Tracheotomy Dependence

Tracheotomy dependence is the state of having no choice but to breathe through a tracheotomy tube, because of an obstruction of the normal “pathway” for breathing into nose and/or mouth, through the larynx, and trachea to the lungs. Tracheotomy dependence may occur because part or all of the larynx has been removed, e.g., for cancer, or because of severe scarring or inflammation.

Granulation as a Cause of Tracheotomy Dependence

This unfortunate man suffered a severe auto accident, resulting in multi-system injuries, including a cervical spinal cord injury, closed head injury, and multiple fractures. He required an extended ICU stay on a ventilator via an endotracheal tube for his many surgical repairs, and while comatose.

After weeks of stabilization and recovery, he was transferred to a rehabilitation facility. Some weeks later, he developed progressive stridor, requiring an urgent tracheotomy. Though the trach-tube was subsequently removed, soon, increasing breathing difficulties necessitated its reinsertion. Due to his paralysis (para/quadriplegia), he continued to live in a longterm nursing facility. The tracheotomy remained for suctioning access and easier breathing.

He was able to occasionally plug the tube, using his voice by occluding the trach with a finger. However, 2 ½ years later, he completely lost the ability to speak and could no longer breathe through his nose or mouth when the trach tube was plugged.

Narrow Hypopharynx (1 of 4)

A distant view shows narrowing between the posterior pharyngeal wall (PPW) and the epiglottis (E), likely due to stabilizing hardware and new bone formation under his PPW, subsequent to his cervical spine fracture.

Endotracheal tube injury (2 of 4)

A somewhat dark view inside the laryngeal vestibule reveals evidence of an old endotracheal tube injury, with posterior cord erosions (arrow and dotted lines indicate expected cord position). Secretions pool in the distance, unable to drain past the trach tube or be cleared upward by coughing when plugging the trach.

Severe Granulation (3 of 4)

At first glance, the upper curvature of the trach tube appears to be completely obstructing the lumen, preventing the necessary “blow-by” airflow to power his voice. However, its darker coloration suggests it is not a standard white trach tube.

Avascular granuloma (4 of 4)

Closer inspection and patient attempts to speak (with momentary trach occlusion) reveal true cause—a large, ball valving, avascular granuloma. This mass had apparently gradually formed over time and had not spontaneously detached for over a year. Surgical removal will be necessary to restore adequate airflow (“blow-by”) and, with it, his ability to speak.
