Figure-3 The surgery was performed under general anesthesia with an anesthetic cannula inserted in the place of the tracheal tube in the neck of the child (Fig. 3-A). A portion of the hyoid bone was obtained and trimmed into a pike shape (Fig. 3-B.C). The cricoid cartilage affected was incised to remove the subglottic stenotic lesion tissues, the anaesthetic cannula was removed and a T-tube was inserted (Fig. 3-D). the T-tube should be slightly above the glottis (Fig. 3-F). the cricoid cartilage was repaired and reconstructed with the hyoid bone (Fig.3-E),The photo of T-tube
