In the present study, this analysis included the time needed for the facial nerve suprastapedial lesion to transform to infrastapedial lesion, as assessed by the acoustic reflex determination, and the time needed for the HB scale score to reach 1, indicating recovery in the groups of patients diagnosed with borreliosis, Bell's palsy and HSV-1 infection.
The percentage of patients with suprastapedial lesion declined continuously with time in all three diagnostic groups.
In this group of patients, approximately half of the patients (53%) achieved recovery by week 6, as compared with the majority of Bell's palsy patients (79%) having recovered by week 3 and the majority of HSV-1 patients (71%) being free from suprastapedial lesion on initial measurement (Table 1).
