Unusual Presentation of Guillain-Barré Syndrome After Mandibular Fracture Treatment: A Review of the Literature and a New Case.

Guillain-Barré syndrome (GBS) is a multifactorial and lethal inflammatory demyelinating neuronal disorder with concurrent polyradiculopathy and polyneuropathy presentations. This rare syndrome affects the peripheral nerve myelin sheath and is characterized by ascending muscle weakness and paralysis. There have been rare reports of GBS after head or brachial plexus trauma, general anesthesia, neurosurgery, orthopedic surgery, cesarean section, laparoscopy, and general surgery, and the occurrence of GBS after oral and maxillofacial surgery is not common. A review of the related literature and a new case of GBS after maxillofacial surgery are presented.
