Congenital facial palsy
A congenital facial palsy (CFP) is an uncommon cause of neonatal asymmetric crying facies, which are more frequently due to absence or hypoplasia of the depressor anguli oris muscle, often associated with other congenital anomalies.
CFP are reported with an incidence of ~0.2% of live births, making it a rare cause of facial palsy.
