[One case of the basilar invagination that prevented tracheal intubation by Airway Scope].

Airway Scope (AWS, Pentax, Tokyo, Japan) is a very useful intubation assistance tool in the case where intubation is difficult with normal Macintosh laryngoscope. In this case, the operation was planned by general anesthesia in a patient with basilar invagination. We decided to intubate the patient using AWS because difficult tracheal intubation was expected. However, glottis was not confirmed even with AWS in the oral cavity, and we could not intubate with AWS. Therefore, we used a fiberscope, and endotracheal intubation was successful.
