Rigid and Flexible Laryngoscopy: An Overview

Introduction

Laryngoscopy is a critical diagnostic and therapeutic procedure used in otorhinolaryngology to visualize the larynx and vocal cords. Two main types of laryngoscopy exist: rigid and flexible.

Flexible Laryngoscopy: Procedure and Equipment

Overview

Flexible laryngoscopy is a minimally invasive technique that allows direct visualization of the larynx, pharynx, and vocal cords.

Procedure

• The patient is typically seated in an upright position.
• A topical anesthetic is applied to the nasal passages and throat.
• A flexible fiberoptic laryngoscope is gently inserted through the nasal cavity.
• The physician assesses the anatomy and function of the larynx.
• Findings are recorded, and if necessary, biopsies or therapeutic interventions are performed.

Equipment

• Flexible Fiberoptic Laryngoscope: A thin, flexible tube equipped with a camera and light source.
• Topical Anesthetic: Lidocaine spray for patient comfort.
• Video Recording System: Enables documentation and further analysis.

Clinical Applications

Flexible laryngoscopy is commonly used for diagnosing vocal cord dysfunction, laryngeal cancer, and airway obstruction.

Advantages

• Minimally invasive.
• Can be performed in an outpatient setting.
• Provides real-time visualization of vocal cord function.

Conclusion

Flexible laryngoscopy is an indispensable tool in ENT practice, offering diagnostic precision and therapeutic utility.
