Objectives: Determine the effectiveness of endoscopic surgical treatment of subglottic stenosis (SGS) in children as a primary surgical modality to prevent laryngotracheal reconstruction (LTR) and as treatment for restenosis following primary LTR to prevent revision LTR. Patients: Children undergoing various endoscopic surgical treatments from 1989 to 2006 for SGS. Results: The number of children and success rates per grade of SGS and the number of procedures required to produce a successful result in 29 children initially managed endoscopically included grade I, three of three (100%), 1.3 procedures; grade II, eight of nine (88%), 2.6 procedures; and grade III, 13 of 17 (76%), 3.5 procedures. Of 102 patients undergoing open LTR, 56 of 102 required endoscopic interventions and 41 of 56 (73%) children were treated successfully. Conclusion: Endoscopic intervention can be used to manage SGS either as a primary intervention or to treat reobstruction and restenosis following an open reconstructive procedure. Success rates decline as the severity of stenosis increases.
