Myringotomy knife
A very small, sharp blade, straight or angled, mounted on a fine handle, designed to make a controlled, precise incision in the tympanic membrane.
How it is used
Used to perform myringotomy, an incision in the eardrum to drain middle ear fluid and, often, subsequently insert a ventilation tube.
Clinical tip
The incision is typically made in the anteroinferior quadrant of the eardrum to avoid injuring the posterior ossicular chain.
