Morphometric Study of the Muscles of the Skin in MRI 3 Tesla in Patients With Facial Paralysis.

The problem posed is the possibility of objectively assessing facial muscle mobility. Today, in patients with facial paralysis, the assessment of the deficit is carried out using a subjective scale such as the House Brackman \[1\] or EMG scale of the facial nerve but does not distinguish each muscle individually . Objective measurements of skin muscles such as thickness and volume, in preoperative assessment of a facial paralysis rehabilitation surgery, would be useful in order to choose the most appropriate surgical technique. Indeed, too much amyotrophy will contraindicate hypoglosso-facial anastomosis (VII-XII) and it will be preferable to propose a temporal elongation myoplasty or a reinfused free muscle flap. Similarly, it would be useful to be able to objectively evaluate the recovery of muscle function after facial allo-transplantation. Although electromyography has been develo
