Endoscopic treatment of acquired subglottic stenosis in children: Predictors of success 10.5546/aap.2018.eng.422

Abstract

Subglottic stenosis is a congenital or acquired disease characterized by the narrowing of the airways, from the vocal cords to the lower border of the cricoid cartilage. It is one of the main causes of stridor and respiratory distress in children.More than 90 % of laryngeal stenoses are acquired due to prolonged endotracheal intubation. The pediatric management of subglottic stenosis is complex and may be affected by different factors that have an impact on the final outcome. Treatment may involve endoscopic procedures and/or open surgeries.Here we describe our experience in 35 patients with acquired subglottic stenosis who underwent endoscopic treatment with rigid dilation and identify the potential predictors of success of this technique.

Subglottic Stenosis After Endonasal Resection of Juvenile Nasopharyngeal Angiofibroma

“…It can present as a life-threatening airway obstruction in pediatric patients, warranting a high degree of clinical suspicion [8]. Over 90% of trauma leading to SGS is from prolonged endotracheal intubation [9]. However, external trauma from penetrating, blunt, and strangulation injuries to the oropharyngeal region can also result in acquired SGS [10].…”

Quiste subglótico adquirido como causa inhabitual de estridor en pediatría. Revisión de la literatura a propósito de un caso

“…La más descrita corresponde a la estenosis subglótica circunferencial, asociado a la presencia de múltiples quistes y su resección 5 . De manera global, hasta el 90% de los niños con intubación tendrán secuelas agudas secundarias a ésta, y la incidencia de estenosis subglótica va de 1-8% de los pacientes con intubación prolongada 15 . Schweiger et al, evidenciaron, por su parte, una tasa de hasta 11.38% de 123 niños post intubados que presentaron estenosis subglótica diagnosticada por nasofibroscopía 16 .…”

Ongoing Laryngeal Stenosis: Conservative Management and Alternatives to Tracheostomy

“…Definition of acute lesions comprises those identified in <30 days since extubation (3,4). Moderate to severe lesions pose the highest probability of progressing to chronic stenosis.…”
