Measuring measurements of an airway is verysignificant for interventional bronchoscopists, investigators and clinicians in order to precisely diagnose anatomical anomaliesand detect the pathological alteration along a time or in reaction to therapies.Treating and exploration of images, thoughtful of topicsconnected to the achievement, and for any extent liketopics effect on imaging the tracheobronchial tree, is importantforevaluateddimensions precision and to createactualapplication of advanced techniques. The present workadds to this understandingby providing accurate measurements of the normative parameters of the tracheobronchial trees in the Egyptianresidentsapplying multi-planar reconstruction (MPR)andmulti-slice spiral computed tomography (CT).Six hundreds of persons submit to the Benha University Hospital for performing thoracic CT scans including the dimensions of tracheal and bronchial tree.Tracheallengths(LT)and its transvers diameter (TrTD) and anteroposterior diameter (APTD), the lengths of main stem bronchi as right bronchial length (RBL), left bronchial length (LBL), and the sizes of the right bronchial angle (RBA), left bronchial angle (LBA) were gotten via MPR of CT imaging. Multi-variance analyses were done to identifypossible associations amongacquired measurements.The anteroposterior tracheal diameter (APTD) was 20.13 ± 1.61 mm (22.46 ± 1.81mm for male and 17.81 ± 1.12mm for female).The transvers tracheal diameter(TrTD)was 18.64 ± 1.40 mm (20.92± 1.36 for male and 16.36 ± 1.18 mm for female).The length of the trachea(TL) was 125.88 ± 2.33mm (130.31 ± 2.22 mm for male and 121.46 ± 2.41mm for female). The mean lengths of left main stem bronchus (LBL) andthe right main stem bronchus (RBL)were 48.75 ± 1.88 and32.39 ± 1.11 mm respectively. The right bronchus angle and the left bronchus anglewere 35.68 ± 2.11 and 47.77 ± 1.55 degrees, respectively. The differences regarding the gender were significant in all the dimensions measured, there were significant increasein all parameters with increasing height except for the right and left bronchial angels there were no significant difference with increasing height,and there were no significant change in alltracheobronchial parameters with increasing weight and age. |
