Objectives:
Whether to perform surgical or conservative treatment for congenital tracheal stenosis (CTS) is controversial. Thus, the computed tomography (CT) criteria for conservative treatment of CTS were investigated.
Methods:
From 2005 to 2017, 28 CTS cases were included. The operative cases and preoperative death cases constituted the required intervention group (group I), and the non-operative surviving cases constituted the observation group (group O). The diameter of the tracheal narrowest part (DTNP) on CT was evaluated as a criterion for non-operative follow-up.
Results:
Chest CT was performed 19 times in 19 group I cases and 18 times in 9 group O cases. The median age of the patients that underwent CT scan examinations was 3.4 months (range 0-25 months) in group I and 22 months (range 0-60 months) in group O. The cut-off values of the non-operative criteria were 40.8% (AUC: 0.82, p < .01) normal for age of the trachea's narrowest part, and 41.6% normal for body weight (AUC: 0.92, p < .01), respectively.
Conclusions:
DTNP is 40% and more of the normal diameter appears necessary for non-surgical management. The present study suggests that the criteria for conservative management of CTS are that the DTNP is not less than 40% of the normal tracheal diameter, with a few symptoms.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
