[Comparison of difficulty in airway intubation with aging. Study on 71 subjects who had an airway intubation 20-or-more years earlier].

Background: Although there are reports targeting children with micrognathia, there is no report how orotracheal intubation difficulty of normal adult patients changes with aging. We surveyed orotracheal intubation episodes after more than 20 years from the initial surgery.

Methods: Seventy one patients underwent general anesthesia again after 23 years in average.
