title: Another Scale for the Assessment of Facial Paralysis? ADS Scale: Our Proposition, How to Use It.
abstract: BACKGROUND
  Several authors in the years propose different methods to evaluate areas and specific movement's disease in patient affected by facial palsy. Despite these efforts the House Brackmann is anyway the most used assessment in medical community.
  
  
  OBJECTIVE
  The aims of our study is the proposition and assessing a new rating Arianna Disease Scale (ADS) for the clinical evaluation of facial paralysis.
  
  
  METHODS
  Sixty patients affected by unilateral facial Bell paralysis were enrolled in a prospective study from 2012 to 2014. Their facial nerve function was evaluated with our assessment analysing facial district divided in upper, middle and lower third. We analysed different facial expressions. Each movement corresponded to the action of different muscles. The action of each muscle was scored from 0 to 1, with 0 corresponding from complete flaccid paralysis to muscle's normal function ending with a score of 1. Synkinesis was considered and evaluated also in the scale with a fixed 0.5 score. Our results considered ease and speed of evaluation of the assessment, the accuracy of muscle deficit and the ability to calculate synkinesis using a score.
  
  
  RESULTS
  All the three observers agreed 100% in the highest degree of deficit. We found some discrepancies in intermediate score with 92% agreement in upper face, 87% in middle and 80% in lower face, where there were more muscles involved in movements.
  
  
  CONCLUSIONS
  Our scale had some limitations linked to the small group of patients evaluated and we had a little difficulty understanding the intermediate score of 0.3 and 0.7. However, this was an accurate tool to quickly evaluate facial nerve function. This has potential as an alternative scale to and to diagnose facial nerve disorders.
