8 days post op Thermitight under my chin. Should I still have this amount of swelling? (photos)

Having done a fair number of these procedures in my practice, I can say with good certainty that the amount of swelling I see in the photo is not at all unusual. Swelling will vary from patient to patient depending on the internal temperature used, the amount of time spent treating the area, and the tissue layers that are treated.  Treating just below the skin's surface (sub-dermal) does not typically result in much swelling. However, when the subcutaneous fat layer is also treated, it is fairly common to have some firm swelling in the area for up to 2 months. If the deep layer of fat is treated (under the platysma muscle) then swelling can be slightly longer in duration. I have found that circular massage is the most helpful maneuver for speeding resolution. If you develop a hard knot, your doctor may also consider injecting a dilute steroid to aid the process.

Thank you for the photo and your question. Though I do not have  a pre-treatment photo for comparison, the swelling that I see would be fairly normal after a ThermiTight procedure for the neck. This will resolve with time, though gentle compression and heat can be helpful. In my practice, we use a dressing similar to that for facelift patients. This is applied nightly for a week or so.

Although ThermiTight can tighten one's sagging neck without surgical cutting, it does involve introducing a thermal probe after local anesthetic is injected.  The heat tightens the tissues but swelling is caused and in my NYC practice, I have seen ThermiTight cause swelling that lasted two weeks, and in rare cases even more.  Bruising also can occur.  For the right candidate it is a procedure that can provide an excellent cosmetic result in neck and facial tightening and lifting without cutting or sutures being involved.

From your photo it does not look like too much swelling after a ThermiTight procedure -- that being said make sure you see the doctor that performed the procedure to assure that this is not a hematoma (accumulation of blood), seroma (accumulation of fluid), or infection, which would be very unlikely after a ThermiTight procedure.  Cool compresses are helpful to bring down soft tissue swelling after any kind of procedure.  

It is not at all unusual to have that amount swelling 8 days after the procedure. In my experience, swelling typically lasts 10 to 14 days. Swelling typically means that you obtained some tissue reaction which is what you desired from the procedure. This means that you will have some type of inflammatory healing response and hopefully that will tighten the tissue to your satisfaction. If you have any questions or concerns, I would encourage you to follow-up with the physician who performed the procedure. Hopefully he or she is a board-certified plastic surgeon certified by the American Board of Plastic Surgery. I wish you the best.
