| Subcutaneous emphysema is most likely to occur in the postoperative period or if there is trauma to the trachea that occurs via suctioning. In addition, vigorous movement or mishandling the tracheostomy tube can create perforations and increase complications. Esophageal complications such as dysphagia can occur. Tracheoesophageal fistulas are not common but do occur. It is formed when the connective tissue between the esophagus and trachea grows together.
Ulceration and tissue damage may include the formation of a granuloma at the distal end of the cuff. The granuloma may obstruct the tube. A granuloma forms from inflamed tissue fusing together, or because the tracheostomy tube is sliding back and forth. | | | | |
