Congenital glottic web of larynx

Last edited: 4/15/2026

Overview

Congenital glottic web of the larynx is a rare congenital anomaly characterized by a fibrous or membranous band that partially or completely divides the vocal cords, leading to significant voice impairment and airway obstruction 2.

Diagnosis

  • Clinical Presentation: Characteristic voice quality abnormalities, often including breathiness and reduced phonatory efficiency 2.
  • Diagnostic Tests:
  • - Laryngovideostroboscopy: Essential for visualizing the web and assessing glottic closure 2. - Acoustic Analysis: Useful for quantifying voice parameters such as jitter, shimmer, and fundamental frequency 1. - Videolaryngostroboscopy: Provides detailed visualization of vocal fold dynamics and abnormalities 2.

    Management

  • Surgical Intervention: Primary treatment often involves endoscopic web excision or laser division to restore vocal fold mobility and voice quality 2.
  • Postoperative Assessment: Regular follow-up with laryngovideostroboscopy and acoustic analysis to monitor voice recovery and detect complications 2.
  • Voice Therapy: May be beneficial post-surgery to optimize vocal function and rehabilitate voice quality 3.
  • Special Populations

  • Elderly: Limited data; management focuses on minimizing surgical risks and optimizing postoperative rehabilitation 3.
  • Comorbidities: Underlying conditions affecting the glottis (e.g., masses, neuromuscular disorders) require concurrent management to improve outcomes 2.
  • Key Recommendations

  • Primary Surgical Intervention for Congenital Glottic Web: Endoscopic web excision or laser division is recommended to restore vocal fold function (Evidence: Moderate 2).
  • Comprehensive Postoperative Evaluation: Regular use of laryngovideostroboscopy and acoustic analysis to monitor recovery and address any residual issues (Evidence: Moderate 2).
  • Consider Voice Therapy Post-Surgery: To enhance vocal rehabilitation and quality, especially in assessing long-term outcomes (Evidence: Expert opinion 3).
