Laryngeal Medialisation Injection (LMI) is an injection into one of your vocal cords in order to improve your voice. This is given during mircolaryngoscopy, which is the examination of your larynx (voice box) while you are under general anaesthetic. You will therefore be asleep for the procedure.
Your surgeon has recommended that you have this operation in order to improve the quality and tone of your voice. Microlaryngoscopy gives a very detailed view of the voice box that allows for the LMI to be given.
Before your operation, you will be seen at pre-assessment clinic and will be screened for MRSA with swabs from your throat, nose, armpit or groin. If you have other medical problems, you might also have an appointment arranged for you to see an anaesthetist (the doctor that puts you to sleep for the operation).
Some useful tips.
On the day of your operation, you will arrive on the ward where nursing staff will go through some paperwork with you, check your vital signs (blood pressure etc.) and give you a gown and stockings to wear (to prevent blood clots).
Before your operation, you will see your surgeon who will go through the operation and consent form with you.
You will also see your anaesthetist who will go through how you are put to sleep and answer any questions you may have about this.
The operation involves putting an instrument (laryngoscope) into your mouth to get a good view of the voice box. A microscope is then used to magnify this view.
One of the vocal cords is then injected with a substance to bulk it out and bring it into the midline to allow for the vocal cords to meet. As the operation is done through your mouth you will not have any scars from the procedure.
It is generally quite a short operation and usually takes about 30 minutes. It is likely to be done as a day case, so you should be able to go home the same day.
Microlaryngoscopy is generally a very safe procedure. However, you should be aware of the following risks.
After the first two days of complete voice rest, you may start using the voice gently and sparingly over the next 10 days. After 2 weeks you can use the voice as normal.

The voice box will take 3-4 weeks to fully heal after microlaryngoscopy.
Your surgeon will arrange to see you in the clinic after the procedure. Here, you will discuss the results of the surgery as well as any necessary further treatment options.
