Microlaryngoscopy is a procedure that means the vocal cords are looked at in great detail using an operating microscope. It is often accompanied by some additional procedure such as removal of a nodule, mass, swelling or tumor. It is performed in the operating room under General anesthesia.
Voice problems, such as a hoarse voice, weak voice or no voice
Removing foreign objects
Taking a biopsy, which is a small tissue sample
Removing polyps from the vocal cords
Performing laser treatment, which uses a tiny intense, focused beam of light to cut tissue.
When Microlaryngoscopy is performed in the operating room, it is usually done with the patient asleep (general anesthesia).
With the head tilted back (to make the airway as straight as possible), a laryngoscope is placed in the mouth to look at the larynx (voice box). It also pushes the tongue out of the way. If the patient is old enough to have upper teeth, they are protected with a tooth guard. The involved area is then visualized and the view is magnified using operating microscope. This is usually attached to a small video camera.
Procedures that may be performed during Microlaryngoscopy are numerous, and include removal of polyps or masses on or around the vocal cords or to correct deformities of the vocal cords themselves. These procedures involve the use of special tools and techniques, and may include use of the CO2 laser. The procedure usually does not last more than an hour.
If the patient has a history of neck problems or chipped or loose tooth, they should inform the surgeon and anesthetist about this before your operation.
After surgery patient is kept in post operative ward for few hours for observation and discharged home the next day. You may be advised to stay off work for a few days to rest your throat, depending on your job.
However, if the surgeon has taken a biopsy from your voice box, he may advise you to rest your voice for a short period.
