Abstract:
A tracheobronchial foreign body (TFB) can be a life-threatening emergency that requires urgent intervention. TFBs occur most commonly in childhood as a result of aspiration. Traumatic TFB is not frequently reported in the literature. All reported cases of traumatic TFB to date have involved a projectile mechanism of injury. We report a case of a patient who presented with recurrent pneumonia. Flexible bronchoscopy revealed a TFB partially obstructing the right bronchus intermedius. Pathology confirmed the TFB to consist of wood. Further history revealed that the patient experienced an impaling injury on a tree sucker more than 30 years before presentation. Surgery was required to remove the TFB. This case illustrates the importance of the patient's history, and is the first reported case of an impaling injury causing a traumatic TFB.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
