An endoscope may include a needle and a scope, which may optionally be contained in an elongated shaft. The endoscope may further include a handle comprising at least one button, a visualization component, a reservoir configured to contain a composition, and a dispensing mechanism. The at least one button, the needle, the reservoir, and the dispensing mechanism may be operably linked to cause the composition to be dispensed from the reservoir through the needle to a portion of an ear. A method for using such an endoscope may include inserting the endoscope into a portion of an ear, using the visualization component to visualize the portion of the ear, and pressing the at least one button to dispense the composition from the reservoir through the needle to the portion of the ear.
