ntroduction Nowadays, aesthetic surgery is facing new topics: the worldwide aging of the population, the rising request for looking younger, and the progressive request for less-invasive procedures (1,2). In particular, an increased demand for the treatment of skin aging of the neck has been observed in the last few years. The knowledge of factors contributing to the loss of shape and contour of the neck represents the basis for a targeted treatment. Neck muscles control extension, flexion, and lateral movements of the head and neck and contract several times during the day in order to adjust the posture, thus contributing to skin laxity (3). In addition, increased fat deposition, bone resorption, and submandibular gland protrusion can induce further variations (4). Submental fat accumulation contributes to an obtuse cervicomental angle and can age a patient or make him/her appear overweight. Variations involving the mandibular contour contribute to the aging of both the lower third of the face and the neck (4). The redefinition of the mandibular contour, through the liftup of the jawline and improvement of the neck appearance, could be previously performed only surgically (5,6). After that, several experiences with threads have been reported (7,8). In 2011, poly-L-Lactic acid (PLLA) traction threads were introduced onto the market. Literature regarding this kind of thread is lacking. The aim of our study is to describe a new technique to improve mandibular contour and to identify ideal candidates for this treatment, providing data concerning the efficacy and safety of the technique.
