RESUMO
Objective:To investigate the causes and treatment of implant malposition after breast augmentation surgery.Methods:A retrospective study was conducted to investigate the patients with implant malposition after breast augmentation treated or consulted in our department from January 2000 to December 2020. A total of 95 breasts in 74 patients were treated during the period. The age of the patients was from 19-50 years, with the mean of 31.2 years. Causes of these complications were analyzed and the patients were managed in different ways according to the times after primary breast augmentation.Results:Twenty-one malposition breasts occurred within one week after primary surgery, and 17 breasts were successfully treated with manual reduction and fixation. 4 breasts were treated with operation after failed with manual reduction. The patients had good and bilateral symmetric breast morphology during the 6 months follow-up after the second operation. 25 malposition breasts were treated from one week to one month after primary surgery. Reoperation was performed through the original incision, separating the adhesive cavity to reposition the implant. Those patients were successfully treated. No re-occurrence was detected at 6 months follow-up after treatment. 49 malposition breasts were treated more than 3 months after primary surgery. Excessive capsule wrapping the shifted implant was removed to recreate a fresh wound while the adhesive cavity was separated to reset the implant. Bandage fixation was necessary. 7 implants were exchanged. 2 breasts were over corrected and re-operated successfully.Conclusions:The causes of implant malposition at different time after breast augmentation are various. Different methods can be used for effective treatment.
