Nonorganic upper airway obstruction.

E U Neel, D L Posthumus

    Journal of Adolescent Health Care : Official Publication of the Society for Adolescent Medicine
    |September 1, 1983
    PubMed
    Summary

    Functional upper airway obstruction can cause severe breathing difficulty. Psychotherapy and relaxation techniques effectively treated these cases, highlighting the importance of diagnosing functional causes.

    Area of Science:

    • Pulmonology
    • Psychiatry

    Background:

    • Upper airway obstruction presents diagnostic challenges when organic causes are absent.
    • Severe dyspnea and stridor necessitate thorough evaluation to rule out life-threatening conditions.

    Observation:

    • Two cases presented with severe dyspnea and stridor due to unexplained upper airway obstruction.
    • Standard medical evaluations failed to identify any structural or organic etiology for the symptoms.

    Findings:

    • Functional upper airway obstruction was diagnosed based on clinical presentation and exclusion of organic causes.
    • Pulmonary function studies, specifically flow-volume loops, revealed characteristic abnormalities.
    • Abnormalities included reduced inspiratory vital capacity compared to expiratory vital capacity and discordant inspiratory flow limitation with airway resistance.

    Implications:

    • Psychotherapy and relaxation techniques proved successful in managing functional upper airway obstruction.
    • Accurate diagnosis of functional etiology is crucial to avoid inappropriate interventions.
    • Identifying functional causes ensures appropriate patient care and prevents unnecessary medical treatments.
