## Overview Lip motor dysfunction is loss of fine control of the lips, usually from facial nerve damage. The horse cannot sort feed or grasp small particles well, eats messily, and may have hay hanging from the mouth. The upper lip may appear stiff or immobile. ## Causes Facial nerve paralysis from trauma, pressure, or central lesions. ## Diagnosis Observation of eating and neurologic examination of facial movement. ## Treatment Treat the underlying nerve injury. Supportive feeding with easily grasped feeds. Many peripheral nerve injuries improve over time. ## Recovery and Prognosis Variable. Mild cases often regain useful function. Severe or central lesions may leave permanent deficits. ## Prevention Avoidance of facial trauma and careful halter use.
