Case in brief
Two patients with essential palatal myoclonus (PM) underwent photobiomodulation therapy (PBMT) after conventional treatments failed. The first patient, a 26-year-old female, experienced a significant reduction in contraction frequency from 2.5 Hz to 0.11 Hz over 20 sessions, with sustained improvement in swallowing and sleep over 7 years. The second patient, a 28-year-old male, showed a decrease from 3 Hz to 0.3 Hz within 60 days, with notable functional improvement.
Diagnostic / clinical pearl
Photobiomodulation therapy may provide a noninvasive and effective treatment option for essential palatal myoclonus, particularly in cases unresponsive to conventional therapies.
