Tracheal airway obstruction: a custom made tracheostomy tube.

Tracheal obstruction is encountered in primary malignancy of the trachea and invasion or compression from extrinsic lesions. No commercially available tracheostomy tube can be suitable for all cases. A flexible cannula of adjustable length can be produced from universally available anaesthetic equipment. Intubation is facilitated by the use of fibreoptic endoscopy.
