Laryngoscopy
Category: Endoscopy & Camera Tests · All endoscopy & camera tests
What it is
Laryngoscopy examines the voice box (larynx) and vocal cords. In clinic this is often done with a flexible scope through the nose; in theatre, under general anaesthetic, a rigid instrument gives a close view and allows biopsies and small procedures.
Why it is done
It is used to investigate persistent hoarseness, voice change, throat symptoms and suspected growths, and to take samples or remove small lesions.
How to prepare
Clinic laryngoscopy needs no preparation. For theatre laryngoscopy you will fast, have a pre-assessment and review of medicines.
What happens during the procedure
In clinic, the flexible scope is passed through the numbed nose and you make sounds while the cords are watched. In theatre you are asleep while the surgeon examines with a microscope or rigid scope and takes samples if needed; this usually takes 15 to 30 minutes.
Afterwards — recovery & results
Clinic patients go straight back to normal activities. After theatre laryngoscopy a sore throat and hoarse voice for a few days are common, and you may be advised to rest the voice. Biopsy results usually take one to two weeks.
Risks & considerations
Clinic examination is low risk with brief discomfort and occasional nosebleed. Theatre procedures carry anaesthetic risks and a small risk of dental or lip injury from the instrument, which the team protects against.

Frequently asked questions
Why does hoarseness need a scope?
Hoarseness lasting more than a few weeks needs the cords to be seen directly, because causes range from simple inflammation to early growths that are very treatable when found early.
Will I need to rest my voice after theatre laryngoscopy?
Usually for a few days if samples were taken or a lesion removed. Your surgeon will tell you how long, as it aids healing.
