Oral Extrusion of a Screw After Anterior Cervical Spine Plating: A Case Report.

Although anterior cervical discectomy and fusion (ACDF) is one of the most common surgical procedures performed for the treatment of cervical disease, it is associated with a variety of postoperative complications. Esophageal perforation is a rare but very serious post-ACDF complication, and cases in which screws extrude through the mouth are even rarer. Herein, we present the case of a 61-year-old woman who visited our emergency center with oral extrusion of a screw 6 months after undergoing ACDF. Although diagnostic imaging did not confirm esophageal perforation, the oral extrusion of the screw was clear evidence of the complication. To the best of our knowledge, this is the first reported case of oral screw extrusion without confirmed esophageal injury. This case suggests that screw migration and esophageal perforation can occur depending on the patient's underlying condition, and if the symptoms are mild, conservative treatment alone may be sufficient to treat the perforation.
