Laryngoscopy

Why It Is Done

An indirect or direct laryngoscopy helps a doctor:

• Find the cause of voice problems, such as a breathy voice, hoarse voice, weak voice, or no voice.
• Find the cause of throat and ear pain.
• Find the cause for difficulty in swallowing, a feeling of a lump in the throat, or mucus with blood in it.
• Check injuries to the throat, narrowing of the throat (strictures), or blockages in the airway.

Direct rigid laryngoscopy may be used as a surgical procedure to remove foreign objects in the throat, collect tissue samples (biopsy), remove polyps from the vocal cords, or perform laser treatment. Direct rigid laryngoscopy may also be used to help find cancer of the voice box (larynx).
