Introduction: Tracheal anatomy is useful for clinicians to select correct size of endotracheal tube. The study can be done by both invasive and non-invasive techniques like cadaveric dissection(CD), Computed Tomography (CT) scan. In present study we measured diameter, length, cross sectional area, volume of human trachea on CT scan images and the data was compared with that of the other studies.
Method: In this prospective study normal chest CT scan images of 110 cases (69 males and 41 females) were studied. Chest CT scans were performed on 64 slice CT scanner. Measurements were obtained using Digital Imaging and Communications in Medicine (DICOM) software. The minimum and maximum values in study population were established for each parameter. The relationship of all study parameters with height and weight was assessed using Pearson’s correlation. The regression analysis of significantly correlating variables was done with height and weight as predictors.
In males: Height correlated significantly with A-P diameter and transverse diameter & Weight correlated significantly with A-P diameter and CSA.
The weight was found to be a weak predictor of A-P diameter, cross sectional area, and volume.
The height was found to be a weak predictor of length, and transverse diameter.
In females: None of the study parameter showed significant correlation with either height or weight. Neither height nor weight found to be the predictor of dependent variables.
Conclusion: Practical applications of the data may be useful in the configuration and design of tracheostomy tubes, endotracheal tubes.
