue and reliable hemostasis

worth to be widely used.
