Unexpected difficult intubation due to lingual tonsillar hyperplasia in a thoracotomy patient: intubation with the double-lumen tube using stylet and fiberoptic bronchoscopy.

Lingual tonsillar hyperplasia is rare, and it may cause difficulty with tracheal intubation during induction of general anesthesia. A different orotracheal intubation technique was performed using a double-lumen endotracheal tube, flexible fiberoptic bronchoscope, and a stylet, in an unexpected difficult endobronchial intubation case due to massive lingual tonsillar hyperplasia.
