    Emergency jaw release during intermaxillary fixation is often too slow. Experienced surgeons were faster, but the time taken by other staff questions the practicality of this emergency measure for patients with facial fractures or deformities.

    Area of Science:

    • Anesthesiology
    • Oral and Maxillofacial Surgery
    • Trauma Management

    Background:

    • Intermaxillary fixation (IMF) is crucial for managing facial fractures and deformities post-osteotomy.
    • IMF presents unique challenges for anesthesiologists, particularly during emergencies.
    • Traditional emergency protocols involve readily available wire cutters for rapid jaw release.

    Purpose of the Study:

    • To evaluate the efficiency of emergency jaw release in patients with IMF.
    • To determine the time required for different medical personnel to release IMF.
    • To assess the practicality of patient- or layperson-assisted jaw release.

    Main Methods:

    • Timing the release of intermaxillary fixation by experienced oral surgeons.
    • Timing the release of intermaxillary fixation by hospital staff involved in patient care.

  • Analysis of release times to assess practicality for emergency scenarios.

    • Main Results:

    • Experienced oral surgeons released fixation in an average of 35.3 seconds.
    • Hospital staff required an average of 2 minutes and 9 seconds for release.
    • Release times by non-specialist staff were deemed impractical for laypersons in emergencies.

    Conclusions:

    • The effectiveness of immediate jaw release using wire cutters is questionable in emergencies like airway obstruction or vomiting.
    • Alternative strategies for managing IMF-related complications are necessary.
    • Anesthesiologists should consider the actual time required for release by various personnel when planning patient care.
