title: Regrowth of platysma following platysma cervical lift: etiology and methodology of prevention.
abstract: Platysma regrowth after platysma cervical lift is a new complication. We postulate that the platysma reestablishes itself by hypertrophy of muscle fibers contained in its posterior SMAS sheath as well as by muscle regrowth along the posterior sheath. We now routinely cut both platysma and posterior sheath. We also recommend excision of anterior platysma not connected to the posterior sheath. Closure of platysma should be from the mentum to the upper thyroid cartilage utilizing nonabsorbable sutures.
