    Summary
    This summary is machine-generated.

    Laryngoceles are more common than previously thought, often found incidentally in patients undergoing imaging for suspected head and neck cancers. This study found no evidence that laryngoceles are a precursor to cancer.

    Area of Science:

    • Otolaryngology
    • Radiology
    • Oncology

    Background:

    • Laryngoceles are rare air sac outpouchings of the laryngeal ventricle.
    • Historically diagnosed clinically in symptomatic individuals, often mistaken for other conditions.
    • Increased use of advanced imaging for head and neck cancers leads to more incidental laryngocele diagnoses.

    Purpose of the Study:

    • To determine the incidence of laryngoceles in patients undergoing imaging for suspected laryngeal or hypopharyngeal cancer.
    • To evaluate the relationship between laryngoceles and carcinoma.
    • To identify effective diagnostic radiographic procedures for laryngoceles.

    Main Methods:

    • Retrospective review of 2,068 patients at M.D. Anderson Hospital and Tumor Institute.
    • Patients were undergoing diagnostic radiographic procedures for suspected laryngeal or hypopharyngeal cancer.

    Related Experiment Videos

  • Analysis of radiographic findings including lateral soft tissue neck radiography, anteroposterior laryngeal tomography, and contrast laryngography.

    • Main Results:

    • A 4.2% incidence (87 of 2,068 patients) of laryngoceles was identified.
    • Laryngoceles were classified into internal, external, and combined types.
    • No substantive evidence was found to support laryngocele as a precursor to carcinoma, despite historical discussion.

    Conclusions:

    • Laryngoceles are more prevalent than previously reported, frequently diagnosed incidentally.
    • Advanced radiographic techniques are effective in diagnosing laryngoceles.
    • Current evidence does not link laryngoceles as a precursor to laryngeal or hypopharyngeal cancer.
