Sixth and Twelfth Cranial Nerve Palsies Following Basal Skull Fracture Involving Clivus and Occipital Condyle

摘要

Oblique basal skull fractures resulting from lateral crushing injuries involving both clivus and occipital condyle are rare due to their deep locations. Furthermore, these fractures may present clinically with multiple cranial nerve injuries because neural exit routes are restricted in this intricate region. The authors present an interesting case of basal skull fractures involving the clivus and occipital condyle and presenting with sixth and contralateral twelfth cranial nerve deficits. Clinico-anatomic correlations and the courses of cranial nerve deficits are reiterated. To the authors' knowledge, no other report has been previously issued on concomitant sixth and contralateral twelfth cranial nerve palsies following closed head injury.
