The function of the submandibular gland of 32 patients with Bell's palsy was examined with radio-isotope (RI) scincigraphy using 99mTc-pertechnetate; and the relationship between the function of the gland and the prognosis of palsy was discussed. Uptake and secretion of the RI in the glands on both sides were measured twice, the first time within 10 days of the onset of palsy, and the second time 3 to 4 weeks after the onset.The results were as follows: 1) In the case in which the function of the affected side was higher than that of normal side, the prognosis was good. 2) In the case in which the function of the affected side was lower than the normal in the first test but improved in the second test, the prognosis was also good. 3) In the case in which the function of the affected side was lower than the normal in the first test, and worsened in the second test, the prognosis was poor.In conclusion, the application of RI scincigraphy was thought to be very useful for early diagnosis of Bell's palsy.
