RESUMEN
This study was done in El-Zahraa University hospital. Thirty patients suffering from idiopathic Facial palsy [Bell's palsy] were included in this research. They were subjected to full history thorough clinical examination. The patients were divided into two groups. according to their final outcome, all patients were subjected also to electoromyography for motor unit action potential. The first group [19 patients] and the second group [11 patients], the time for recovery was significantly shorter in the first group [4.6 +/- 1.34] months compared with those for the second group [9.4 +/- 1.36] months. The patients were also divided into those who had more or less than 90% degeneration as determined by the electorneurography. All the patients but two of those whose degeneration less than 90% made a complete recovery while two of those with more than 90% made complete recovery. The final clinical outcome was also graded using the House and Brackman system. Eighty - nine per cent of those recovered completely has been predicted by ENoG within 10 days of onset
