In the central and lateral parts of the neck, cords may appear over time, known as platysmal cords or dewlaps. They are due to the action of a skin muscle of the face and neck, the platysma muscle.
These unsightly bands age the neck and are a frequent request for consultation.
The platysma muscle pulls on the lower face and is one of the causes of sagging.
Over time, the two platysmal bands, the right and the left, separate and the muscle hypertrophies, leading to the appearance of platysmal cords.
There are different degrees of severity, represented by scales.
