 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.

Absolute Phase

Electromyographical examination of 103 patients with Bells palsy in acute and recovering periods of disease has been carried out. A number of functioning motor units, silence period, sinergy coefficients in mimic muscles have been studied. A significant decrease of index of a number of functioning motor units, correlating to severity of facial nerve injury, decrease of the durability of absolute phase of silence period, disturbance of coordinational correlation of mimic muscles are revealed. Significance of revealing prolonged decrease of durability of absolute phase of silence period and increase of sinergy coefficients for prediction of possibility of development of secondary contracture of mimic muscles is presented.

To determine the variability of the abnormalities found in the electroneurography (ENG) of the facial nerve in cases of Bell's palsy during the initial two week period was one of the objectives of the authors. A second one was to investigate the value of ENG as a tool to determine an early prognosis of recovery utilizing two different methods. In the first one the amplitude of the compound muscular action potential (CMAP) obtained on the paralyzed side was compared to this potential on the opposite (normal) side. The second method compared the CMAP on the paralyzed side to normal standardized data from normal individuals. A group of 33 patients with Bell's palsy was followed until total recovery or for at least 4 months, if the recovery was not achieved earlier. It was observed that amplitude of the CMAP become stable towards the sixth day of palsy and this is a good time to establish the prognosis. Another conclusion is that both methods were equivalent to determine the prognosis in Bell's palsy.
