We report two cases of ossicular lesions correctly diagnosed with three-dimensional CT (3D-CT). The first patient was a 28-year-old male, who had hearing loss in the right ear after a sneeze. The other patient was a 50-year-old male complaining of left ear hearing loss after a head injury. Almost normal hearing was obtained after tympanoplasty type IV-c (case 1) and partial stapedectomy (case 2). Both patients underwent operations by transcanal approach.
We were able to make exact diagnoses before operation by 3D-CT in both cases, and 3D-CT reconstruction of the operation field was suitable for modeling of the operations. These cases suggest that 3D-CT is useful not only as a method for diagnosing ossicular lesions, but also as a method for preoperative surgical planning.
