With simple removal of the implants, there should be little if any swelling, and that of short duration. If, for example, a complete removal of the capsule around the implant is done, there will be more swelling that can last for a month or so if all heals without event. All the best.
If just the implant is removed, swelling is minor and lasts a few days. If more work is done, like a capsule removal, then swelling may last a few weeks.
