Maria, a 9-year-old girl, told the clinic physician that her “ear lump hurt” and she kept “getting dizzy and falling down.” As she told her story, she pointed to her mastoid process. An otoscopic examination of the external acoustic meatus revealed a red, swollen eardrum, and her throat was inflamed. Her condition was described as mastoiditis with secondary labyrinthitis (inflammation of the labyrinth). Describe the most likely route of infection and the infected structures in Maria’s case. Also explain the cause of her dizziness and falling.
