Is there anything that can be done about my sloping/sagging neck? (Photos)

Improving your neck angle can be achieved in a number of ways.  I like to use Precision TX, which is laser-assisted liposuction and skin tightening. In some cases, I perform a platysmaplasty using an incision under the chin. In either technique, fat is removed in order to improve the contour. Some of the "non-surgical" methods may not be adequate to achieve the result you're seeking.  I wish you the best.

It's best to begin by consulting with a surgeon in-person to discuss your options. Depending on the level of laxity, the effects of a neck lift will certainly outlast the effects of non-surgical treatments. Non-surgical procedures can only temporary resolve the issue and require few to several attempts or treatment appointments. The presence of banding down the front of the #neck, and, amount of excess skin and condition of your skin are among some factors which determine if you are a #candidate for #rejuvenating the neck.
During your initial examination, your chin will be evaluated along with the neck and jawline. A weak #chin implies a lack of chin support for the skin along the neck line. In younger individuals a chin implant alone is usually all that is needed to improve the appearance of the neck. Subsequently, it will also improve the overall #balance of the face and can create the illusion of a smaller nose. As a stand-alone procedure, chin augmentation can be performed in the office under local #anesthesia. For individuals with signs of #aging in the neck, a chin implant added to one of the recommended procedures above, will provide optimal results.
If you are not a candidate at the time of your #consultation, your board certified plastic surgeon can recommend alternatives to address your concern. Consulting with a board-certified plastic surgeon who specializes in #neck lift procedures is important to ensure you are receiving the best advice, care, and surgical experience possible.

it is not uncommon for a man to get a little neck tuck under local called a platysmaplasty and is easy to undergo.

It appears that you have a familiar obtuse neck. Anatomical distribution of neck muscles and fat compartments is most likely reason for that. In order to correct current deformity anterior neck lift would be an option. It involves removal of superficial fat compartment (above neck muscles) that seem to be a major contributor to your neck deformity as well as shaping of deep fat compartment located between deeper muscles of the neck. It is possible that some revision of deep neck muscles (digastric muscles) may be needed. Without in-person exam it would be hard to tell you whether all of this can be achieved through a submental (bellow chin) incision. It is possible that small chin implant would further improve neck-chin balance.

Patients in the late 30s that have loose skin in their neck could benefit from a carefully done neck lift. This procedure will tighten the neck muscle, correct the neck skin laxity and remove the excess of fat under the chin. 

Thank you for your question. Laser rejuvenation technology can shrink the excess tissues and skin of the neck to restore taut jaw and neckline. A chin implant will counterbalance your neck by creating a more prominent appearance. I suggest that you move forward and consult with a board certified facial plastic surgeon.
Best wishes,

Thanks for sharing. At your age, I believe chin lipo with a platysmaplasty would address the concerns you have.  This can be performed with just an incision below your chin and at times also a small incision behind each ear lobe. A chin implant would further enhance your results.  

a chin implant with conservative liposuction will improve your facial balance now. A facelift can wait for awhile. 

I find that VASER liposuction in combination with ThermiRF are best for contouring the chin in those who are candidates but Kybella can be used as an alternative with or without thermage/ultherapy/exilis or coolsculpting.  PDO nova threads can further improve the jawline, while a chin implant would give more definition. See an expert. Best.

Dear patient, thanks for your question!  A neck lift will help you with the issue of the sagging/sloping neck.  A Board Certified Plastic Surgeon would help you with tightening the skin of your neck and giving you the new profile you desire.  You can discuss the possibility of a chin implant as well.  Hope this helps!
