    Area of Science:

    • Otolaryngology
    • Laryngology
    • Medical Informatics

    Background:

    • Direct laryngoscopy is a key diagnostic tool for laryngeal conditions.
    • Understanding historical trends in laryngeal pathology aids current clinical practice.
    • Computer technology offers novel methods for retrospective medical data analysis.

    Purpose of the Study:

    • To retrospectively analyze direct laryngoscopies performed in 1978.
    • To identify common laryngeal pathologies, symptoms, and risk factors.
    • To evaluate the utility of computer technology in analyzing laryngoscopy data.

    Main Methods:

    • Retrospective analysis of direct laryngoscopy cases from 1978.
    • Data collected and analyzed using computer technology.

  • Demographic, symptomatic, diagnostic, and procedural data were reviewed.

    • Main Results:

    • The study population (n=?) averaged 50.4 years, with 54% males.
    • Hoarseness (83.6%) was the most frequent symptom.
    • Vocal cord polyps (benign) and squamous cell carcinoma (malignant) were most common diagnoses.
    • Males predominated in most conditions except vocal cord polyps.
    • Indications like "tumor," sore throat, dysphagia, and hemoptysis were linked to malignancy.
    • Voice abuse associated with polyps; tobacco/alcohol with cancer.
    • 85% of procedures used general anesthesia; two-thirds used suspension microlaryngoscopy.

    Conclusions:

    • Direct laryngoscopy data from 1978 reveals key insights into laryngeal pathology demographics and risk factors.
    • Computer analysis of historical data provides valuable epidemiological information.
    • Findings underscore the association of specific symptoms and lifestyle factors with benign and malignant laryngeal diseases.
