Cervico-Mental Angle Suspensory Ligament: The Keystone to Understand the Cervico-Mental Angle and the Ageing Process of the Neck

The authors performed cadaveric dissections to investigate the existence of an anatomical structure creating and maintaining the cervical mental angle, aiming to understand the anatomical bases of the cervico-mental angle and its modifications over time. Six fresh cadaver dissections were performed; four were done in the Caen University anatomy laboratory one in Paris XV University and one in the Coventry University hospital, England. At the end of this investigation, the authors were able to demonstrate the existence of an anatomical structure in the neck, the cervico-mental angle suspensory ligament. This ligament that fixates the platysma and skin to deeper structures originated from the second branchial arch and seems to play a key role in the formation of the cervico-mental angle and in the anatomical alterations in the ageing process.
