 Background: Nerve conduction study (NCS) is an important electrophysiological tool that can be used for the measurement of the latency and amplitude of the facial nerve. The NCS helps in predicting the prognosis of patients with Bell's palsy. Evaluation of NCS of patients with Bell's palsy may have contribution in counselling and management of the patient. Objective: The study was aimed to study the state of nerve damage in patients with Bell's palsy. Methods: The latency and amplitude of facial nerve stimulating bilateral Orbicularis Oculi and Orbicularis Oris muscles were assessed and noted in 24 patients of Bell's palsy. Results: 15(62.5%) of the patients had significant axonal injury affecting one side and only 1(4.16%) patient had demyelinating injury. The total of 8(33.33%) patients had insignificant axonal injury of the facial nerve in comparision with the normal side. Conclusions: Nerve conduction study shows predominant axonal type of facial nerve injury in patients with Bell's palsy and hence provides valuable information regarding the prognosis and the state of nerve damage in patients with Bell's palsy.

A group of patients with Bell's palsy were studied in order to disclose the presence of subclinical peripheral nerve involvement. 20 patients, 8 male and 12 female, with recent Bell's palsy as their unique disease were examined, in all cases other causes of polyneuropathy were ruled out. Patients were investigated with CSF examination, facial nerve latencies in the affected and in the sound sides, and maximal motor nerve conduction velocities, as well as motor terminal latencies from the right median and peroneal nerves. CSF laboratory examination was normal in all cases. Facial nerve latencies were abnormal in all patients in the affected side, and they differed significantly from those of control group in the clinically sound side. Half of the patients showed abnormal values in the maximal motor nerve conduction velocities and motor terminal latencies of the right median and peroneal nerves. These results agree with previous reports which have pointed out that other cranial nerves may be affected in Bell's palsy. However, we have found a higher frequency of peripheral nerve involvement in this entity. These findings, support the hypothesis that in some patients Bell's palsy is the component of a more widespread disease, affecting other cranial and peripheral nerves.

Nerve Conduction Block

There is controversy on the management of the idiopathic facial nerve palsies (Bell’s palsy). About two out of every three patients have a nerve conduction block alone and recover completely in less than one month.1 The rest develop denervation of the facial muscles to a varying degree and never recover completely. In addition, contracture of the facial muscles may occur, with severe disfigurement. About 10% of all patients with facial palsy have complete denervation and serious sequelae.2 Using electromyography3 and measurement of the anodal galvanic threshold4 an accurate prognosis can be given within the first week.

AbstractIncomplete recovery from Bell's palsy was observed in some patients even after the intake of corticosteroids. This prospective study was performed on 160 patients with unilaterial nonrecurrent Bell's palsy in order to investigate the role of prednisolone on the prognosis of Bell's palsy. Ninety-three patients were given prednisolone tablets (1 mg/kg body wt/day up to 70 mg) for six successive days, then the dose was reduced gradually over the next four days. The remaining 67 patients were not given prednisolone (control group). Facial nerve recovery was assessed clinically and electrophysiologically for up to one year. The results of this study suggested that the most probable contributing factor for the success of prednisolone in improving the prognosis of Bell's palsy was its early intake (within the first 24 hours following onset).
