1.1 Current evidence on the safety and efficacy of endoscopic balloon dilatation for subglottic or tracheal stenosis is inadequate in quantity and quality. Therefore this procedure should only be used with special arrangements for clinical governance, consent and audit or research.
1.2 Clinicians wishing to undertake endoscopic balloon dilatation for subglottic or tracheal stenosis should take the following actions.
Inform the clinical governance leads in their Trusts.
Ensure that patients and their carers or parents understand the uncertainty about the procedure's safety and efficacy, and provide them with clear written information. In addition, the use of NICE's information for patients is recommended.
Clinicians should enter details for paediatric patients having endoscopic balloon dilatation for subglottic or tracheal stenosis onto the Airway Intervention Registry (accessible from any computer connected to the N3 [NHS] network) and for adult patients having the procedure into the ENT UK national audit database.
1.3 Further information from research and collaborative data collection would be useful. This should include clearly defined patient selection criteria and long‑term outcomes. NICE may review this procedure on publication of further evidence.
