Background: Aging changes in the neck, including platysma banding (PB), skin laxity (SL), and submandibular gland visibility (SGV), have a high degree of recurrence after rhytidectomy. Objectives: The authors sought to assess the long-term improvement in PB, SL, and SGV with addition of aplatysmal hammock flap to the extended deep-plane facelift and assess patient satisfaction. Methods: This was a prospective study of 123 consecutive patients undergoing extended deep-plane facelift incorporating platysma hammock flap with or without midline platysmaplasty. Standard 2-dimensional patient photographs were employed to assess PB, SL, and SGV preoperative and >12 months postoperative. A 1-year postoperative patient satisfaction survey was conducted. Results: The platysmal hammock flap without midline platysmaplasty cohort had a significant (P < 0.01) reduction in mean preoperative PB, SL, and SGV scores from 1.03, 1.88, and 1.21 to 0.06, 0.03, and 0.15 at 21 months. The platysmal hammock flap with midline platysmaplasty cohort had a significant (P < 0.01) reduction in preoperative PB, SL, and SGV scores from 1.81, 2.43, and 1.81 to 0.10, 0.15, and 0.48 at 18 months. The platysmal hammock flap with and without midline platysmaplasty cohorts had 96.2% and 88.9% satisfaction, respectively. Conclusions: Extended deep-plane facelift with a platysmal hammock flap achieves long-term, sustained improvements in PB, SL, and SGV; is well-tolerated; and results in substantial patient satisfaction. Level of Evidence: 4.
