Microlaryngoscopy - Voicebox Surgery

What is a microlaryngoscopy?

Microlaryngoscopy is a minimally invasive procedure that allows your doctor to closely examine your voice box (larynx) while you are asleep under general anaesthetic. It usually takes around 30 minutes. Microlaryngoscopy is commonly performed to diagnose or treat conditions such as hoarseness, vocal cord nodules or polyps, cysts, tumours, or scarring. It can also be used to remove foreign objects or investigate persistent throat symptoms.

Why might you need a microlaryngoscopy?

Your doctor may recommend microlaryngoscopy if you have persistent issues with your voice, throat, or breathing. Common reasons for undergoing this procedure include:

• Hoarseness or voice changes that last longer than three weeks.
• Lumps or growths on the vocal cords, such as nodules, polyps, or tumours.
• Difficulty swallowing or breathing, particularly if it is linked to a problem with your larynx.
• Suspected throat or vocal cord cancer, to take a biopsy or remove abnormal tissue.

Microlaryngoscopy is both a diagnostic and therapeutic procedure, meaning it can help identify the cause of your symptoms and, in many cases, treat the problem during the same operation.

Preparing for microlaryngoscopy

• Let your doctor know if you have neck problems or loose/capped teeth.
• You may be asked not to eat or drink for a few hours before the operation.
• If you take medication, such as blood thinners, you may need to stop these before the procedure.

What happens during the procedure?

• Anaesthetic: You will be given a general anaesthetic, so you’ll be asleep throughout the procedure.
• Laryngoscope: A small metal tube (laryngoscope) is gently passed through your mouth to reach your larynx.
• Examination and treatment: Your doctor will examine your voice box with a microscope. If needed, they may:
• • Take a biopsy.
  • Remove small growths or abnormal tissue.
  • Use special tools, such as a laser or microdebrider, to treat your voice box.
  • No external cuts are made during microlaryngoscopy.
• Duration: The procedure usually takes around 30-60 minutes, depending on the complexity of your condition.

What are the benefits of microlaryngoscopy?

• Clear diagnosis: Your doctor can closely examine the voice box to find the cause of your symptoms, including the ability to detect or rule out cancer.
• Biopsy or treatment: The procedure allows for tissue samples to be taken or treatments to be done during the same operation.
• Minimally invasive: No external cuts or scars.
• Improved voice quality: Particularly if vocal cord nodules or polyps are removed.
• Relief from symptoms: Hoarseness, difficulty swallowing, or breathing problems.
• Quick recovery: The procedure is short, and most people can go home the same day.

Most patients find that microlaryngoscopy helps improve their quality of life by addressing the underlying cause of their symptoms.

What are the potential risks of microlaryngoscopy?

While microlaryngoscopy is generally safe, there are some risks to be aware of:

• Minor damage to teeth, lips, or gums: The metal tube may cause minor cuts or chips to teeth, though protective measures like gum shields are used.
• Bleeding: Spitting a small amount of blood is common and usually stops within 24 hours.
• Swelling: Rarely, swelling in the voice box may cause breathing difficulties. In such cases, you may need to stay overnight for observation.
• General anaesthetic risks: These are rare but may include reactions like a sore throat, nausea, or, very rarely, complications such as blood clots.
• Temporary sore throat, hoarseness, or voice changes after the procedure.
• Bleeding or infection, although these are uncommon.
• Very rarely, permanent voice changes or scarring of the vocal cords.

Your surgeon will discuss these risks with you before the procedure and take steps to minimise them.

What to expect after microlaryngoscopy

Microlaryngoscopy is a safe and effective procedure, with most patients recovering quickly and going home the same day.

• Recovery:
  It’s normal to experience some throat discomfort from the tube used during the procedure. This usually resolves within a day or two and can be managed with pain relief. Temporary hoarseness or weakness in your voice is common, especially if a biopsy was taken. Rest your voice for 24–48 hours by avoiding speaking or whispering. Stay hydrated by drinking plenty of water to soothe your throat and prevent irritation. Avoid smoking, shouting, or straining your voice until fully healed.
• Eating and drinking:
  You can eat and drink the same day. If a throat spray was used, wait until the sensation in your throat returns. Avoid spicy or acidic foods that might irritate your throat during recovery.
• Going home:
  Most people go home the same day once the anaesthetic wears off. If you live alone or have any complications, you may need to stay overnight for observation.
• Results and follow-up:
  Your doctor may provide results on the same day. If a biopsy was taken, it will take a few days to process, and your doctor will contact you to discuss the findings and any further steps.
• Returning to activities:
  Most people can return to work and normal activities within a few days. If your job requires significant speaking, your doctor may recommend additional time off to rest your voice. Follow-up appointments will monitor your recovery and address any concerns.

Microlaryngoscopy is a quick and effective way to diagnose and treat voice box problems. Following your surgeon’s advice and attending follow-up appointments will ensure a smooth recovery.
