Endoscopic Examination of Larynx

Endoscopic Examination of Larynx

Definition

Endoscopic examination of the larynx is a diagnostic procedure that uses a thin, flexible or rigid scope with a light and camera to visualize the voice box (larynx). It helps detect abnormalities such as inflammation, nodules, polyps, tumors, vocal cord paralysis, or infections.

Purpose of Endoscopic Examination of Larynx

  • To evaluate causes of hoarseness, voice changes, or throat pain

  • To detect growths, swelling, or infections in the larynx

  • To diagnose vocal cord dysfunction, paralysis, or injury

  • To guide treatment planning for ENT and speech disorders

Types and Methods of Examination

Indirect Laryngoscopy

  • Uses a small mirror and light source

  • Quick, simple, and non-invasive

Flexible Fiberoptic Laryngoscopy

  • Performed with a thin flexible tube passed through the nose

  • Provides detailed view of vocal cords and laryngeal movement

Rigid Endoscopy

  • Provides high-resolution images

  • Used to detect structural problems, tumors, or lesions

Stroboscopy

  • Specialized method using strobe light to assess vocal cord vibration

  • Useful in diagnosing subtle voice disorders

Post-Examination Care

  • Temporary mild throat discomfort may occur

  • Voice rest may be advised in some cases

  • Guidance provided for further treatment if abnormalities are found

  • Follow-up scheduled for biopsy or therapy if needed

Benefits of Endoscopic Examination of Larynx

  • Provides clear, real-time visualization of the voice box

  • Detects early signs of cancer, polyps, and other conditions

  • Assists in accurate diagnosis of voice and swallowing disorders

  • Safe, minimally invasive, and effective diagnostic tool
