Résumé

La raison principale communément admise pour expliquer le vieillissement des structures du visage est l’effet de la gravité sur les tissus.

La théorie proposée ici est de donner à ce vieillissement comme cause principale et initiale les contractions répétées des muscles de la mimique. La gravité ayant, dans ce concept, un rôle secondaire sur le vieillissement initialement induit par les contractions musculaires.

L’étude IRM a récemment permis de démontrer la forme courbe à concavité postérieure des muscles de la mimique chez le sujet jeune. La cause de cette courbure est l’existence à la face postérieure de ces muscles d’un tissu graisseux profond ou corpus adiposum buccae décrit par Bichat.

L’explication physiologique de cette forme courbe des muscles de la mimique, dans le cadre de notre théorie, est la spécificité en direction et en amplitude que cette courbure confère aux mouvements musculaires propres à la mimique chez le sujet jeune.

Avec l’âge, progressivement, le muscle devient rectiligne et plus court à cause des contractions répétées qui chassent la graisse sous-jacente et augmentent le tonus de repos. L’expression du sujet s’en retrouve plus figée.

L’application de ces connaissances nouvelles au rajeunissement du visage donne naissance à de nouvelles possibilités techniques à la fois en médecine et en chirurgie esthétique.

Ces nouvelles techniques ont en commun leurs cibles : des segments de muscles de la mimique (maintenir dans le temps une bonne courbure musculaire et un tonus de repos bas) et les bombements graisseux sous-jacents.

Summary

Cutaneous ageing is responsible for the increasingly creased appearance of the skin, pores opening, skin dyschromia, while the ageing of the structures of the face is attributed primarily to the effect of gravity on the tissues.

The theory expounded below sets out to prove that the main and initial cause of this ageing is the repeated contractions of the mimic muscles. This concept attributes only a secondary role to gravity in the ageing process, which is initially brought about by muscular contractions.

An MRI study recently made it possible to demonstrate the anterior convexity curve of the mimic muscles in the young subject. This curve is due to the existence of a deep fat pad at the back of these muscles. While this mass of fat is effectively a mechanical sliding plane, its convexity constitutes the founding principle behind this new ageing theory.

In the young subject, the extent of its convexity and its location give a specific, youthful character to the movements, in terms of direction and amplitude , of the facial muscles. With age, the muscle gradually straightens and shortens, due to the repeated contractions that expel the underlying fat and increase the tonus at rest.

The structural ageing becomes visible and with time, the expression of the subject is consequently more rigid.
