Objective: Cricotracheal resection (CTR) is being increasingly used in the treatment of children with severe laryngotracheal stenosis. In this institution the majority of children are treated with CTR as a salvage procedure having undergone previous unsuccessful laryngotracheal reconstruction (LTR). Selected children have undergone CTR as a primary procedure (without previous LTR). The objective of this study is to examine the outcome for children undergoing cricotracheal resection as a primary procedure for severe laryngotracheal stenosis.
Method: analysis from prospectively collected database.
Results: 17 patients underwent CTR without previous LTR or anterior cricoid split between October 1994 and September 1998. All the patients had grade 3 or 4 stenosis. After a minimum of 1 year follow up 15 children are decannulated. Five children required further surgery to achieve this. Two children still have tracheostomies. Both had extended procedures. One included bilateral arytenoid abduction for bilateral vocal cord paralysis in a patient with quadraparesis following transverse myelitis. The other child, who suffered from multiple congenital anomalies, underwent a concurrent posterior cricoid cartilage graft. Nine patients had good voice post-operatively, five had acceptable voice and three had weak or no voice.
Conclusion: the early experience for CTR in children as a primary procedure achieved an overall decannulation rate of 88% after 1 year follow up in children with severe laryngotracheal stenosis. Five children required further surgery to achieve this. The voice outcome was variable. CTR is an alternative primary procedure to LTR for severe laryngotracheal stenosis in children. The relative indications for these procedures are discussed.
