Abstract
Objective:Explore the clinical diagnosis and treatment strategies of recurrent multiple chondritis in children with airway involvement as the main cause. Methods:From June 2021 to May 2023, five children with relapsing polychondritis were admitted to our department, all of whom met the Damiani criteria. Tracheotomy was performed in all five patients. Endoscopy indicated subglottic stenosis, with one case classified as grade Ⅲ and four cases as grade Ⅳ according to the Myer-Cotton classification. Enhanced CT scans of the head and neck showed fixed lumen narrowing and stenosis, including thickening of the soft tissue in the laryngeal cavity and partial absorption of the laryngotracheal cartilage anterior wall. In one patient, tracheal wall thickening and deformation with stenosis and calcification involved the posterior tracheal wall. One patient underwent "laryngeal tracheal reconstruction with hyoid graft, T-tube implantation, and bioabsorbable corticosteroid-eluting stent implantation", while three patients underwent "balloon dilatation, T-tube implantation, and bioabsorbable corticosteroid-eluting stent implantation" . Follow-up was performed every two months after the initial surgery, and three bioabsorbable corticosteroid-eluting stents were placed on the upper left, upper right, and lower T-tube, respectively, during this time. The entire follow-up period was six months. Results:All the 5 cases were in the outpatient department, of which 1 case had been extubation, 3 cases were still in the outpatient follow-up, and the remaining 1 case was still being treated in the rheumatology and immunology department due to poor control of the primary disease. Conclusion:In relapsing polychondritis children with airway involvement, tracheotomy could be used to quickly improve the symptoms of dyspnea in the disease progression. In the stable stage of the disease, the surgical method of 'Balloon dilatation + T-tube implantation + Bioabsorbable corticosteroid-eluting stents implantation' was adopted to reduce the secondary injury caused by surgical trauma as much as possible and improve the survival and quality of life of the children.
