Cost and type of procedure needed for removal of a thick fat pad left over from big weight loss. Advice? (photos)

From your photos I recommend continue weight loss . Once you reach you goal weight excision of the excess skin and liposculpture.

Ikorodu73.   I appreciate your concern and good job with the weight-loss. First off, achieve your target weight and stay at that weight for several months prior to undergoing surgery. As long as you do not have redundant skin of your lower abdomen, liposuction and skin resection of the pubic area above your penis appears to be your best option. Seek the advice of a board-certified plastic surgeon in your region to explore all options. Good luck. 

 First stabilize your weight. After that it is likely that there will be excess skin which is more than what is  shown in the photo. You will probably need removal of excess skin and perhaps some reduction of fat in the pubic area. The procedure is  not complicated and can be done easily by a  board  certified plastic surgeon. The cost will vary according to the extent of the surgery.

Thank you for your question.  Continue with weight loss until you get to you desired weight or as close as you can achieve.  From the photo it doesn't appear that you have lose hanging skin so it is possible that liposuction alone will achieve your goals.  If you have some lose skin after weight loss then possibly you will need excision of the lose skin also but it looks to me that you will be able to achieve what's possible sugically with liposuction alone.
