Summary
Facial paralysis evaluation using the Yanagihara and House-Brackmann (H-B) methods shows varied correlation with patient self-assessments. This highlights individual differences in perceiving subjective symptoms of facial paralysis.
Area of Science:
- Neurology
- Ophthalmology
- Plastic Surgery
Background:
- Facial paralysis evaluation commonly uses the Yanagihara and House-Brackmann (H-B) methods in Japan.
- Patient self-perception of facial paralysis severity is crucial for comprehensive assessment.
Purpose of the Study:
- To investigate the correlation between objective facial paralysis evaluations (Yanagihara and H-B methods) and patient self-evaluations.
- To understand the variability in subjective symptom reporting among patients with facial paralysis.
Main Methods:
- One hundred thirty-one patients with facial paralysis were assessed using the Yanagihara and H-B methods.
- Patients also completed two self-evaluation methods: a 1-6 grade scale and a 0-100 severity scale.
- Correlation analysis was performed between objective scores and self-reported data.
Main Results:
- Correlation strength between objective scores and self-evaluations varied significantly among patients.
- Discrepancies were observed even in patients classified as 'completely paralyzed' or 'cured'.
- Notably, 20-30% of patients deemed 'cured' reported minor dyskinesia.
Conclusions:
- Objective facial paralysis grading scales may not fully capture the patient's subjective experience.
- Individual variability in symptom perception necessitates considering patient self-evaluation in treatment and follow-up.
- Further research is needed to reconcile objective findings with patient-reported outcomes in facial paralysis.
