1. Diagnosis:
Visualizing the larynx and vocal cords:
Fiber-optic laryngoscopes allow doctors to directly examine the larynx, vocal cords, and surrounding structures.
Identifying airway abnormalities:
This helps in diagnosing conditions like laryngomalacia (softening of the voice box), vocal cord paralysis, subglottic stenosis (narrowing of the airway below the vocal cords), and other structural issues.
Assessing airway dimensions:
It helps determine the size and suitability of the airway for procedures like intubation or surgery.
2. Guiding procedures:
Intubation: Fiber-optic laryngoscopes can be used to guide the placement of breathing tubes (endotracheal tubes) in children, especially in cases where direct laryngoscopy is difficult or contraindicated.
Foreign body removal: The scope can help locate and remove foreign objects lodged in the airway.
Biopsy: It allows for the collection of tissue samples (biopsies) for further analysis.
