Purpose The clinician-graded electronic facial paralysis assessment (eFACE) is a relatively new digital tool for assessing
facial palsy. The present study aimed to determine the validity and reliability of the Spanish version of the eFACE.
Methods Forward–backward translation from the original English version was performed. Videos and photographs from 65
adult patients with unilateral facial paralysis (any severity, time course, and etiology) were evaluated twice by fve otolaryngologists with varying levels of experience in facial palsy evaluation. Internal consistency was measured using Cronbach’s
α and the intra- and inter-rater reliability were measured using intraclass correlation coefcient. Concurrent validity was
established by calculating Spearman’s rho correlation (ρ) between the eFACE and the House–Brackmann scale (H–B) and
Pearson’s correlation (r) between the eFACE and the Sunnybrook Facial Grading System (SFGS).
Results The Spanish version of the eFACE showed good internal consistency (Cronbach’s α>0.8). The intra-rater reliability
was nearly perfect for the total score (intraclass correlation coefcient: 0.95–0.99), static score (0.92–0.96), and dynamic
score (0.96–0.99) and important-to-excellent for synkinesis score (0.79–0.96). The inter-rater reliability was excellent for
the total score (0.85–0.93), static score (0.80–0.90), and dynamic score (0.90–0.95) and moderate-to-important for the synkinesis score (0.55–0.78). The eFACE had a very strong correlation with the H–B (ρ= – 0.88 and – 0.85 for each evaluation,
p<0.001) and the SFGS (r=0.92 and 0.91 each evaluation, p<0.001).
Conclusion The Spanish version of the eFACE is a reliable and valid instrument for assessment of facial function in the
diagnosis and treatment of patients with facial paralysis
