Does the Approach of the Lateral Platysmal Bands Widen the Gap between the Medial Bands?

Abstract

Background: The first visible change in an aging face and neck is the loss of neck contour, which can be corrected by treating the platysmal bands; however, it remains unclear as to which is the best strategy to approach these bands. The aim of the present study is to verify whether the lateral platysmal bands approaches, before the medial ones, cause widening of the gap between them. Methods: This is a prospective, randomized, comparative study involving 30 individuals presenting various stages of neck and facial flaccidity and sagging. The patients were split into 2 groups according to the lateral platysmal approach (group A: lateral platysmal traction/plication; group B: lateral platysmal undermined/traction). A protocol was established to measure the gap between the medial bands, 3 and 5 cm away from the chin, before and after superficial musculoaponeurotic system/platysma lateral suspension. Measurements were taken using a compass and a ruler. The endpoint was to determine whether the gap between the medial platysmal bands widens after the lateral procedure. Results: Group A, first measure (1-M): the gap ranged between 1.0 and 1.6 cm in point M3 (3 cm away from chin) and between 1.8 and 3.0 cm in point M5 (5 cm away from chin) (mean in M3 = 1.2; SD, 0.22 and mean in M5 =2.3; SD, 0.52). Group A, second measure (2-M): the measure ranged between 1.0 and 1.7 cm in point M3 and between 1.8 and 3.2 cm in point M5 (mean = 1.28; SD, 0.25 and mean = 2.42; SD, 0.63, respectively). Group B, first measure (1-M): the gap ranged between 1.1 and 1.7 cm in M3 (mean = 1.32; SD, 0.21) and between 1.8 and 3.2 cm in M5 (mean = 2.38; SD, 0.57). Group B, second measure (2-M): the measure ranged between 1.2 and 1.7 cm in M3 (mean = 1.4; SD, 0.18) and between 2.0 and 3.2 cm in M5 (mean = 2.5; SD, 0.55). Group A: P = 0.07 (M3) and 0.10 (M5); Group B: P = 0.09 (M3) and 0.07 (M5). Conclusion: The lateral platysmal approach, plication or undermined, does not lead to a widening of the gap between the medial platysmal bands.

“…In a study conducted by L. Charles-de-Sá et al, the authors aimed to determine whether the traction of the lateral platysma could potentially increase the distance between the medial platysmal bands. However, their findings concluded that the lateral platysmal approach, whether through plication or dissection, does not lead to an expansion of the distance between the medial platysmal bands [31].…”
