Cranial Nerve |
Clinical Findings If Damaged |
IX (glossopharyngeal) |
loss of taste in the posterior third of the tongue |
X (vagus) |
paralysis of the palate and vocal cords |
XI (accessory, spinal) |
weakness of the trapezius and sternocleidomastoid muscles |
XII (hypoglossal) |
ipsilateral paralysis and atrophy of the tongue |
Additional findings:
(1) anesthesia of the palate, pharynx and larynx (due to involvement of CN IX and X)
Usually only one side is affected although bilateral involvement may occur. The weakness of the trapezius and sternocleidomastoid muscles should indicate the involved side. The tongue will deviate to the affected (paralyzed) side.
