[Traumatic Tracheobronchial Injuries - Recommendation of the Interdisciplinary Working Group of the DGT and DGU to Establish a Uniform Classification for Diagnostics and Therapy].

Traumatic tracheobronchial injuries are extremely rare. In comparison, iatrogenic injuries are somewhat more common. A literature search revealed that there is a large number of case reports and small case series for this clinical entity. There are hardly any reviews and they usually have a low level of evidence. One reason for this is the lack of a classification to allow comparison of the individual cases with each other. There is only one classification for iatrogenic injuries of the posterior tracheal wall, which the authors modified and expanded with regard to traumatic tracheobronchial injuries. This classification was extended by the authors to also include traumatic injuries. A three-digit classification is presented here. The grading of the injury covers the entire spectrum of injury patterns, from peribronchial emphysema to wall injuries of different depths to subtotal and complete rupture of the bronchus. In addition, the anatomical location and the cause of the injury were added to the classification. The levels of injury in the tracheobronchial tree are distinguished anatomically. The third digit distinguishes traumatic, iatrogenic and spontaneous injuries. On the basis of the three-digit classification resulting from these parameters, it is possible to group individual cases together and to develop recommendations for diagnostics and therapy.
