ABSTRACT
Objective To evaluate the results of prosthesis augmentation,relieve suffering patient experience,improve shape and touch of breast.Methods According to design,in dual-plane mammaplasty transaxillary approach with endoscopic assistance,we used soft-tissue expansion before prosthesis,saline volume in expander was the same as prosthesis size at beginning; adjusting expander volume and position,then determined prosthesis size according to expander volume lastly.after intraoperative sustained expansion for 30 to 60 minutes twice prosthes volume,replace expander with prosthesis.Results This method was applied in 120 patients,showing that pain significantly reduced after expansive without use of analgesia pump; complications included that 3 patients appeared seroma and absorbed soon; 2 patients had poor prosthese location,which was adjusted in reoperation; one capsular contracture was repaired later.After 6-months to 2-years follow-up,the results showed that breast was nature and dynamic; satisfactory rate reached to 95 ％.Conclusions In augmentation mammaplastic operation,pre-adoption of an expander can make it easy to adjust the location of prosthesis,to avoid being injured and to determine prosthesis volume by expander injection of saline volume,especially for patient with different size of both breasts.
