Breast Implant Damage After Car Accident

From your photo, it looks like you may have a history of mild to moderate capsular contractures (scar tissue) on both sides. This shows up as firmness of the breasts, visible definition of the roundness of the implant, and oftentimes a higher, less saggy looking breast. Some patients like mild contractures when they are symmetric. Trauma to the chest can potentially "tear" part of the capsule (scar tissue), which subsequently releases it, so the breast then feels much softer and looks potentially lower or more ptotic (saggy). This is usually associated with mild transient bruising  and swelling  on the affected side and discomfort at the time of the injury which resolves. In addition, the implant can rupture. If the device is silicone, the best way to diagnose a rupture would be MRI. With saline, you usually see a size decrease. Regardless, the visible asymmetry in your central cleavage area, which shows in clothes, likely will need to be corrected with surgery if you don't see improvements with conservative treatment such as massage over a few months.

VVN,
Your description of your breast augmentation history and your recent trauma with subsequent change in the breast begs the question of whether the implant was damaged during the accident.
Seven or eight months out from surgery is an unusual time for one implant to suddenly drop. Usually, most of the implant settling has occurred by six months. I'm not sure what the 5,000 damage means, as a small amount of damage can cost a lot of money these days.
You don't mention whether you received any trauma to your breast in the accident. An impact strong enough to damage an implant would likely cause you pain and bruising in the breast. I suggest that you return to your surgeon for a full evaluation and advice as to how to correct the asymmetry in your breasts. Good luck!

VVN,
It is hard to tell from your description if the car accident had anything to do with it. If you were not hit in the breast area or had any force from the seatbelt on the breast region, then it is hard to say it was from the accident. However, any unilateral (one sided) change is curious and you should see your surgeon for an evaluation. Good luck.
