Background:
The number of esophageal and pharyngeal perforations occurring in anterior cervical surgeries ranges from 0.25% to 1% and 0.2% to 1.2%, respectively. Symptoms usually appear postoperatively and are attributed to: Local infection, fistula, sepsis, or mediastinitis. Acute postoperative hematoma, although very rare (<1%), is the first complication to rule out due to its life-threatening complications (e.g. acute respiratory failure).
Case description:
Over a 36-year period, the author(s) described three severe esophageal/pharyngeal complications attributed to anterior cervical surgery. As these complications were appropriately recognized/treated, patients had favorable outcomes.
Conclusions:
Anterior cervical spine surgery is a safe approach and is associated with few major esophageal/pharyngeal complications, which most commonly include transient dysphagia and dysphonia. If symptoms persist, patients should be assessed for esophageal/pharyngeal defects utilizing appropriate imaging studies. Notably, even if the major complications listed above are adequately treated, optimal results are in no way guaranteed.
