Abstract
An injury to the pharynx and esophagus is a known complication of anterior cervical spine surgery. Two cases of delayed pharyngo-esophageal perforation following anterior cervical spine surgery that resulted in fistula are presented. We postulate that graft displacement and dislodgement of implant with resulting esophageal erosion was responsible for this complication.
