Résumé
Most used subjective Unilateral Peripheral Facial Palsy (UPFP) grading systems are characterized by high variability and low reproducibility and doesn't allow a separate evaluation of single facial regions. To assess the reliability of a new objective method for classification of UPFP, comparing it with House-Brackmann (HB) and Sunnybrook facial grading (SFGS) systems. Forty-seven patients affected by UPFP of different HB grade were included. Each patient underwent a blinded examination by three different operators, via the two subjective methods (HBGS and SFGS) and a newly proposed objective one, that was obtained from a digital video-analysis, named SMART FACIAL system. Results were converted by validated conversion scales into HBGS grades and statistically compared. In 87,23% (n° 41 pts) consistency was found between the grades obtained with all the three evaluation methods; in 10,41% (n°5 pts), between HBGS and SFGS grade and in 2,08% (n°1 pt) between HBGS grades and SMART-FACIAL system. Statistical analysis showed significant correlation among the three systems (p < .000). The SMART FACIAL system presents high reliability also in comparison with the most frequently used subjective methods. This method represents a fast, simple and thorough way to analyze UPFP, especially during physical rehabilitation.

BACKGROUND
BACKGROUND
Most used subjective Unilateral Peripheral Facial Palsy (UPFP) grading systems are characterized by high variability and low reproducibility and doesn't allow a separate evaluation of single facial regions.
OBJECTIVE
OBJECTIVE
To assess the reliability of a new objective method for classification of UPFP, comparing it with House-Brackmann (HB) and Sunnybrook facial grading (SFGS) systems.
METHOD
METHODS
Forty-seven patients affected by UPFP of different HB grade were included. Each patient underwent a blinded examination by three different operators, via the two subjective methods (HBGS and SFGS) and a newly proposed objective one, that was obtained from a digital video-analysis, named SMART FACIAL system. Results were converted by validated conversion scales into HBGS grades and statistically compared.
RESULTS
RESULTS
In 87,23% (n° 41 pts) consistency was found between the grades obtained with all the three evaluation methods; in 10,41% (n°5 pts), between HBGS and SFGS grade and in 2,08% (n°1 pt) between HBGS grades and SMART-FACIAL system. Statistical analysis showed significant correlation among the three systems (p < .000).
CONCLUSIONS
CONCLUSIONS
The SMART FACIAL system presents high reliability also in comparison with the most frequently used subjective methods.
SIGNIFICANCE
CONCLUSIONS
This method represents a fast, simple and thorough way to analyze UPFP, especially during physical rehabilitation.
