Do older women (60+) who have facelifts still need dermal filler injections after the surgery?

At your age you are probably a good candidate for a facelift.  Have the facelift first and then you can decide on whether fillers are also worthwhile.  You may be so pleased with the result from the facelift that you don't find that fillers are necessary.

Aging is multifactorial and multidimensional.  Although the answer is somewhat subjective based on your tolerance for aging, facelift and fillers really have different results and endpoints.  However, if you have the signs of aging such as midface descent, jowls, and obliquity in your neck, facelift is the only procedure which will comprehensively address these problem.  Likewise, if you have such concerns addressed with a facelift, teh signs of aging addressed by fillers may be less of a priority for you.

Most facelifts obviate the need for fillers. However is time passes there may be some contour issues that would benefit from the use of these adjunctive therapies.

Dermal fillers and facelifts are really addressing different issues, and if you want to look your very best you will likely need to continue addressing your skin and volume loss even after a facelift.

Surgical face and necklifting would help to shape the face and neck on a larger scale, while nonsurgical or minimally invasive procedures such as Botulinum injections, laser or chemical peels, fillers, and medical-grade skin care products would be used synergistically with surgery to reduce the appearance of wrinkles, age/sun spots, and volume loss. These minimally invasive treatments can be undertaken either before or after surgery. If performed before surgery, these treatments can provide enough rejuvenation for many patients to delay or avoid surgery. However, for patients wishing to pursue more dramatic rejuvenation, especially in cases where gravity or laxity plays more of a role in the aging issues, surgery is typically undertaken first to help set the foundation for the face and neck, and fillers and other minimally invasive treatments are performed afterward to treat and maintain areas not addressed by surgical lifting.
