    Summary

    Laryngeal cytology effectively diagnoses low- and intermediate-grade dysplasia. However, it cannot differentiate high-grade dysplasia from invasive cancer, limiting its application to specific recurrent or high-risk lesions.

    Area of Science:

    • Otolaryngology
    • Oncology
    • Pathology

    Background:

    • Laryngeal dysplasia diagnosis is crucial for preventing cancer progression.
    • Accurate diagnostic methods are needed to guide treatment decisions.
    • Cytology offers a less invasive diagnostic approach for laryngeal lesions.

    Purpose of the Study:

    • To evaluate the diagnostic utility of laryngeal mucosal cytology.
    • To determine the limitations of cytology in differentiating dysplasia grades and invasive cancer.
    • To define specific clinical scenarios where cytology is most beneficial.

    Main Methods:

    • Analysis of laryngeal mucosal cytology samples.
    • Correlation of cytological findings with histopathological diagnoses.
    • Review of clinical cases involving recurrent or extensive laryngeal lesions.

    Main Results:

    • Cytology accurately diagnosed low-grade and intermediate laryngeal dysplasia.
    • Cytology could not distinguish between high-grade dysplasia and invasive laryngeal cancer.
    • The method showed potential utility in managing persistent recurrent dysplasias and extensive lesions posing biopsy risks.

    Conclusions:

    • Laryngeal cytology is valuable for low- and intermediate-grade dysplasia.
    • Its role in diagnosing high-grade dysplasia and invasive cancer is limited.
    • Cytology should be reserved for specific conditions like persistent dysplasia or high-risk lesions.
