Congenital facial palsy
A congenital facial palsy 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.
Congenital facial palsy is reported with an incidence of ~0.2% of live births, making it a rare cause of facial palsy.
