"Occult" posterior laryngeal cleft.

G F Tucker, J Maddalozzo

    The Laryngoscope
    |June 1, 1987

    Summary
    This summary is machine-generated.

    A new posterior cricoid defect, causing airway obstruction, has been identified. This previously overlooked condition presents as subglottic stenosis and requires specific diagnostic methods.

    Area of Science:

    • Otolaryngology
    • Anatomical Pathology

    Background:

    • Subglottic stenosis can cause significant airway obstruction.
    • Existing diagnostic methods may overlook certain laryngeal anomalies.

    Observation:

    • A previously undescribed midline deficiency of the posterior cricoid cartilage was identified.
    • The overlying mucosa of this defect was intact.

    Findings:

    • This anatomical variation presents clinically as subglottic stenosis, primarily affecting the transverse diameter.
    • Symptoms are indicative of airway obstruction rather than laryngeal incompetence.

    Implications:

    • This finding suggests a potential underdiagnosis of this specific cricoid defect.
    • Modified postmortem examination techniques, such as serial horizontal sectioning of the unsplit larynx, are crucial for accurate diagnosis.
