Abstract:
EMG-guided salpingopharyngeus Botox injection for palatal myoclonus. Palatal myoclonus (PM) is a rare neurological disorder characterized by involuntary movements of the soft palate musculature causing objective clicking tinnitus. Two forms are recognized as distinct clinical entities, with poorly understood pathogenesis: essential and symp- tomatic PM. The intrusive nature of the tinnitus prompts patients to seek medical advice. Conventional medical treat- ments with anxiolytics, antidepressants, and anticonvulsants have limited efficacy in these patients. In this case report, electromyography-guided injection of botulinum toxin type A (Botox; Allergan, Irvine, CA, USA) to the involved salpingopharyngeus and tensor veli palatini yielded satisfactory results with minimal temporary adverse effects.
