Thank you for your question. In my experience Removal of a breast implant hematoma, cleansing of the pocket with antibiotic solutions and replacement of the breast implant has actually led to quicker healing and a better ultimate result than the untreated side. I believe the benefit of removing blood and all tissue fluid around the implant and reinserting the implant actually has a beneficial effect on your healing.
Treatment of a hematoma after a breast augmentation expectantly leads to higher rate of capsular contracture. Proper treatment is removal of the blood from the pocket, cleansing the pocket, and reinserting the prosthesis.
In my experience, when the hematoma is treated immediately, full evacuation of all blood, control of whatever is bleeding and antibiotic irrigation, there is no discernible effect of the final result.
Once the washout is performed( if caught early) and the incision is closed, I find in some cases there is some more swelling on the treated side but eventually it improves and matches the other side.
Your surgeon treated you well and appropriately in evacuating your hematoma, cleaning out the pocket, and replacement of your implant. Leaving the hematoma to absorb without surgery increases your chance for contracture, but a well performed evacuation should not. Additional bleeding post evacuation and careful control of any small bleeding points is rare.
