Name of the Procedure:

Laryngoscopy, indirect with vocal cord injection; also known as Indirect Laryngoscopy with Vocal Cord Injection.

Summary

Indirect laryngoscopy with vocal cord injection is a procedure where a medical professional uses a mirror to view the vocal cords and injects a substance into them to treat various conditions. The technique is less invasive compared to direct laryngoscopy and is performed through the mouth.

Purpose

Medical Condition Addressed:

This procedure addresses conditions like vocal cord paralysis, vocal cord scarring, or other abnormalities affecting the vocal folds.

Goals/Expected Outcomes:

• Restore voice quality
• Improve breathing and swallowing functions
• Reduce symptoms such as hoarseness or vocal fatigue

Indications

• Persistent hoarseness or voice changes
• Difficulty swallowing or breathing due to vocal cord dysfunction
• Diagnostic confirmation of suspected vocal cord issues
• Vocal cord insufficiency

Preparation

• Fasting may be required a few hours prior to the procedure.
• Patients may need to adjust or temporarily discontinue certain medications, as advised by their doctor.
• Pre-procedure diagnostic tests might include imaging studies or voice assessments.

Procedure Description

1. The patient sits in a chair and may be given a local anesthetic spray to numb the throat area.
2. A small mirror attached to a handle is inserted into the back of the mouth to allow the doctor to visualize the vocal cords indirectly.
3. Using a fine needle, the doctor injects the chosen substance (such as a filler or medication) directly into the vocal cords.
4. The mirror is removed, and the patient may be asked to speak or make certain sounds to observe the effects.

Tools/Equipment:

• Handheld mirror
• Fine needle for injection
• Local anesthetic spray

Anesthesia/Sedation:

Typically involves local anesthesia. Sedation is usually not required.

Duration

The procedure typically takes about 20-30 minutes.

Setting

This procedure is generally performed in an outpatient clinic or a doctor's office.

Personnel

• Otolaryngologist (ENT specialist)
• Nurse or medical assistant

Risks and Complications

Common Risks:

• Mild discomfort or gagging during the procedure
• Temporary hoarseness or voice changes

Rare Risks:

• Allergic reaction to the anesthetic or injected substance
• Infection at the injection site
• Bleeding or hematoma formation
• Accidental injury to surrounding structures

Benefits

• Improved voice quality and projection
• Enhanced ability to swallow and breathe more comfortably
• Immediate to short-term relief of symptoms with potential long-term benefits

Recovery

• Patients can usually go home shortly after the procedure.
• Mild throat discomfort or hoarseness may persist for a few days.
• Follow-up appointments are typically scheduled to monitor progress and address any issues.
• Avoid strenuous voice use or heavy lifting for a few days.

Alternatives

• Direct laryngoscopy, which is more invasive and typically requires general anesthesia.
• Conservative treatments such as voice therapy.
• Surgical interventions like thyroplasty.
• Each alternative has its own benefits and risks, and the choice depends on the patient's condition and preferences.

Patient Experience

During the Procedure:

• Patients may feel mild discomfort from the mirror and a slight pinch from the injection.
• Minimal pain due to the local anesthetic.

After the Procedure:

• Some throat discomfort and hoarseness are common but typically resolve quickly.
• Pain management includes over-the-counter pain relievers and soothing throat lozenges.
