    Post-intubation laryngeal immobility stems from mechanical arytenoid issues, not nerve damage. Diagnosis often requires surgery, highlighting the need to examine surgical specimens.

    Area of Science:

    • Otolaryngology
    • Laryngology
    • Pathology

    Context:

    • Post-intubation laryngeal immobility is a recognized complication.
    • Existing theories often attribute this immobility to neurogenic causes.
    • Clinical and paraclinical examinations frequently fail to provide conclusive diagnoses.

    Purpose:

    • To investigate the underlying mechanical causes of post-intubation laryngeal immobility.
    • To challenge existing neurogenic theories of etiopathogenicity.
    • To emphasize the diagnostic value of surgical specimen analysis.

    Summary:

    • This study analyzed 14 cases of post-intubation laryngeal immobility.
    • Findings indicate mechanical lesions involving the arytenoids (synechia, ankylosis, fibrosis) are the primary cause in all cases.

  • Median thyrotomy is often necessary for definitive diagnosis, underscoring the importance of examining arytenoidectomy specimens.

    • Impact:

    • Suggests a re-evaluation of neurogenic theories for post-intubation laryngeal immobility.
    • Highlights the critical role of mechanical factors and surgical pathology in understanding this condition.
    • Informs diagnostic and therapeutic strategies for laryngeal dysfunction after intubation.
