My son is a month old and he was born open delivery face up, the right side of his mouth is crooked when he cries, will this heal?

See an ENT: It sounds like this could be an issue of facial paralysis. This can come from a difficult delivery, or can be something the baby is born with. It would be a good idea to see a pediatric ENT (or a general ENT comfortable with neonatal facial paralysis as not all will be) for a check up. Often the nerve will start working again on its own but other times testing such as with an MRI may be needed.

Depends: The "asymmetric crying facies" differs from facial paralysis by lack of problems closing the eye on the affected side.It is caused by absence or underdevelopment of the depressor anguli muscle of the mouth on the affected side. It can be found alone or associated with other defects. When it shows up as an isolated problem, improvement depends on the degree of the defect.Most improve with age.
