	Chapter 21: The esophagus, trachea and main bronchi
		The right main bronchus may be considered as having (1) an upper (eparterial) part, from which the segmental bronchi for the upper lobe arise, and (2) a lower part, from which the segmental bronchi for the middle and lower lobes emerge (fig.
		The upper lobar bronchus may be considered as having (1) an upper division and (2) a lower, or lingular, division.
		Note also the right and left domes of the diaphragm (on the left and right sides of the illustration, respectively) and the fluid level in the stomach (fl arrow).

	SOUTH AFRICAN PULMONOLOGY SOCIETY
		Repeated bronchoscopies were required to remove secretions from the right main bronchus as this was approximately 90% occluded causing the right middle and lower lobes to collapse.
		During the operation the right main bronchus had initially to be plugged and later intermittently occluded to ventilate the patient.
		Approximately 80% of the injuries occur in the main bronchi either near the junction to the trachea or near the midpoint of the bronchus.

	Gross Description -- Case 181 (Site not responding. Last check: 2007-10-29)
		The right main stem bronchus showed a 5 X 3 X 1 cm irregular, soft, yellow-brown mass which was located close to the origin of the right main bronchus.
		The rest of the right bronchus was necrotic and contained a large amount of mucopurulent fluid.
		The rest of the right upper lobe was soft and necrotic, with a round central cavity, 6.5 cm in diameter.

	Indian Pediatrics - Editorial
		The left main bronchus can be visualized in its entirety from the carina, after turning towards the left, and even then it takes a curving course so that its bifurcation cannot be seen from the carina.
		Beyond the origin of the right upper lobe bronchus, the right main stem bronchus continues as the bronchus intermedius.
		This bronchus may extend for 2-2.5 cm at which point it gives rise to the middle lobe bronchus anteriorly, the superior segment of the right lower lobe posteriorly and the right lower lobe bronchus that divides into basilar segments.

	eMedicine - Tracheobronchial Tear : Article by David W Light IV, MD
		Since the left main bronchus has a longer mediastinal course than the right, injury to the left main bronchus is more likely to cause a pneumomediastinum, while injury to the right main bronchus is more likely to cause a pneumothorax.
		In an uncomplicated pneumothorax, the bronchus remains fixed at the hilum, and the peripheral lung retracts from the parietal pleura toward the hilum.
		An obstruction of the right main bronchus is consistent with a bronchial tear.

	Indian Pediatrics - Editorial
		The trachea and heart were shifted to the right and the air entry was poor in the right lower half of the chest.
		The right main bronchus was found to be transected at about 1.5 cm from the carina, and the other end was somewhat buried into the collapsed lung near its hilum.
		Various mechanisms of injury are compression of tracheobronchial tree between the sternum and the vertebral column resulting in distraction of the carina, shearing of bronchus by rapid deceleration and rapid increase in tracheo-bronchial pressure as a result of crush injury with a closed glottis(1,5).

	eMedicine - Foreign Bodies, Esophagus : Article Excerpt by: Michael R Bye, MD
		Most foreign bodies lodge in the right main bronchus, bronchus intermedius, or the right lower lobe bronchus.
		The left main bronchus is smaller than the right main bronchus and is slightly angled.
		In the supine child, material usually enters the right main bronchus but then falls into the orifice of the right upper lobe, which is dependent in the supine position.
