A comparative study of age and degree of facial nerve recovery in patients with Bell's palsy.

The purpose of this study was to investigate if there is any relationship between the age of a patient and the degree of facial nerve recovery in patients with Bell's palsy. Between 1987 and 1995 250 patients with peripheral idiopathic facial nerve palsy were examined at the ENT Clinic of the University of Ioannina. In this group 134 were male and 116 were female. The patients' ages ranged from 4 to 80 years and had an average of 47.7 years. The average age of the male patients was 46.5 years and that of the female patients was 49.1 years. In the overall group of 250 patients 129 presented with a paralysis of the right facial nerve and 121 on the left. There was no case of bilateral palsies. When comparing the age of the patients and the degree of recovery, measuring age was associated with a decrease in complete recovery. While the percentage of complete recovery between age 4 and 50 years varied from 83% to 74%, respectively, the percentage of complete recovery decreased to less than 54% at age 80. Our results show that the age of the patient is a very important factor for facial nerve recovery.
