Examination of Throat/Voicebox Under Anaesthetic

What is micro laryngoscopy?

A laryngoscopy or microlaryngoscopy involves a close look at your voice box (larynx or vocal cords).

Procedure and anaesthetic

While you’re being put under general anaesthesia and asleep, the surgeon will insert a metal tube, known as a laryngoscope, through your mouth into your larynx (voice box). A camera, functioning as a microscope, will then be used to examine the larynx.

This allows the ENT (ear, nose, and throat) specialist to examine the reasons behind your vocal issues, such as hoarseness. If necessary, the doctor might remove any abnormal growths or a portion of the voice box lining for further analysis in a lab (biopsy).

Based on the nature of the growth a laser may occasionally be employed for its elimination. Microlaryngoscopy is a brief procedure and typically concludes in under 30 minutes. While under general anaesthesia, the anaesthesiologist will, utilizing the anaesthetic medication, maintain you in a state of deep sleep.

Risks and complications

You might feel a mild discomfort in your throat. However, there’s a very minimal chance of damaging a tooth because of the metal tube. A bruise on the vocal cords could lead to a short-term change in the sound of your voice. Bleeding and infection could also happen during the surgery or in the days following it.

What happens after the procedure?

The procedure is often carried out either as a day procedure or a one-night hospital stay. In either scenario, you will only be discharged from the hospital once you are feeling sufficiently recovered.

Time off work

At least one week off work/school.

Follow- up

f you had any tissue samples removed, they usually need a few days to analyse in a research lab. Your doctor will plan to revisit you to discuss the outcomes, which usually occurs between 2 to 6 weeks following the procedure.

Post-operative care & advice

Do I need to stop talking? If you have had a biopsy or surgery to the voice box, do not use your voice at all for two days.

Utilise pen and paper or hand signals to convey messages. Following that, employ a soft-spoken tone for a week, meaning speaking quietly and sparingly only when needed.

In a case of a microlaryngoscopy (where the physicians only looked at the throat and vocal cords), you don’t need to completely rest your voice. Speak softly and sparingly for the initial five days.

What can I do to conserve my voice?

  • Steer clear of raising your voice, competing with ambient sounds, singing, speaking softly, and vocalising from one space to another.
  • Should your vocal cords feel sore from speaking, give your voice a break of at least half an hour. Don't force your voice into conversation, even if it results in speaking in a hushed or weak manner.
  • Make an effort to consume water often throughout the day (except as directed by your physician).
  • Cut down on drinking alcohol and consumption of caffeinated beverages (tea, coffee, cola).
  • Steer clear of smoky, arid, or dusty environments.
  • Spicy, hot, and sour food/drinks can lead to discomfort in the throat.
  • Breathing in steam can help if you have mucus or congestion.
  • Strong throat clearing and coughing can harm the vocal cords. Take a small sip of water with your chin tucked in - if you still need to clear your throat, do it softly.
  • You might be sent to Speech and Language Therapy to meet a specialist in vocal issues. This person will evaluate you, provide guidance, and recommend exercises for voice recovery as necessary.
