Anatomical aspects and technical note of a modified retropharyngeal approach and reconstruction of the anterior occipitocervical junction.

Surgery to expose the anterior occiptocervical junction (OCJ) is exacting, and optimal approaches are debatable. The close proximity of vital structures and difficult surgical access present a unique challenge to treat lesions in this area. Routine access to the upper anterior cervical spine remains limited. The authors present a modified retropharyngeal approach and instrumentation in order to resect an exceptionally rare atypical rhabdoid teratoid tumor involving the craniovertebral junction. The technical aspects of this approach in anatomical perspectives are discussed in this article.
