I have been away for a late summer break, and it is interesting to read the answers that have already been posted. All of them have value, but here are my thoughts.While it is true that both permanent and resorbable/dissolving can be and are used, and that both braided and mono, similarly, are acceptable alternatives, there are a few things that influence my thinking.First, the platsyma in many, not all patients, doesn't have a lot of strength, especially in the central neck. Back in the area below the angle of the jaw, the overlying fascia gives it more, and its continuity with the upper SMAS makes suturing under some tension a more realistic matter.This is important, because anywhere sutures are placed with tension, they will gradually cut through the tissues, just as a wire cuts through cheese or in the old days, blocks of ice were cut.This means the use of permanent sutures in many locations is of doubtful benefit. There is a race between the healing with strength of the wound, and the breakdown of absorbable sutures and loss of their strength or the pull-through of permanent sutures. We hope the healing has progressed enough before the other factors kick in.As a result, tension is one the most important factors in determining success or failure, and just pulling the muscle together isn't a recipe for success.When I do a midline platysmal repair, I usually use two layers of braided absorbable, and try to mobilize the muscle enough to repair it with very modest tension. I make transfers, low relaxing incisions ( myotomies) to prevent shortening the vertical dimension and "bowstringing" of the muscle which blunts rather than emphasizes the neck to jaw angle.In fact, many of us have stopped doing routine midline platsymaplasty because regardless of the suture material or specific surgical technique, recurrent platysmal bands occur with disappointing frequency, even in the best of hands. Furthermore, significant improvement can be achieved with careful SMAS/ platysmal elevation and mobilization from behind, sometimes with "closed myotomies" or division of the bands as an adjunct.
