Abstract
Submandibular gland function was tested with 99mTc-pertechnetate scan 10 days and 3-4 weeks after the onset Bell's palsy, and the results and prognoses were correlated.
In the first report we divided the cases into groups A, B and C, and this time group D classified in S. S. R. was poor.
Groups A and D can be differentiated by submandibular gland scan within 10 days after the onset; that is to say, the prognosis of more than half the cases can be determined in this early phase.
Especially, it is noticeable that group D showing the poor prognosis is differentiated within 10 days after the onset.
This method was compared with other tests of facial palsy.
Four to five weeks after the onset all tests were of equal accuracy in predicting the prognosis of each group.
Within 10 days after the onset, however, submandibular gland scan seems to be more useful than the other tests.
