Abstract

OBJECTIVE: To develop and validate a patient-based instrument to measure both facial impairment and disability, the Facial Clinimetric Evaluation (FaCE) Scale. STUDY DESIGN: Prospective instrument validation. METHODS: Eighty-six patients with a documented history of facial paralysis completed a preliminary, 51-item instrument (alpha FaCE Scale), as well as the previously developed Facial Disability Index (FDI) and the Medical Outcomes Study Short Form 36 Item Questionnaire (SF-36). Two weeks after completing these instruments, 76 patients again completed the alpha FaCE Scale. Forty-one of the patients were also evaluated using the House-Brackmann Grading System (HBGS) and the Facial Grading System (FGS). RESULTS: Exploratory principal component factor analysis grouped 15 FaCE Scale items into 6 impairment and disability categories (domains), forming the beta FaCE Scale. Overall, the test-retest reliability of the FaCE Scale was high (Spearman's correlation coefficient (r) = 0.88, P
