| Popis: | OBJECTIVE We examined the relationship between the time course of development of facial synkinesis in patients with Bell's palsy and the severity of facial nerve damage. STUDY DESIGN Retrospective study. SETTING Tertiary referral center. PATIENTS Thirty-nine consecutive patients with Bell's palsy who developed synkinesis. INTERVENTION Diagnostic. MAIN OUTCOME MEASURES Subjects were divided into groups A (electroneurographic [ENoG] value, or =10%; n = 8). Development of facial synkinesis was assessed based on the appearance of synkinetic potentials from the orbicularis oris muscle on the blink reflex test. Times to appearance of facial synkinesis in groups A and B were compared. The proportion of patients who developed facial synkinesis after complete recovery of facial movement was also assessed in 14 patients whose facial movement recovered completely. RESULTS The mean time to maximal recovery of facial movement was significantly longer in group A than in group B (p < 0.001), whereas the duration between the appearance of facial synkinesis and the onset of facial paralysis did not differ significantly between the 2 groups (p = 0.72). The proportion of patients who developed facial synkinesis after complete recovery of facial movement was significantly greater in group B than in group A (p = 0.015). CONCLUSION During the course of recovery from Bell's palsy, the patients with an ENoG value of 10% or greater have a higher risk of developing facial synkinesis after complete recovery of facial movement. |
