Guillain-Barre syndrome (GBS) is a postinfectious, autoimmune disorder which, 
apart from limb weakness, is characterised by cranial nerve involvement. 
Bilateral facial nerve palsy is the most common pattern of cranial nerve 
involvement in GBS. However, unilateral facial palsy, although uncommon, can be 
seen in GBS. We report a rare case of unilateral facial palsy in GBS and 
importance of electrophysiological tests including blink study in such cases has 
been emphasised.
