However, its onset more than 1-year postoperatively is rare.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description:<\/jats:title>\n<jats:p>A 45-year-old male initially underwent a C3-4 and C5-6 anterior cervical discectomy and fusion (ACDF). At age 49, 4 years later, he presented with worsening dysphagia accompanied by neck and right upper extremity pain. Radiographs demonstrated an extruded left C3 screw, which had migrated into the prevertebral soft tissues at the C4-C5 level; there was also loosening of the right C3 screw. The subsequent barium swallow study revealed that the screw was embedded in the pharyngeal wall. The patient required a two-stage operation; first, to remove the anterior instrumentation, and second, to perform a posterior instrumented C2-T2 fusion.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion:<\/jats:title>\n<jats:p>A barium swallow study and other dynamic imaging are a valuable component of the diagnostic workup and therapeutic intervention to evaluate the delayed onset dysphagia following an ACDF.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_46_2020","type":"journal-article","created":{"date-parts":[[2020,2,28]],"date-time":"2020-02-28T08:52:10Z","timestamp":1582879930000},"page":"32","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The new onset of dysphagia four years after anterior cervical discectomy and fusion: Case report and literature review"],"prefix":"10.25259","volume":"11","author":[{"given":"Darius","family":"Ansari","sequence":"first","affiliation":[{"name":"Seattle Science Foundation, Seattle, Washington,"},{"name":"Department of Medicine, University of Illinois College of Medicine, Chicago, Illinois,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Halle E.
