A 9-year-old boy with a history of recurrent acute otitis media presented to the pediatric otolaryngology clinic for evaluation after failing a hearing screen at school. Of note, he had been using a progressively louder voice over the last several years. Examination of his ears revealed intact tympanic membranes, a small amount of serous fluid in the left middle ear space, and a fully aerated right middle ear space. Audiometric evaluation revealed normal hearing in the right ear and conductive hearing loss in the left ear, with air-bone gaps of 10 and 25 dB at 2 and 4 kHz, respectively. The findings of tympanometry were normal on the right and flat on the left. Computed tomography (CT) of the temporal bone was performed (Figures 1, 2, 3, and 4).
