Open laryngoplasty (T-tube implantation + hyoid-bone reconstruction of the cricoid cartilage)
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). The cricoid cartilage, thyroid cartilage, and hyoid bone were exposed. 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 was positioned using intraoperative laryngoscopy, and the T-tube should be slightly above the glottis (Fig. 3-F). Afterwards, the cricoid cartilage was repaired and reconstructed with the hyoid bone (Fig. 3-E) and the incision was sutured.
We mention that the reporting guideline has been followed in this study.
