The aim of the study was to determine the long-term recovery after Bell’s palsy and evaluate specific parameters and diagnostic procedures in predicting the long-term outcome of the disease. Forty-four patients, fifteen (15) men, twenty-one (21) women and eight (8) children, with idiopathic facial nerve paralysis were examined retrospectively and re-examined one to six years after the onset of the disease (average: 4.01 years). The failure rate of complete recovery was studied for each of these four factors: age, nerve excitability test (NET), initial severity of paralysis according to House-Brackmann scale grading and number of days from onset of paralysis to the beginning of medical treatment. For the twenty-two (22) patients, who underwent electroneurography at the onset of the disease, the correlation between the percentage of facial nerve fibre degeneration of the paralysed side and the long-term recovery was studied. From the 44 patients of our sample, 24 (54.5%) had House-Brackmann I, 8 patients (18.2%) had ΙΙ, 8 (18.2%) ΙΙΙ, three (6.8%) IV and a single patient (2.3%) V. According to our data, only the initial House-Brackmann grading of facial paralysis showed a statistically significant relationship with poor prognosis of the disease. Additionally, the percentage of facial nerve fibre degeneration of the paralysed side was found to have a statistical significant relationship with the long-term recovery after Bell’s palsy.
