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.
