Figure 2. Bronchoscopic images of the patient’s tracheal lumen before (A, B) and after (C) integral restitution. Image A was taken in 2016, image B in 2019, and image C in 2022. A and B show endotracheal hair growth and fibrinous coating. In C, hair growth had been successfully terminated and the tracheal skin graft appears structurally improved in direct comparison. Additionally, there is a small scar of laser coagulation in the same location as in A and B.
