Neurological disorders and conditions affecting the maxillofacial region result in disabilities that affect an individual's functioning. Sensory or motor disturbances of the nerves may be caused by trauma, infections, pressure effect or infi ltration by tumours or other health conditions. Two rare cases of nerve afflictions are described here with their typical clinical features. The first case had an involvement of maxillary, mandibular and ophthalmic divisions of the trigeminal nerve (sensory) due to herpes zoster infection in a very young patient and the second case had a unilateral isolated hypoglossal nerve palsy (motor) secondary to infiltration of the nerve by carcinoma of pyriform fossa.
