198 - Tracheal lesion by cannula tip

198 – Tracheal Granuloma

These smooth protrusions that seem to pile on the posterior tracheal wall or mucous membrane, correspond to granulomas originated by a fearsome situation: the “tracheal cannula tip injury”.

The lack of stable fixation of the pavilion of the tracheostomy cannula against the neck, allows movements of the device that tends to swing on its support in the stoma causing its end or tip of the cannula to damage the tracheal mucosa.
The phenomenon is particularly true when it has been connected to a mechanical ventilation system, adding weight and unwanted movement to the cannula.
