Prominent mons pubis 6-1/2 months after Abdominoplasty. It's the same as it was at 6 weeks. Can it still be swelling? (photos)

At this point, it is probably not related to swelling.  More likely, it is some fat that will respond to a little bit of liposuction in the area, which will help to recontour it to match the tummy area.

Speak to your surgeon about this option.

At this point, the majority of swelling has certainly resolved but ongoing improvement in the size/shape of the pubic area is certainly possible over the course of the next several months.  Therefore, I would suggest ongoing patience. Having said that, given your concerns, it is likely that additional liposuction surgery and/or skin excision will be helpful when it comes to improving your outcome. Best to communicate your concern/question directly with your plastic surgeon, preferably in front of a full length mirror.  Working together you will come up with a good plan to proceed with. Best wishes.

If not a fluid collection, then a little lipo by your surgeon may be appropriate. It can be done awake with just a local anesthetic.
