Will scar tissue from a traumatic parathyroidectomy and thyroid surgery interfere with repair of playtamus?

Neck scars from previous surgeries like thyroid surgery or parathyroid surgery could potentially interfere with the realization of a neck lift. However, most of the time, there is no problem for an skilled neck lift plastic surgeon to overcome the scar and perform to satisfaction the neck lift procedure. 

In most cases, a thyroid or parathyroid scar in the lower neck will not significantly affect the outcome of a surgical necklift or facelift procedure. That being said, each patient is unique, so make sure to discuss these concerns with your surgeon during your consultation. He or she should be able to examine you in order to determine how much laxity is present and how it is affected by the scar tissue. 
All the best,

Hello,
Typically, scars from operations such as thyroid surgery or cervical spine surgery do not interfere with the platysmaplasty operation or its results.  As long as your surgeon has performed a thorough evaluation of your neck and determined a good course of action you should have excellent results.
Regards,

When each of my patients come for consultation, I take a thorough history and examination before discussing treatment options. This includes previous surgeries and scars that may be involved in future treatments. This is something to consider, but it does not often change your options to improve the shape of your neck. Please bring up details with your surgeon so they can provide a safe and happy surgery. Safety comes first. 

I agree with my colleague that scars from thyroid or parathyroid surgery rarely interfere with our ability to perform a neck lift and repair the dehiscence of the muscle.  At the time of the endocrine surgery, the dissection likely affected the blood supply to the surrounding skin, so the more remote the neck surgery the better.  Please consider discussing your concerns with a Board Certified Plastic Surgeon in a formal consultation.  While your photos are limited, it does appear that you have laxity above and along the jawline, so it may be worth considering a facelift or lower facelift, rather than just a neck lift.  Best of luck as you research your options.

Previous scars, especially when mature, typically do not interfere with neck lifting surgery.  There may be some additional scar tissue under the skin at the scar site, which may require a bit more dissection and work on the surgeon's part, but ultimately the incision shown in the photos should not negatively impact the outcome of neck rejuvenation surgery.  The scar may be elevated and slightly more visible when the overlying excess skin is redraped and tightened.  Discuss your concerns with a plastic surgeon or facial plastic surgeon as part of a detailed consultation about your treatment options, and good luck!
