However, the pain persisted for a full day, so her parents have taken her to her pediatrician. Her parents have noticed that she is less responsive when speaking to her from her right side and are worried that she has suffered hearing loss from the fall.

Maddie’s physician explains that there are different types of hearing loss. Damage to which of the following structures would causeconductive hearing loss?
