Diagnosis and treatment of the cartilaginous subglottic web in children / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To explore the methods of preoperative diagnosis, evaluation and surgical treatment of the subglottic web in children. METHODS We analyzed the clinical manifestations, electronic laryngoscopy results, tracheal endoscopy and airway CT results of 4 children cases with congenital laryngeal cartilaginous subglottic web (1 case of type IV and 3 cases of type III) from August 2014 to March 2018. All of the 4 patients underwent a laryngofissure plus submucosal resection of cartilage web and short-term stenting. RESULTS Two cases underwent preoperative tracheotomy at 13 month old, 1 case at 6 month old. One case underwent tracheotomy at the same time of laryngoplasty. Two children indwelled the stents for 7 days and 11 days after operation and removed the stent by themselves. Other 2 cases removed the stent by the doctor at 14 day after operation. After removing the stents, the 4 cases underwent a pluging of the tracheotomy instantaneously. After 3 to 5 months of continuously pluging of the tracheotomy, all cases successfully removed the tracheal cannula. CONCLUSION For children with congenital laryngeal cartilaginous subglottic web of type III or type IV, the operation of laryngofissure plus submucosal resection of cartilage web and short-term stenting is the good choice with a high extubation rate and no complications.
