Abstract
Congenital facial nerve palsy (CFNP) is a rare condition that can be generally categorized as developmental or traumatic. Though trauma during birth is the most common cause, sometimes CFNP is observed in association with genetic syndromes and congenital hearing loss and structural anomalies of the middle and inner ear. CFNP is infrequently reported in association with branchio–oto–renal (BOR) syndrome. We present a case of a 4-day-old infant girl with a familial history of renal disease, who was hospitalized because of congenital unilateral facial palsy, which subsequently appeared to be a part of BOR syndrome and led to the diagnosis of congenital bilateral renal hypoplasia, renal failure, and secondary arterial hypertension. This case proves that sometimes rare manifestations of BOR syndrome may be one of the first signs of an underlying syndrome. Issues regarding patterns of BOR syndrome inheritability and expressivity that we encountered are also discussed. Patients with a familial history of BOR syndrome should be carefully inspected after birth, especially in suspected cases such as newborns with preauricular pits and/or facial nerve palsy.
