Bilateral Alternating Bell's Palsy Treated with Stellate Ganglion Block -A case report-

양측 교대형 안면신경 마비의 치험 -증례 보고-

Facial nerve paralysis is a common pain clinical diagnosis. But ipsilateral or contralateral recurrent facial paralysis is found in about 2.6~19.5% of facial paralysis and especially bilateral facial paralysis is rare. While idiopathic facial paralysis is the most common diagnosis, a comprehensive evaluation must be completed prior to this diagnosis in patients with bilateral facial paralysis. A representative case of bilateral alternating facial paralysis treated with stellate ganglion block (SGB) is presented. A 57 years old male patient who had the onset of a right facial paralysis 7 months ago visited pain clinic. Five months after the onset of right facial paralysis, as it was improving, he developed a left facial paralysis. He had history of hypertension, diabetus mellitus and pain episode on mastoid process before facial paralysis developed. Electrical test showed incomplete neuropathy on both side and computed tomography (CT) scan was normal. He was treated with SGB, physical theraphy and aspirin medication. After 25 times SGB, he was recovered almost completely.
