Treatment Alternatives

Preoperative Instructions

Microlaryngoscopy is performed under a general anaesthetic. You will need to fast prior to surgery and should follow the provided instructions. If you have any queries or concerns please contact your Anaesthetist, admitting hospital or Dr Morrissey.


Once the patient is asleep, Dr Morrissey will fashion a mouth guard to protect the teeth, lips and gum. He then places an instrument called a laryngoscope into the throat to allow visualization of the airways. A camera or microscope may be used to improve the view. Specialised instruments can then be used as needed to address the particular concern in each case.

At the conclusion of the procedure, Dr Morrissey will check that any bleeding is controlled and remove the instruments.

Postoperative Instructions
