“…Our analysis of the results, therefore, permits us to draw some conclusions: (a) OA exhibits a high number of morphological variations of the mediastinal structure, some of which are not clinically influential; (b) the use of routine airway assessment by endoscopic procedure is mandatory in all cases of OA before the fourth month of life, and in TM positive cases CT examination was carried out using axial helical computed tomography with a contrast medium; (c) correction of the TM cannot be always effected using a standard operation that does not include consideration of any multiform structural anomalies of the mediastinum, and for this reason we always recommend a surgically 'tailored' approach based on the endoscopic and radiology findings; (d) corrective surgery must be performed using one 'window of access' to the airway, differently from Gross' traditional approach, and we think that the use of a low cervical incision with a split of the sternal manubrium, as recommended by some surgeons [20,21], meets this need better; (e) the importance of the use of intraoperative broncoscopy in the correction of a TM.…”
