Fibreoptic intubation in cicatricial membranes of the pharynx.

Two patients presented with almost total obliteration of the pharynx. In one, a membrane developed after corrosive poisoning; in the other, the oropharynx was filled with a dense cicatrix in the sclerosing phase of rhinoscleroma. In both patients, a single opening in the membrane provided access to both the larynx and oesophagus. Fibreoptic intubation allowed both a thorough assessment of the pathology and subsequently the passage of a cuffed tracheal tube to secure the airway. To overcome the problem of respiratory obstruction while the fibrescope passed through the opening in the membrane, either rapid intubation, or a technique using pre-oxygenation and voluntary hyperventilation followed by breath-holding during bronchoscopy, was used. The thin calibre and manoeuvrability of the flexible fibreoptic bronchoscope makes fibreoptic intubation an excellent technique of airway management in cicatricial membranes of the pharynx.
