Model-based simulations of the insertion of tensor threads in patient-specific face: a proof of concept

Résumé

Facial paralysis is associated with the loss of motricity of facial muscles, inducing face sagging under the effect of gravity, with aesthetic and functional consequences. In order to compensate for the sagging, surgeons have proposed a clinical procedure consisting of inserting and anchoring biodegradable tensor threads under the skin of the face, in order to restore tension to the sagging areas. This study allowed the realization of a proof of concept of a software tool that uses simulations with a Finite Element (FE) biomechanical model of the face [1] in order for the surgeons to (1) predict the behavior of the face after addition of tensor threads and (2) visualize preoperatively in real-time the postoperative aesthetic appearance of the patient's face using reduced order models (ROM) [2]
