Categories of laryngoscopies
There are two main Categories of laryngoscopies:
·Direct laryngoscopy: Involves using a rigid laryngoscope inserted through the mouth to visualize the larynx.
·Flexible laryngoscopy: Uses a flexible fberoptic scope inserted through the nose to examine the throat and larynx.
Different types of laryngoscopes
·Paediatric laryngoscope:Tailored for paediatric patients, these laryngoscopes feature smaller blade sizes and handles to suit children's anatomies.
·Video laryngoscope: Offering a clear view of the airway anatomy, these laryngoscopes facilitate easier intubation, particularly in challenging airway scenarios.
Fibre optic laryngoscope: Utilising flexible fibre-optic bundles, these laryngoscopes transmit light to the blade tip for visualisation purposes.
Features of laryngoscope
Below are several common attributes observed in laryngoscopes:
1. Illumination system: Laryngoscopes are equipped with an inbuilt light source to illuminate the larynx and vocal cords, enhancing visualisation.
2.Video capabilities:Certain laryngoscopes integrate a camera within the blade, facilitating video-assisted laryngoscopy.
3.Anti-fog mechanism: To prevent blade fogging during usage, select laryngoscopes incorporate anti-fogging technology.
4.Ergonomic structure: Many laryngoscopes are engineered with ergonomic features, including comfortable handles and well-balanced weight distribution.
5. Portability: Some laryngoscopes are designed to be compact and easily transportable, catering to diverse usage scenarios.
Uses and indications of flexible laryngoscopy
Flexible laryngoscopy is commonly used for:
·Diagnosing vocal cord disorders.
·Evaluating voice changes or hoarseness.
·Assessing swallowing difficulties.
·Monitoring treatment progress for throat conditions.
