Branchio-oculo-facial (BOF) syndrome is a rare autosomal dominant disorder
that has a distinct phenotype with characteristic craniofacial abnormalitie
s. These consist of branchial anomalies, including supra-auricular sinuses,
and aplastic cervical skin lesions, with possible ectopic dermal thymus, m
alformed auricles, stenotic external auditory canals, conductive hearing lo
ss, ocular abnormalities (microphthalmia and lacrimal duct obstruction), an
d pseudocleft of the upper lip. Extracraniofacial malformations are uncommo
n. We describe two new cases of BOF and discuss the classical clinical pres
entation and differential diagnosis. Our two patients presented with facial
nerve paralysis and were also were found to have inner ear dysplasias with
associated sensorineural hearing loss which, to our knowledge, have not be
en described in the literature in association with this syndrome. (C) 2000
