[Mouth mask method for fiberoptic tracheal intubation in difficult intubations].

We tried 72 fiberoptic tracheal intubations (FTI) using a mouth mask in difficult intubation cases. In this method, ventilation is performed via only the mouth using a mask applied over the mouth (mouth mask) and FTI can be done via a nostril with no hindrance from the mask in anesthetized patients. We have been using an infant or child type Seal Mask (Gibeck Respiration) for the mouth mask or a specially made mouth mask.
