    A rare case of glottic obstruction occurred after tracheal tube removal due to arytenoid dislocation. This airway emergency resolved spontaneously with continued coughing, highlighting a unique self-correcting mechanism.

    Area of Science:

    • Otolaryngology
    • Anesthesiology
    • Critical Care Medicine

    Background:

    • Post-extubation airway obstruction is a potential complication following tracheal intubation.
    • Glottic and supraglottic pathologies can lead to significant respiratory distress.

    Observation:

    • A patient developed severe glottic valvular obstruction immediately after extubation.
    • The obstruction was attributed to bilateral arytenoid dislocation, likely caused by coughing against the tracheal tube.

    Findings:

    • The arytenoid dislocation resulted in a critical airway narrowing.
    • Spontaneous resolution of the obstruction occurred following a subsequent episode of coughing.

    Implications:

    • This case highlights an unusual, self-resolving cause of post-extubation airway obstruction.

  • Understanding arytenoid dynamics during coughing is crucial for managing airway complications.
  • Clinicians should consider arytenoid dislocation in the differential diagnosis of acute post-extubation stridor.
