Answer 33

Inflammation of the inner ear that usually results from an acute viral disease, such as mumps, measles, or influenza

Answer 34

Increased fluid pressure of the endolymphatic system that leads to progressive loss of hearing; also called endolymphatic/labyrinthine hydrops

Answer 35

Condition caused by the destruction of hair cells, the organs responsible for hearing, as a result of sounds that are “too long, too loud, or too close
