Malleus

The malleus is a hammer-shaped small bone inside the ear, which connects with the incus and is attached to the inner surface of the eardrum.

In 2370, Julian Bashir falsely claimed Quark damaged the malleus in his lobe after fighting T'Kar in order to distract the Klingon mercenary Yeto so Bashir and Quark could free Odo. 

In 2371, Kes was studying medical texts to become a nurse on board the USS Voyager. The Doctor tested Kes on the various parts of the ear, including malleus.
