Resection of a Retropharyngeal Craniovertebral Junction Chordoma Through a Posterior Cervical Approach

Abstract

This illustrative case report is designed to provide technical data regarding the use of a posterior approach to resect a retropharyngeal chordoma involving the craniovertebral junction. The objective of this report is to emphasize the utility of the posterior approach when treating anterior tumors of the craniovertebral junction. Traditionally, a transoral transpharyngeal or extended anterior approach was used to resect anterior tumors of the craniovertebral junction. These approaches have several limitations unique to these exposures, limitations not applicable to a posterior midline cervical approach. A case report is provided that illustrates the use of a posterior cervical approach used to resect a retropharyngeal craniovertebral junction chordoma. Gross total resection of a retropharyngeal chordoma was achieved using a posterior cervical approach. Although local tumor recurrence did occur, this was resected and adjuvant radiotherapy prescribed. This resulted in an ongoing 4-year recurrence free survival. The posterior cervical midline exposure could be used to dissect and remove anterior retropharyngeal tumors, with minimal morbidity.
