Had facelift and neck lift. Left with jowls and square man like face

Thank you for the question/concerns. Depending on how far out you are after the surgery, much of this may be residual swelling. Swelling is affected by gravity, so if there is fluid in the tissues, this may be more apparent along the jawline and immediately under the chin. That said, if you are healed and have residual issues, you may need some revision work. Please check in with your surgeon. If you don't feel comfortable with that, please get a second opinion from a surgeon specializing in facial cosmetic surgery. Take care.

Depending on how long ago your procedure was, it may just be due to swelling. It's important to follow up and stay in contact with your surgeon who can guide you through what to expect in your healing process. 

Thank you for sharing your question and I am sorry that your results have not been what you anticipated.  Unfortunately without a full series of before and after photographs, with associated timing of recovery, it is difficult to offer definite advice.  I would recommend seeing your surgeon and voicing your concerns, they should be able to provide you with reassurance or methods of improvement.  Hope this helps.
