Aim: Knowledge of variations in patterns of bronchial tree is useful for diagnosis and surgery of chest diseases. In our study we aimed to expose the variations in patterns of bronchial tree. Material and Methods: In this study 15 right and 15 left lungs from 15 cadavers were used. All branches of each lobe were dissected from the surrounding parenchyma. Ramification of bronchial tree was displayed. The patterns of segmental and some subsegmental bronchi were determinated and whether accessory bronchus present or not was examined. Results: We identified that most common variations in the patterns of bronchial tree are B6c, B6a+6b; B7, B8, B9+10 in right side and B1+2, B3; B7+8, B9+10 in left side. The most common accessory bronchi were bronchus subsuperior arising from B10 in right side, and bronchus subsuperior and bronchus subsuperior arising from B10 in left side. Many researchers used different terminologies for identification of branches of bronchial tree. We commonly found patterns of B1+2 (60%) and B7+8 (79,99%) in left lungs. Conclusion: It is identified that there are 8 segmental bronchi on the left. This study will be helpful for many radiological and anatomical studies.
