Sixth cranial nerve palsy and ipsilateral segmental carotid arteritis after tooth alveolectomy
- 15 Downloads
Isolated sixth cranial nerve palsy caused by sphenoid sinusitis is a rare condition, especially if associated with segmental internal carotid arteritis (ICA). To our knowledge, there are 17 case reports describing sixth cranial nerve palsy secondary to sphenoid sinusitis and 18 case reports describing an isolated atypical arteritis of ICA. One of these reports presented novel “isolated internal carotid arteritis” disease concept which suggests arteritis caused by autoimmune disease of unknown cause is confirmed with the efficacy of steroid therapy and has no other symptoms or organ involvements, or autoantibodies (such as systemic lupus erythematosus and medium- or small-vessel vasculitis or Behçet’s disease) indicating autoimmune disease. Tuberculosis also has to be excluded, due to possible infectious vasculitis of sole ICA in tuberculous patient [1, 2, 3].
On the other hand, isolated sphenoid sinusitis (ISS) is a rare disease which accounts for 1% to 2% of all paranasal...
