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 approximately 0.2% of live births.
Causes include:
- perinatal trauma
- intrauterine posture
- intrapartum compression
- familial and congenital aplasia of the facial nerve nucleus
- cardiofacial syndrome
- Mobius syndrome (bilateral)
- Poland syndrome (only occasionally associated with CFP)
- Goldenhaar syndrome (only occasionally associated with CFP)
