I was in a accident when I was 9 and broke my nose and the bone under my eye I didn't do corrective surgery then and now I'm 36 and one eye the fractured side has a puffy bag under it so I have one puffy eye how much would it cost to fix it?
To take out the lower eyelid fat pad and to improve any skin redundancy issues will require a lower eyelid blepharoplasty. If you only need fat pad removed, this can be performed using a transconjunctival approach. You should consider a consultation with an eye specialist to get an accurate estimate. Rough estimate range 3 to 6K$.
You didn't mention your age but most likely you need some fat removed and a little skin, a lower blepharoplasty on one side. It will vary widely depending on where you live. In the DC metro area, lower lid blepharoplasty would be about
$3500, including surgery and anesthesia fees in a private office OR. It would be an additional $1000 more for a hospital setting.
