Does anyone know how to get rid of these protruding neck cords that appeared after a necklift? (Photos)

You need a necklift pure and simple.  Search out surgeons who do a "corset" platysma plasty in their necklift procedure as you need the muscle tightened and the skin tightened too.   All the other options your listed will not change your anatomy to the degree you need to have a smooth neck.  Best Wishes!!

There appear sever platysmal band contracture and scarring after your initial surgery. Since it has been 18 years since initial surgery, the best treatment is revision surgery.

you really need addtiional surgery to tighten the neck muscles.  Non invasive options like botox, ultherapy etc will not be enough to give you the improvement you are looking for.  Best, Dr. Emer.

You will likely need an additional revision, in view of failure of conservative measures. It would be nice to know what was done in the past. Our office usually gets good results on platysmal bands in revision cases, but an exam is needed and an experienced surgeon should be able to handle this case.

As you have learned over the years, this is a difficult and frustrating problem and is not easily corrected because of the great degree of scar tissue built up over the years from the multiple treatments.While this MIGHT be improved with a revisional necklift, this would be more difficult and risky than a previously unoperated neck because of the scar tissue.You should have a formal consultation from board certified plastic surgeons who have experience with difficult neck problems such as this, and be sure to  bring all of your previous operative reports and procedure records with you to those consultaionsAsk to see results of previous similar problems they have treated, and discuss risks and expectation carefully before making any decision,

You can try botox, but if it's not muscular, but rather scar or soft tissue, then you will require additional procedures.  You can reopen the area and dissect either minimally with liposuction and/or more involved to redistribute the tissue and eradicate the cords.  You could do no surgical interventions such as radiofrequency ,(Fractora), which is quite effective in the neck region, or possibly ulthera (ultrasound based therapy).  A visit with a plastic surgeon would be helpful to examine and answer your questions regarding options.

Hello Strobelight,Your pictures are consistent with either scar tissue that has developed there or that can also be seen when the edges of the muscle that created the original bands are sewn together.  You mentioned multiple treatmetns and attempts at improving them.  Botox would help with an active muscle.  Since that looks more like a scar, I would not anticipate Botox would help.  Steroids work better on a scar that is healing as opposed to a mature scar.  Surgery may be an option, but it may also form more scar tissue.  But surgery would allow you to then begin steroid injections on a healing scar.  As there is no perfect solution for your problem given the fact that previous treatments didn't work, it is important to realize that any future treatment may also not work.  There are options available, such as surgery, but it is no guaranty it will solve the problem.  I'd recommend you consult with a facial plastic surgeon to discuss the options, the likelihood of success, and learn more about the optionsI hope this helps and good luck.  

On the basis of these pictures the cords are probably secondary to residual platysma muscles bands requiring revision surgery. If Botox has been properly injected without success some scar tissue may be present. An examination is necessary to determine the cause of these unwanted bands before recommending treatment.
