Transglottic corticosteroid injection for treatment of soft post-intubation subglottic stenosis: a retrospective analysis of 26 children.

Surgical treatment is generally recommended for severe subglottic lesions following traumatic endotracheal intubation in children. An alternative approach is early transglottic corticosteroid administration to reduce scar formation and prevent the need for subsequent surgical intervention. This technique has been practiced successfully for several decades at the Children's Hospital of Cologne and the outcomes of 26 subsequent patients reviewed in this analysis. All patients who underwent transglottic corticosteroid injection for treatment of post-intubation stridor and dyspnoea between 2012 and 2018 were identified and their records and endoscopy images analysed. Severity of the endoscopic findings was assessed using the Myer-Cotton classification (MCC) and an Expected Need for Surgical Intervention (ENSI) score (1 = inevitable; 2 = very likely necessary; 3 = probably avoidable and 4 = most likely not necessary) was recorded. Treatment was considered successful if the children had a complete resolution of clinical symptoms. A total of 26 patients with a median (range) age of 1.9 (0.02-7.2) years and weight of 9.8 (1.8-25) kg were identified and included into the analysis. Endoscopic images were available for 22 children. All children underwent transglottic corticosteroid injection prior to any potential surgical treatment. A total of 22 patients (85%) improved following transglottic corticosteroid injection including 4 of 5 patients with a MCC = 3 and ENSI = 1 avoiding surgical intervention. None of the patients experienced a deterioration of clinical symptoms or endoscopic findings. Transglottic corticosteroid injections as first-line treatment in children with severe post-endotracheal intubation trauma can successfully resolve symptoms and prevent invasive surgery.
