Oral PathologyCervical sympathetic paralysis (Horners syndrome) causes anhidrosis of the homolateral (same) side of the face due to loss of sympathetic innervation to sweat glands. This results in decreased sweating on the affected side. Facial nerve trauma affects motor function, trigeminal nerve trauma affects sensation, and cerebral embolus affects central function, but none specifically cause unilateral facial anhidrosis.
