“…(2) The ratio of patients older than 70 years old to the total number of patients is smaller than those of the Japanese population. (3) The ratio of patients aged from 20 to 69 years to the total number of patients is larger than those of the Japanese population (4). Between the ages of 30 and 49 years, men are more frequently affected with Bell's palsy than women (30 to 39, < .01; and 40 to 49, < .05).…”

\s=b\Bell's palsy was classified into five categories\p=m-\unilateralnonrecurrent, unilateral recurrent, simultaneous bilateral, alternating bilateral, and recurrent bilateral type-based on the clinical statistical study of two large series of patients with Bell's palsy treated at different locations in Japan. One series consisted of 1,217 patients and the other of 1,197 for a total of 2,414 patients in this study. The incidence of each type and the age and sex distributions were similar in the two groups. Clinical features of each type are described. The results imply that more specific causative factors trigger the recurrences and the simultaneous bilateral attacks. (Arch Otolaryngol 1984;110:374-377) Bell's palsy is an acute peripheral mononeuropathy of the seventh cranial nerve. Although recent re¬ search data suggest that either a viral infection or a circulatory disturbance may probably cause the disease, the actual cause of Bell's palsy remains speculative in clinical practice. The diagnosis of Bell's palsy is made only when all possible causes of facial pal¬ sy are excluded. Careful examination of the ear, nose, and throat and crani¬ al nerve functions is important to confirm that there is no abnormality in the ear or the neighboring struc¬ tures. In addition, conventional audiometric tests and roentgenograms of the temporal bone must be performed to rule out probable local causes of facial palsy. The systemic causes, namely, sarcoidosis, diabetes mellitus,

“…Central facial paralysis is classified into supranuclear paralysis and nuclear paralysis. Cases of central facial paralysis, even when the two types are combined, account for only 1% to 2% of all cases of facial paralysis 1–3 . Supranuclear facial paralysis should be subdivided into the cortical and subcortical types.…”

Central facial paralysis is classified into supranuclear paralysis and nuclear paralysis. Cases of central facial paralysis, even when the two types are combined, account for only 1% to 2% of all cases of facial paralysis) -3 Supranuclear facial paralysis should be subdivided into the cortical and subcortical types. The cortical center, which directly controls voluntary movements of the facial muscles, occupies one third of the fourth Brodmann area near the base of the skull in the anterior central gyrus of the frontal lobe and is called the face region. Damage in the face region in the anterior central gyrus causes cortical facial paralysis. Symptoms are often less severe in cortical facial paralysis than they are in peripheral facial paralysis. Because the anterior central gyms is near the inferior frontal gyms, which is the motor speech area, facial paralysis is often complicated by aphasia. Therefore, cortical facial paralysis is rarely considered to be an important issue in the clinical setting.It is generally accepted that in supranuclear facial paralysis, no paralysis is observed in the frontal muscle or the orbicular muscle of the eye. 4-7 To study cortical facial paralysis objectively, we investigated neurologic findings and facial paralysis scores using electromyography in patients with cortical facial paralysis caused by cerebral infarction without hemiplegia. CASE REPORTSCase I. A 33-year-old man with no remarkable personal or family history became inebriated and came home on September 26, 1992. The next morning he did not wake up, and his family simply thought he had a hangover. On the morning of September 28, he tried to call his company to report his absence but could not speak. He was referred to the neurosurgical department of our hospital by a local hospital, and he was admitted. On December 6, he consulted our department for speech therapy. Very slight right facial paralysis was observed. He was aware of discomfort in the right side of his face when he smiled or moved his lips while eating, No
