The use of the Montgomery T-tube in difficult paediatric airways.
OBJECTIVE
We report our experience of using Montgomery T-tubes in children.


METHODS
A retrospective review of medical records was performed. Data collected included particular clinical circumstances, the details of usage of the tube, and the eventual outcome.


RESULTS
Between January 1999 and October 2003, our unit performed 293 tracheostomies, 76 laryngotracheal reconstructions and 31 other major airway procedures in children. 10 children have had a Montgomery T-tube inserted. Nine were boys. In eight cases, the T-tube was used because of severe granulations and subsequent fibrotic narrowing in the subglottis after laryngotracheal reconstruction surgery. These children had undergone between one and four major procedures prior to T-tube placement. In the other two cases, the T-tube was used to stent severe glottic and supraglottic stenosis (due to previous laser surgery for papillomas in one case and congenital ectodermal dysplasia in the other). At the time of T-tube placement the children were aged 2-18 years (median 8 years). The tube was initially fitted so as to protrude above the glottis in all cases. In one case, the T-tube was removed on the first post-operative day. One tube was removed after a week due to severe crusting. One tube blocked after 2 weeks. One child had re-stenosis in the supraglottis necessitating the placement of a T-tube with a longer upper limb. Two children have subsequently died from non-airway causes. Two children still have their T-tube in situ, one of whom is due to have it removed in the next few weeks. Six have been successfully decannulated and are well.


CONCLUSIONS
The Montgomery T-tube provides a useful adjunct to the management of a small number of children with the most difficult airway problems. Its use can be problematic, however, and requires awareness of its specific complications. We have confined usage to complex stenoses where a reconstruction would be inappropriate, or (in one instance) to stent an unsupported larynx after revision reconstruction (tracheal resection).
