About this study
The facial palsy concerns between 15 and 40 people per 100000 inhabitants. They are of various etiologies such as infectious, tumoral, traumatic or idiopathic.
It has variable severities with sometimes heavy functional repercussions and different recovery potentials. The proposed palliative treatments are based on surgery, physiotherapy and botulinum toxin injections. However, when recovery is incomplete, acceptance is more difficult, with an impacted quality of life. In this context, patients' expectations and feelings about their care may become difficult for clinicians to apprehend.
The eye-tracking is widely used in the marketing field, but it also finds medical applications including head and neck lesions and facial palsy in particular. Published studies focus on the gaze of photographs, excluding any notion of dynamics and by the analysis of the gaze of outside observers, ignoring the patient's gaze.The main objective is to evaluate the attention paid to the facial side with abnormal facial movement by patients with facial paralysis compared to healthy volunteers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Video sequencesOther
videos will be made of each participant, during the realization of 5 movements that are the simple closure of the eyelids, the forced closure of the eyelids, the labial protrusion on the sound [o], the labial protrusion on the sound [pu] and the wide smile uncovering the teeth.
Then, a video sequence will be realized thanks to the dedicated software Tobii Pro Lab®.

|---|---|---|
| facial palsy | Experimental | Patient with peripheral facial palsy, irrespective of grade, whether or not previously treated Receives: Other: Video sequences |
| healthy volunteers | Sham comparator | - Subject without major facial sequelae Receives: Other: Video sequences |
What is being measured
The primary outcome is the main question the study is designed to answer.
Variation of facial fixation day number between facial palsy patients and healthy volunteers
