Open division, cricothyroid ligament

Last edited: 4/15/2026

Overview

Open division of the cricothyroid ligament, also known as cricothyrotomy, is an emergency procedure performed to establish an airway in situations where conventional intubation is impossible or contraindicated, such as severe upper airway obstruction 1.

Diagnosis

  • Clinical Indication: Severe upper airway obstruction unresponsive to basic airway maneuvers 1.
  • Contraindications: Not applicable for diagnosis; primarily a therapeutic intervention 1.
  • Management

  • First-Line Treatment: Percutaneous needle cricothyrotomy or surgical cricothyrotomy 1.
  • Training Approach: The 4-stage approach to skill training may result in shorter performance time and fewer attempts to successfully perform cricothyrotomy within 60 seconds compared to traditional teaching methods 1.
  • Special Populations

  • Pediatrics: Not specifically addressed in the provided abstracts 1.
  • Elderly: Not specifically addressed in the provided abstracts 1.
  • Comorbidities: Not specifically addressed in the provided abstracts 1.
  • Key Recommendations

  • Utilize the 4-stage approach for training medical students in cricothyrotomy to potentially improve procedural efficiency and reduce the number of attempts needed for successful execution within 60 seconds (Evidence: Moderate) 1.
  • Perform cricothyrotomy as an emergency intervention for severe upper airway obstruction when conventional intubation is not feasible (Evidence: Expert opinion) 1.
