Laryngoscopy is a medical procedure used to examine the larynx (voice box) and surrounding structures. Doctors commonly use it to diagnose throat problems, voice disorders, and breathing issues.
In addition, this procedure helps detect conditions such as infections, tumors, and vocal cord abnormalities. Because of its importance, laryngoscopy plays a key role in ENT (Ear, Nose, and Throat) care.
What is Laryngoscopy?
Laryngoscopy is a diagnostic and sometimes therapeutic procedure. It allows doctors to view the throat using a special instrument called a laryngoscope.

2. Direct Laryngoscopy
In this method, a rigid or flexible scope is inserted into the throat.

3. Fiberoptic (Flexible) Laryngoscopy
This is the most commonly used modern technique.
