The aims of this study were to review the outcomes of the distinct endoscopic and surgical procedures and to suggest a technical modication for one of them. Methods: Retrospective review of patients with the diagnosis of laryngeal stenosis treated in an academic tertiary care institution between 2000 and 2017. The following variables were analyzed: demographic data, endoscopic ndings including anatomic type and severity of the lesion, associated anomalies, type of treatment, outcomes, and time of follow-up. Results: Seventy-eight children were included in the study (39 boys) with a median age at diagnosis of 9 months, and 33 (42.3%) showed an associated anomaly. Lesions were acquired in 84.6% of cases and the subglottic region was most frequently involved (77%). Thirty patients (38.4%) had a severe stenosis (Myer-Cotton grades III and IV) and a tracheotomy was performed as an initial treatment in 38 patients (48.7%). Overall, 91% of endoscopically or surgically treated patients showed a good outcome and the decannulation rate in the series was 79.4%. Fourteen patients were managed conservatively. Median follow-up was 29 months (I.R. 1060 m.) Conclusions: Laryngeal stenosis in children is usually acquired and exhibit a wide range of anatomic presenta- tions. Endoscopic therapeutic procedures may be useful in the management of low grade immature stenosis. Re- constructive surgical techniques may provide a high success rate with an appropriate selection of candidates. © 2018 Elsevier Inc. All rights reserved. Laryngeal stenosis is a rare disorder in children but relatively fre- quent in the setting of prolonged ventilatory support in intensive care units and pediatric airway units. These lesions can be congenital or ac- quired and the subglottic region is most frequently involved [1]. Al- though diagnostic work-up is well established and relies basically on endoscopic ndings, comprehensive management guidelines are lack- ing and treatment strategies depend on the particular airway team ex- perience and the specic patient's condition. The objective of this study was to show our experience in the man- agement of children with laryngeal stenosis focusing on the anatomic features, severity, type of treatment and outcomes. Additionally, a mod- ication of one of the reconstructive surgical techniques is proposed. 1. Materials and methods We performed a retrospective review of all patients with the diagno- sis of laryngeal stenosis in our unit between January 2000 and Decem- ber 2017. This study was carried out with the approval of our institutional ethical committee. Clinical charts and laryngo-tracheo- bronchoscopy reports were reviewed, and the following data were col- lected: demographic facts, clinical symptoms, endoscopic ndings in- cluding anatomic type and severity of the lesion, associated anomalies, treatment modality, outcomes, and time of follow-up. Main outcome measures were decannulation rate in those patients with a previous tra- cheostomy and clinical improvement in patients without it. Clinical im- provement was dened as disappearance of stridor and better exertion tolerance, a signicative relieve of airway obstruction avoiding trache- otomy, and improved pulmonary function tests when available. A neck-chest radiograph was obtained in every case as well as a tra- cheal aspirate sample for microbiological study. Every patient underwent a laryngo-tracheo-bronchoscopy (LTB) even if the diagnosis Journal of Pediatric Surgery xxx (xxxx) xxx Corresponding author. E-mail address: janton.hdoc@salud.madrid.org (J.L.
