Boyden classification of bronchi
Citation, DOI & article data
The Boyden classification of bronchi refers to the standard nomenclature used to describe bronchopulmonary segmental anatomy.
Each lung has 10 segments, however, on the left, the first two segments share a common trunk and are hence B1/2. Also given the shared trunk on the left of the lower lobe anterior and medial basal segments forming the anteromedial segment, B7 is omitted.
- right upper lobe
- right middle lobe (or more correctly - just middle lobe)
- right lower lobe
The left lung is subdivided into two lobes and thereby, into eight segments. The notation in brackets refers to the Boyden classification.
