ACQUIRED PHARYNGEAL DIVERTICULUM FOLLOWING ANTERIOR CERVICAL FUSION OPERATION

SUMMARY We report an unusual case of a pharyngeal diverticulum arising as a result of extrusion of a bone graft inserted during anterior cervical fusion operation. The dense scar tissue at the site of extrusion of the bone graft probably caused traction on the posterior pharyngeal wall, with the development of a pharyngeal pouch. This is believed to be the first case with acquired pharyngeal diverticulum following anterior cervical fusion to be recorded in the literature.
