Bottom Line: Significant gender differences were found in all the parameters measured except for the angle of the right upper lobe bronchus.There are no statistically significant correlations among these parameters.Significant gender differences exist in the dimensions of the trachea, with the exception of the Right upper bronchial angle (RUA).

ABSTRACT

Objective: To ascertain accurate measurements of, and the relationships between, the normative parameters of the tracheobronchial trees in the Chinese population using multi-slice spiral computed tomography (CT) and multi-planar reconstruction (MPR).

Materials and methods: Measurements were performed on 2107 patients who underwent thoracic CT scans in the PLA General Hospital. The lengths of the trachea and the main stem bronchi, and the sizes of the subcarinal angle were obtained through CT or MPR imaging. Multi-variance analyses were performed to detect potential correlations between obtained parameters.

Results: The mean length of the trachea was 104.9 ± 13.4 mm (107.8 ± 13.2 mm for men and 101.4 ± 12.8 mm for women). The mean lengths of the right and left main stem bronchi were 13.6 ± 4.3 and 48.3 ± 6.5 mm, respectively. The right bronchus angle and the left bronchus angle were 34.9 and 42.5 degrees, respectively. Significant gender differences were found in all the parameters measured except for the angle of the right upper lobe bronchus. There are no statistically significant correlations among these parameters.

Conclusions: The normal reference values and the likely ranges of distribution of the tracheobronchial trees in the Chinese population have been established. Significant gender differences exist in the dimensions of the trachea, with the exception of the Right upper bronchial angle (RUA).

Mentions: The tracheal lengths (TL) were significantly smaller in the two oldest age groups than in the other six age groups (P < 0.001), as shown in Fig 3 which plots the TL against age in both the male and female subjects. The AP-mcTD distribution curve against age in both the male and female subjects is presented in Fig 4. The Tr-mcTD distribution curve against age in both the male and female subjects is presented in Fig 5. The mean values of the AP-mcTD and the Tr-mcTD for each age group and either gender are presented in Table 6.
