Voice or breathing problems

HCA UK uses a small microscope to study your voicebox to identify potential causes of voice or breathing problems


While under general anaesthetic your consultant will study your voice box, known as the larynx, with a small microscope. This means you'll be asleep when the procedure is performed. Your consultant will be able to diagnose and treat any problems of the larynx that may be affecting your voice or your breathing.

Need to know

  • What happens icon plus

    Your consultant will explain the procedure to you in detail and answer any questions that you might have. Your anaesthetist will explain how the anaesthetic works. If you have any existing medical problems, such as allergies, please tell your consultant. About half an hour before the procedure you may have a pre-medication. This is a special medication which dries up any secretions, allowing your consultant to see your airway more clearly. It may be given as an injection or as a liquid medicine to drink. The actual procedure should take around 30 minutes.
  • How to prepare icon plus

    Your consultant will tell you how you should prepare, but you may want to avoid things that irritate the voice box e.g. smoking, alcohol, or caffeine. You should also avoid eating or drinking in the hours before your anaesthetic.
  • Afterwards icon plus

    You'll probably be required to stay overnight in the hospital following the procedure. You may have a sore throat and be prescribed some paracetamol to help manage this. You'll also not be able to eat or drink anything for three hours after the procedure. Your consultant will see you later the same day to tell you what they found during the investigation.
