Zusammenfassung

Hintergrund: Es gibt kein deutschsprachiges validiertes Instrument, um aus Patientensicht die krankheitsspezifische Lebensqualität bei einer Fazialisparese zu beurteilen.

Methoden: Die beiden geeigneten englischsprachigen Fragebögen, die Facial Clinimetric Evalua­tion (FaCE) -Skala und der Facial Disability-Index (FDI) wurden entsprechend internationaler Richtlinien übersetzt und validiert. Die interne Konsistenz der beiden deutschen Versionen wurde untersucht. Die Ergebnisse des FaCE und FDI wurden mit Ergebnissen des SF-36, der House-Brackmann-Skala und des Stennert-Index korreliert.

Ergebnisse: 122 Patienten wurden eingeschlossen mit einer medianen Paresedauer von 4,7 Monaten. FaCE und FDI zeigten gute bis sehr gute psychometrische Eigenschaften mit Cronbachs Alpha Werten zwischen 0,667 und 0,907. Beide Fragebögen könnten verschiedene Schweregrade der Parese gut unterscheiden. Die höchste Korrelation zum SF-36 zeigte sich für soziale Funk­tionsfähigkeit.

Diskussion: Die deutschen Versionen des FDI und des FaCE sind psychometrisch valide und sollten zur Untersuchung der krankheitsspezifischen Lebensqualität der Patienten mit Fazialisparese vermehrt eingesetzt werden.

Abstract

Background: A validated instrument to measure patient-related outcome and quality of life in facial palsy is not available in German language.

Methods: 2 appropriate questionnaires, the Facial Clinimetric Evaluation (FaCE) scale and the Facial Disability Index (FDI) were translated and validated according to international guidelines. The internal consistency of both German versions was assessed. The results of FaCE and FDI were correlated with results of the SF-36, the House-Brackmann scale and the Stennert index.

Results: 122 facial palsy patients with a median duration of 4.7 months were included. FaCE and FDI showed good to very good psychometric characteristics with Cronbach’s alpha values between 0.667 and 0.907. Both questionnaires were able to distinguish different degrees of facial palsy. The comparison to the SF-36 shows the highest correlation with the subscale social function.

Discussion: The German versions of the FDI and FaCE are valid and should now be applied more frequently to assess the disease-specific quality of life in patients with facial palsy.
