Abstract
The author applied the two points discrimination test to the cases of bell's palsy for diagnosis of prognosis of the palsy using Uelenburg aesthesiometer and several reviews of anatomical and physiological aspects of facial region were performed. The normal values of DL for the two points sensation in facial region (trigeminal region) were 6 mm of medium, 0.4-0.7 mm of intra subject standard deviation and 1.1-1.7 mm of between subject standard deviation. Anatomical reviews revealed many anastomosis between facial nerve and trigeminal nerve. The results of this observation showed early recovery of DL for the two points sensation than recovery of mobility of face. The author hypothesized that recovery of DL for two points sensation in early stage of facial palsy is prognostic of the recovery of palsy.
