The tissue expander filled too fast. Why? (photos)

I am sorry to hear about your implant exposure. There are many reasons for implants to become exposed. It is unlikely that filling too quickly would be the culprit. It is generally due to poor wound healing, thin skin flaps as a result of the mastectomy, or fluid around the expander. Thank you for sharing your experience. I hope that by discussing this, and receiving advice, you can better feel comforted as your move forward to the next stage of your reconstruction. For now, I hope you heal well. Keep your nutrition optimized, and follow the instruction of your plastic surgeon.I hope this helps.- Dr. Bryson Richards

Dealing with an exposed tissue expander can be complicated. Not knowing the full history it is difficult to comment. Best of luck.
