Disappointed with Tummy Tuck results. How to express this to doctor without insulting him but getting my point across? (Photos)

this is likely a mixture of problems on both sides. Your surgeon likely didn't explain to you what type of result you could expect while you have unrealistic expectations(the sitting photo, everyone's abdomen will look terrible, even many think girls who haven't had or need a TT). Your BB in a little large, looks like you could benefit from more lipo, your skin appears fairly tight in a standing position, so more skin may be hard to be removed but realize that will then leave you will a scar where your BB is now. Honest conversation with open mind is your best bet. Good luck

It's best to simply be straightforward and explain your concerns.  Looking at your photos, aside from the belly button being a little enlarged, I frankly do not see any problems.  Perhaps your goals were not met, you and your surgeon did not clearly explain to each other what you wanted and what the surgeon could achieve?No need to feel embarrassed, speak to your surgeon.  Lack of communication is the biggest source of conflict.

Thank you for sharing your question and I am sorry that your current results have not been what you anticipated.  I would recommend evaluating your preoperative and postoperative photographs with your surgeon while reviewing the records of your desired result at the time of your initial consultation.  Comparison of the desired verbal results can then be done to your current surgical ones and treatment options at improvement can then be had to discuss how refinement of your results can be addressed.  Hope this helps.
