    Proceedings of the Royal Society of Medicine
    |November 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    Congenital subglottic stenosis and enlargement occur in a small percentage of infants and children. This study quantifies the incidence of these variations in subglottic airway size.

    Area of Science:

    • Pediatric Otolaryngology
    • Pediatric Airway Research
    • Congenital Airway Abnormalities

    Background:

    • Subglottic airway abnormalities can impact pediatric respiratory health.
    • Understanding the incidence of congenital variations is crucial for diagnosis and management.
    • Previous data on subglottic size variation incidence in large pediatric cohorts is limited.

    Purpose of the Study:

    • To investigate the incidence of congenital subglottic stenosis and enlargement in a large cohort of infants and children.
    • To provide precise epidemiological data on the prevalence of mild and moderate subglottic size variations.
    • To establish a baseline for future research on pediatric subglottic airway disorders.

    Main Methods:

    • Retrospective analysis of subglottic airway measurements in 3304 pediatric patients.

  • Classification of stenosis and enlargement into mild and moderate degrees.
  • Calculation of incidence rates for each category of subglottic variation.

    • Main Results:

    • Congenital subglottic stenosis was identified in 0.91% (mild) and 0.06% (moderate) of patients.
    • Congenital subglottic enlargement was observed in 0.7% (mild) and 0.06% (moderate) of patients.
    • The overall incidence of significant subglottic variation was low but present in the studied pediatric population.

    Conclusions:

    • Congenital subglottic stenosis and enlargement represent uncommon findings in the pediatric population.
    • The study provides valuable incidence data for pediatric subglottic airway variations.
    • These findings aid in the clinical assessment and management of infants and children with potential airway issues.
