Marin-Amat syndrome is a rare form of facial synkinesis resulting from aberrant connections between thetrigeminal and facial nerves. This condition manifests as involuntary eyelid closure upon voluntary jawmovement. It is distinct from the more common Marcus Gunn jaw-winking syndrome (MGJWS), whichinvolves upper eyelid elevation during mastication. Here, we reported a case of a 64-year-old woman whodeveloped this syndrome following combat-related maxillofacial trauma to the lateral mandible, which resultedin a left facial nerve injury. After her mandibular fractures were stabilized using 2 mm plates, her medicalhistory was notable only for hypothyroidism. Six months post-injury, and following an attempted free fibula flapprocedure, the patient began experiencing involuntary facial movements. These symptoms caused significantsocial discomfort and difficulty with eating. Treatment options, including botulinum toxin and surgery, werediscussed; however, the patient opted for a conservative management approach.
