Anterior retropharyngeal approach (ARPA) for high cervical spine.

BACKGROUND: One of the major challenges in operating on the spine lies in taking an anterior approach for the high cervical spine. In patients with a short neck, Klippel-Fiel syndrome or when the C3 vertebra is high in relation to the hyoid bone, it will be difficult to access the C3 body. The transoral route is a highly contaminated zone, and therefore, no instrumentation or grafts can be placed through it. METHOD: The anterior retropharyngeal approach (ARPA) for the high cervical spine. CONCLUSION: The anterior retropharyngeal approach is an excellent approach for the high cervical spine where instrumentation is needed. This route provides wide exposure of the C1-C3 region, avoiding the contaminated of the oral cavity.
