10 months post op facelift & necklift - bad result and why still swollen? (Photo)

It does take time for swelling to abate.  However, 10 months is a lot of time.  A neck revision with ptatysma transection and skin repositioning would be helpful.  Would need to see you to stand behind that statement.

By the 10-month mark, the results
you see now are likely permanent. Although I don't think your overall results
are "bad," I can certainly see room for improvement in the form of a
platysmaplasty to further smooth and refine your neck. Ongoing swelling could
indicate fluid buildup, which your surgeon can help you resolve. I wish you
well as you navigate this next step.

I'm sorry to read that you
are disappointed with your results. At 10 months, the swelling should have
resolved, so now is an appropriate time to consider revision. You do have
submental fullness, as well as platysmal banding. Transecting the playtsmal
bands when you have other issues runs the risk of more irregularities. I would
favor a more complete revision from a lateral approach to deal with the
submental fullness and tighten the platysma, possibly together with a medial
platysmaplasty and selective platysmal transection. Platysmal banding can be
challenging to deal with on its own, but your problem is more extensive.
Transection of the platysma bands is enticing in terms of its simplicity, but
in more complex situations, I have found the procedure to be unpredictable.
Best wishes.

Elevating the neck skin along the entire neck and suturing the platysma band edges together with transection of the ones you see in animation should do the trick.  No further defatting of the neck should be done as this could lead to a deep indentation in the midline. 

Thank you for your question.  Yes, I believe that most of the swelling from surgery should be gone by now.  From the pictures that your have posted, I do see some fullness under the chin and some platysmal banding.  I usually do not recommend transecting the platysma as a first-line solution.  You may be a candidate for a revision of the submental area and the platysma, as well.  Discuss your concerns with your surgeon.  Be sure to seek out consultation from a board certified facial plastic or general plastic surgeon who specializes in face and neck lifts. I hope that this helps!-David Gilpin
