Unmasking Oral and Facial Clues in Guillain–Barré Syndrome

Guillain–Barré syndrome (GBS) is an immune-mediated neuropathy often triggered by infections, trauma, or vaccinations, leading to progressive neuromuscular weakness. It involves autoimmune damage to peripheral nerves. GBS presents with motor deficits, paraesthesia, pain, cranial nerve involvement, especially the facial nerve. Although its acute neurological features are well-recognized, the oral manifestations – such as dysphonia, dysphagia, masticatory dysfunction, and taste disturbances – are underreported. Awareness of these signs is essential for dentists to aid early diagnosis and multidisciplinary management.
