Any Hope for a Ropy Looking Neck?

Without photos, it's difficult to determine the treatment to address your concern. Also, it really depends on the amount of #sagging you are experiencing. It's best to begin by consulting with a surgeon in-person. 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 what treatments will best rejuvenate your 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.
Your board certified plastic surgeon should evaluate both your anatomical features and aesthetic goals to suggest which procedure best suits your needs. In some cases there may be more than one option to choose from. If you are not a candidate at the time of your #consultation, your board surgeon can recommend #non-surgical alternatives to address your concern. 

Those bands are the anterior border of the platysma muscle, a sheetlike muscle that runs across the neck and jawline.  With age, they sag and pull away from the deeper attachments in the neck, and the overlying skin does something similar.  There is only one solution, which is surgery.  Botox is described and performed, but rarely is worth the money, and the results are not always impressive since the skin remains an uncorrected component.

I also agree with the other surgeons that you require a straightforward facelift, which includes an incision and correction of the midline issues with excess muscle resection and suture reapproximation (anterior plication), and then posterior repositioning as well.  Anything less will leave you with incomplete correction.  Whether or not the surgeon proposes even more, like a muscle relaxing cut in midline, or complete platsymal transection, or neither, is just surgeon preference.

The vertical bands of the platysma muscle need to be tightened together with a neck/facelfit. For those patients who are adamant not to undergo surgery, Botox or Dysport can help flatten them slightly but this is temporary and the treatment ongoing, and there are risks that you would need to discuss with your doctor such as weakness of the neck and even swallowing if very rare cases.

These should be addressed with a full face lift where the band are excised and the remaining muscle forms a sling. If you just try to do a minilift of some name, they WILL recur.

It sound slike you have loose skin and platysma banding but I can not e sure unless I examine you. If this is the case, then a neck lift or facelift with neck lift can give you the results you desire.
