Case of essential palatal tremor: atypical features and remarkable benefit from botulinum toxin injection

Mov Disord. 2001 Jul;16(4):779-82. doi: 10.1002/mds.1132.


We describe a 21-year-old man with essential palatal tremor. The patient had rhythmic contractions not only of tensor veli palatini but also of facial, lingual, temporalis, pharyngeal, and neck muscles. He had some voluntary control of palatal tremor and ear clicks. He was treated with 5 units of botulinum toxin-A (BOTOX) injected into each tensor veli palatini, and had complete resolution of all the symptoms.
