Summary

Idiopathic subglottic stenosis (ISS) is a rare condition. Endoscopic laser surgery effectively treats thinner ISS, while complex cases may require laryngotracheal reconstruction, potentially benefiting from mitomycin-C.

Area of Science:

  • Otolaryngology
  • Respiratory Medicine
  • Inflammatory Diseases

Background:

  • Idiopathic subglottic stenosis (ISS) is a rare, idiopathic inflammatory condition affecting the subglottic airway.
  • Diagnosis requires excluding other causes of stenosis through comprehensive patient evaluation.
  • The condition predominantly affects females and is often limited to the subglottic region and upper trachea.

Purpose of the Study:

  • To analyze the clinical experience with idiopathic subglottic stenosis.
  • To evaluate treatment outcomes for various surgical interventions.
  • To identify factors influencing treatment success and disease progression.

Main Methods:

  • Retrospective analysis of 16 patients diagnosed with ISS.
  • Inclusion criteria: clinical history, laboratory tests, flexible nasolaryngoscopy, and biopsies.

  • Assessment of symptoms, treatments (endoscopic laser, mitomycin-C, laryngotracheal resection), and outcomes.

    • Main Results:

    • 14 out of 16 patients (87.5% female) required surgical intervention for respiratory compromise.
    • Endoscopic laser techniques successfully managed 9 cases; 5 cases failed.
    • Thicker, complex stenoses were associated with endoscopic treatment failure; 2 patients underwent laryngotracheal resection.
    • Mitomycin-C as an adjuvant showed potential benefit.

    Conclusions:

    • Endoscopic laser surgery is a viable first-line treatment for simpler ISS cases.
    • Laryngotracheal resection and reconstruction are indicated for complex or refractory ISS.
    • Adjuvant mitomycin-C may improve outcomes in specific ISS patient groups.
    • Estrogen's role in ISS pathogenesis warrants further investigation.
