Abstract:
OBJECTIVE To summarize the clinical features and treatment methods of subglottic cysts in infants.METHODS A single-center retrospective study was conducted,enrolling twelve pediatric patients with subglottic cysts who were treated at Beijing Children's Hospital,Affiliated to Capital Medical University,between December 2016 and October 2024.Clinical data were collected and analyzed,including patient age,body weight,perinatal history,presenting symptoms,findings from flexible laryngoscopy and imaging studies,as well as surgical treatment modalities.RESULTS Among the 12 patients,8 were male and 4 were female,with a median age of 7 months.Preterm infants accounted for 83.3%(10/12),low birth weight was observed in 58.3%(7/12),and 75%(9/12)had a history of tracheal intubation.The primary clinical manifestations included stridor,respiratory distress,and feeding difficulties.All patients were diagnosed by laryngoscopy and imaging studies,which confirmed the presence of subglottic cysts.Among these,9 were located on the right side and 3 on the left.All patients underwent subglottic cyst excision under general anesthesia using suspension laryngoscopy combined with endoscopy.Among them,two cases experienced recurrence and required a second surgical procedure three months postoperatively.Histopathological examination revealed a cyst wall lined by stratified squamous epithelium and pseudostratified ciliated columnar epithelium.All patients were followed up for a period ranging from 6 months to 6 years,with no recurrence observed during this time.CONCLUSION Infants presenting with stridor and dyspnea should undergo prompt laryngoscopy for definitive diagnosis.Subglottic cysts should be highly suspected in preterm,low-birth-weight infants with a history of intubation who develop stridor or respiratory distress during development.Once diagnosed,surgical intervention should be performed promptly to avoid the need for a tracheostomy.Surgical excision under general anesthesia using suspension laryngoscopy combined with endoscopy is an effective treatment for subglottic cysts.
