In the entity of the peripheral facial palsies, there are idiopathic, otitic, traumatic palsy, Ramsay Hunt's syndrome, and others. The causes of the facial palsies were due to the disturbance of microcirculation and the bleeding in Fallopian canal, infection of bacteria and virus, the direct damage of the facial nerve and etc..
Some of them occur accompanying with the systemic disease. We reported 8 cases of the facial palsies which were accompanied with the systemic disease. These systemic disease were diabetes mellitus, sarcoidosis, aseptic and carcinomatous meningitis, systemic lupus erythematosus, aplastic anemia, and pregnancy. The facial palsies accompanied with diabetes mellitus and pregnancy are due to the disturbance of microcirculation (anoxia, ischemia, microembolism). As sarcoidosis sometimes involves in degeneration of myelin, and aseptic meningitis and infectious mononucleosis are viral infection of seventh nerve, these cause probably a neuritis or a ganglionitis. The palsy of carcinomatous meningitis is rare, but if initial symptom is only facial palsy, this palsy should be differentiated from idiopathic facial palsy (Bell's palsy).
As aplastic anemia causes the tendency of bleeding, this palsy occurs from the bleeding in Fallopian canal. One case of the facial palsy accompanying the aplasic anemia revealed the bleeding in Fallopian canal by autopsy. The importance of systemic disease as a possible cause of idiopathic facial palsy was emphasized.
