Facial nerve palsy

Weakness of total paralysis of 1 or more branches of the facial nerve.

This problem can be encountered as part of craniofacial microsomia or for instance as part of Moebius syndrome.

The presentation can be very mild, with only weakness of the mandibular branch, resulting in a slightly asymmetric mouth when crying, or full blown with complete absence of motor function of the nerve. This can result in a low position of the eyebrow with inability to raise it, inability to close the eyelids, drooling due to lack of muscular functioning of the mouth.

Several surgical options are available, all depending on the severity of the condition.
