Question: A 63 year old male presents to you after noticing progressive, mild hearing loss in his right ear over the last 2 years. He has a distant history of acute otitis media with perforation on the right side 30 years ago and an episode of vestibular neuritis 6 years ago, though he does not recall the side. Examination reveals a 30% R TM perforation. Audiometry reveals a mixed hearing loss on the right side with a sloping mild to moderate sensorineural component, and normal hearing on the contralateral side. Prior to discussing any treatment for his TM perforation, what imaging study would you recommend? [Answer will be posted with next week's new question]
