The Background and Purpose : Most diagnostic method for the facial palsy were invasive and complex. And we don`t know very well prognosis for the recovery of facial palsy in the first stage after the onset. But the Digital Infrared Thermal Image(DITI) isn`t invasive and complex diagnostic method for the facial palsy. So we should study on the clinical prognostic diagnosis of Bell`s palsy among facial palsy with the DITI. Objective and Methods : This study researched into the clinical statistics for 89 case who are in Bell`s palsy, and they are treated with oriental medical care at the Woosuk university during 2 years form November 1998 to October 2000. All objectives have the Grade 6(Zero state) of Bell`s palsy in first week after the onset. It takes a patient`s facial temperature after the onset. Group A is taken from 1 day to 4 days after the onset. Group B is taken from 5 day to 8 days after the onset. And group C is taken from 9 day to 12 days after the onset. Results and Conclusions : The Digital Infrared thermal image technique showed the more high temperature, the more rapid cure and short treatment period on TE23, B2, S3, S6 in abnormal site of Bell`s palsy. But it showed the more low temperature, the more rapid cure and short treatment period on TE17 of abnormal site of Bell`s palsy. As a conclusion, we could think that the prognostic diagnosis of Bell`s palsy closely related with the thermal difference normal and abnormal site of Bell`s palsy that were took picture after the onset.
