Hi Danielle1231,
Very strong platysmal bands ( the vertical muscle bands of the neck) can be difficult to treat. For people who are reading along, who don't understand what neck muscle bands are referring to the edge of the muscle in the neck (the platysma muscle) tents through the skin like a clotheline hidden under a bedsheet. As you pull the clothesline tight, the bedsheet appears to have a band running through it. In my experience, patients who have muscle bands which protrude actively while talking or making facial expressions, can have remaining muscle bands showing after a platysmaplasty. When the patient is relaxed and not talking, or smiling, the platysmal muscle band appears flatter, and not prominent. However, since most people are animated when having a conversation with another person, the patients who have prominent muscle bands will complain that their muscle bands are not flattened enough.
The platysmaplasty will help to tighten the platysma muscle directly under the chin, to create a longer distance from the tip of the chin to the beginning of the neck. If the platysma muscle is simply hanging down passively the platysma muscle band can lay flat against the neck. For patients with prominent muscle bands which actively contract, I warn them prior to the necklift that they may have some residual muscle bands showing. In order for the muscle band not to affect the profile of the neck. I routinely make a cut into the platysma muscle band where the corset platysmaplasty stitches end. I will cut between 1/2 -3/4" into the muscle and try to remove a small triangle of the muscle, to prevent the muscle from healing itself together.
If I perform this backcut into the edge of the platysma muscle it helps to flatten out the platysma muscle band towards the center of the neck, but if the patient's platysma muscle is extremely strong, a new band may form away from the center of the neck towards where the cut edge of the platysma muscle ends. In essence the new edge of the platysma muscle is where the muscle is continuous from the tip of the chin to the collar bone. Using the clothesline and bedsheet analogy, it would be like cutting the clothesline, and the bedsheet will flatten out since it is no longer tethered on the clothesline.
There are more aggressive methods of cutting the platysma muscle of 1-2", however, I have not needed to do this on my patients. It seems to be much more aggressive modification of normal anatomy, as opposed to a 1/2-3/4" notch on the muscle edge. Not every patient would benefit from this kind of platysma muscle transection or cutting, but perhaps you may be the exception.
One other method, to consider is the Giampappa stitch. I have use this in the past for patients with difficult, heavy necks. It uses a permanent suture or thread similar to fishing line, which goes from the back of one ear to the back of the other ear. Because this suture is permanent, it could potentially help flatten out the platysmal muscle band from actively protruding out. I'm not sure if the GIampappa stitch is designed to treat strong platysma muscle bands, but if I had a patient with strong muscle bands, I would likely perform a longer notch on the edge of the platysma muscle and add the Giamapappa stitch for treatment of the muscle bands. In layman's terms, it would be like wearing both a "belt and suspenders" to hold up the pants. Each method backs up the other.
I hope this explanation helps.
Best,
Dr. Yang
