Malformation of the external ear and facial paralysis caused by megatemperature hydro-aluminum

Abstract

We present a case of right lateral auricle contracture malformation, auricular canal atresia, and complete facial paralysis (House-Brackmann grade VI) caused by a megatemperature hydro-aluminum injury at work. The diastrophic auricle and auricular canal atresia were reshaped. The complete facial paralysis was reanimated to House-Brackmann grade III after surgical hypoglossal–facial end-to-end anastomosis. These outcomes indicate that hypoglossal–facial end-to-end anastomosis is an effective surgical option for successful reanimation of complete facial paralysis.
