stenosis is seen under the glottis .C、D CT photo of the patient with
laryngeal web type III and IV,C The glottis segment is narrow,D The
subglottic area is narrow.
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

Figure-4 The cricoid cartilage affected was incised to remove the
subglottic stenotic lesion tissues, Afterwards, the cricoid cartilage
was repaired and reconstructed with the hyoid bone.
