Area of Science:

  • Anesthesiology
  • Oral Surgery
  • Anatomy

Background:

  • Direct tracheal laryngoscopy poses a risk of mandibular dislocation.
  • The temporomandibular joint (TMJ) is a complex structure involving bilateral simultaneous movement.
  • The lateral pterygoid muscle plays a key role in mandibular dislocation.

Observation:

  • Mandibular dislocation during laryngoscopy causes significant patient pain.
  • Prompt recognition and treatment are essential for managing this complication.
  • Dental relocation techniques can be adapted for nurse anesthetists.

Findings:

  • The lateral pterygoid muscle's action can dislocate the mandibular condyle and articular disc.
  • Intraoral bimanual relocation is an effective method for reducing mandibular dislocations.
  • This technique, typically used by dentists, can be performed by nurse anesthetists.

Implications:

  • Nurse anesthetists can be trained to manage mandibular dislocations effectively.
  • Implementing this technique can improve patient outcomes and reduce procedural complications.
  • This knowledge enhances the safety and scope of practice for nurse anesthetists during airway procedures.
