Droopy eyelid 1 week after chalazion removal! Is this permanent especially that I had ptosis surgery last year? (Photo)

The swelling associated with the chalazia and the surgery, will weigh the eyelid down.  The ptosis may resolve when all of the swelling settles down.  This can take 6 to 12 months.  At the end of that process, it is possible that the eyelid will end up being droopy and require revisional surgery.  That surgery should not even be remotely considered until you have healed a full 12 months.

Best to discuss with your surgeon and allow proper healing which can take up to 3 months before re-evaluating the eyelid position.

if it persists see an ophthalmic plastic surgeon as they are more qualified than most facial or general plastic surgeons in dealing with eyelid ptosis, even more so since it is recurrent.
