ABSTRACT<\/strong><\/p>\n

Background: <\/strong>Variations are common in human body and some of these variations are significant clinically. Knowledge of the variations in the length and diameter of trachea will be useful for anaesthetist and variations in the branching pattern of bronchial tree will be important for pulmonologist, surgeons, physicians and anatomists.<\/p>\n

Aim:<\/strong> The present study was conducted to observe the variations in the length and diameter of trachea and also variations in the branching pattern of bronchial tree in both lungs.<\/p>\n

Materials and Methods: <\/strong>This study was carried out by dissection in 50 pairs of lung irrespective of age, sex, socio-economic status or pathological bias obtained from the embalmed cadavers of Department of Anatomy, Thanjavur Medical College, Tamilnadu, India.<\/p>\n

Results:<\/strong> The diameter of trachea was found to be greater than 2.5cms in 2% and in 4% it was less than 1.8cms. The length of the trachea was found to vary from 6.5cms to 16cms with the mean of 11.2cms. The length of right primary bronchus was found to vary from 1cm to 3 cm with an average of 2cm. The length of left primary bronchus was found to vary from 3.5cm to 5cm with an average of 4.4cm. The angle of right primary bronchus was found to be acute in all specimens with an average of 37o<\/sup>. The angle of left primary bronchus varied from 65o<\/sup> to 80o<\/sup> with an average of 74o<\/sup>. Sub superior bronchus was present in the right lower lobe in 92% and was found in all the specimens of left side.<\/p>\n

Conclusion: <\/strong>This study showed variations in the parameters of trachea and also in the branching pattern of the bronchial tree which is significant for the clinicians. These variations can be well documented by other method of studies like cast preparation.<\/p>\n
