Familial lower lip facial paralysis with asymmetric smile: Selective neurectomy of the cervical branch

Facial nerve paralysis in children is relatively rare and stems from a wide variety of entities. Congenital, acquired, iatrogenic, idiopathic etiologies all play a role, with Bell's palsy remaining the most common cause [1]. While there is significant literature on the most prevalent causes, familial facial nerve paralysis has only been sporadically described [1]. Prior studies have noted association with multiple facial nerve branches, specific alleles 3q21-22 and autosomal dominant transmission [2].
