Can I Just Get the Platsymal/corset-tightening Neck Lift Done on Its Own, Without a Facelift?

       Pictures or an exam would help elucidate what is needed, but what you describe does not represent a possible scenario.  Find a plastic surgeon who performs hundreds of facial procedures and neck lifts each year.  Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results.

It is certainly possible that a more limited approach to improve your neck laxity may address your concerns.  Without photos and an exam it is difficult to determine the extent of surgery necessary.  Facial and neck rejuvenation is best tailored to each individual as you will have a unique combination of platysmal laxity, skin laxity and fatty fullness.  A second opinion regarding your needs may help clarify the matter.  Good luck!
