Do sutures hold the platysma in place until muscles are fully healed?

I assume you are referring to platysmaplasty--procedure performed to bring the left and right parts of a platysma are brought together. This can be done with either permanent or absorbable suture; after 2-3 months and probably sooner, the muscles have scarred together enough that the suture is no longer really needed. This is why many surgeons use absorbable suture for this repair. Hope that helps!

During a platysmaplasty procedure, the aim is to tighten and reposition the platysma muscles in the neck to create a smoother and more youthful appearance. The surgeon typically sutures the platysma muscles together to hold them in their new position and provide support during the healing process.

The sutures are intended to keep the muscles in place while they heal and scar tissue forms, effectively maintaining the desired contour and tightening of the neck. Over time, the body's natural healing processes help the muscles to adhere in their new position, making the sutures less critical as the scar tissue stabilizes the muscles.

While complications and risks are possible with any surgical procedure, the risk of the platysma sutures coming undone is generally low. Surgeons use techniques and materials designed to minimize the chances of suture failure. It's essential to follow post-operative care instructions carefully and have regular follow-up appointments with your surgeon to ensure proper healing and address any concerns that may arise during the recovery process.

I hope this helps,
best of luck !
