Videolaryngoscopy (VDL)
Definition: Videolaryngoscopy (VDL) is a diagnostic procedure used to examine the larynx (voice box) and surrounding structures using a flexible or rigid endoscope equipped with a tiny camera and light source. This advanced imaging technology allows for detailed visualization of the larynx on a monitor in real-time, aiding in the diagnosis and treatment planning of various laryngeal conditions.
Purpose
The primary goals of videolaryngoscopy are:
- Evaluate the anatomy and function of the larynx and vocal cords.
- Diagnose disorders affecting the larynx, such as vocal cord lesions, polyps, nodules, cysts, tumors, and inflammation.
- Assess the movement and coordination of the vocal cords during speech and breathing.
- Guide therapeutic interventions, such as biopsies, laser surgery, or vocal cord injections.
Indications
Videolaryngoscopy is typically recommended for individuals who have:
- Persistent hoarseness or voice changes.
- Difficulty breathing or noisy breathing (stridor).
- Chronic cough or throat discomfort.
- Suspected laryngeal cancer or other tumors.
- Abnormal findings on a previous laryngeal examination.
- Evaluation of vocal cord function before and after surgery.
Procedure
Videolaryngoscopy can be performed in an outpatient setting and involves the following steps:
- Preparation: Local anesthetic spray may be used to numb the throat and reduce gag reflex; in some cases, general anesthesia may be used.
- Insertion of the Endoscope: The flexible or rigid endoscope is gently inserted through the mouth and advanced towards the larynx. The camera captures high-resolution images of the laryngeal structures.
- Visualization: Images are transmitted to a monitor, allowing detailed examination of the larynx. The endoscope can be manipulated to view different angles and areas as needed.
- Assessment and Documentation: The ENT specialist evaluates the structure and function of the larynx and may record images or videos for documentation and further analysis.
- Intervention (if needed): Small procedures, such as biopsies, removal of lesions, or targeted treatments, may be performed during the same session.
- Conclusion: The endoscope is carefully removed, and the patient is monitored for immediate post-procedure effects.
Recovery
After videolaryngoscopy:
- Patients can typically resume normal activities immediately.
- Mild throat discomfort or temporary change in voice may occur.
- Discomfort usually resolves quickly, with specific post-procedure instructions provided by the ENT specialist.
Risks and Complications
Videolaryngoscopy is generally safe, but potential risks include:
- Mild throat irritation or discomfort.
- Minimal bleeding at the biopsy site (if a biopsy was performed).
- Rarely, adverse reactions to anesthesia or injury to the laryngeal structures.
Benefits
- Accurate Diagnosis: Provides detailed and magnified views of the larynx, aiding in precise diagnosis of laryngeal conditions.
- Minimally Invasive: Less invasive than traditional laryngeal examinations, reducing discomfort and recovery time.
- Real-Time Imaging: Allows immediate assessment and decision-making during the examination.
- Guidance for Treatment: Supports planning of appropriate interventions based on findings.
