Nuances of Pre- and Postoperative Temporal Bone Imaging With Otoradiologists (2023 AMW) Session
2023 AAO-HNSF Annual Meeting & OTO Experience
PROGRAM DESCRIPTION: Imaging of temporal bone is challenging due to the small size of the structures and intricate anatomy, as well as normal variants mimicking pathology. In the pre-operative setting, there are imaging nuances for detecting abnormalities that may influence surgical decision-making and guide the surgeon to the optimal treatment path. The post-operative imaging appearance of the temporal bone can be difficult to interpret due to the wide variety of surgical techniques and materials that may have been used. New imaging tools like photon counting CT have provided better ways to image this area. It is essential for the otoradiologist and the otologist to have a collaborative relationship and understanding of these nuances. This session will be taught by two leading otoradiologists at the forefront of temporal bone imaging, with emphasis on pre- and post-operative appearances of the temporal bone.OUTCOME OBJECTIVE 1: Demonstrate the role of imaging in pre-operative evaluation of the temporal bone, with attention to procedures for treating pathologies such as cholesteatoma, paraganglioma, otosclerosis, superior semicircular canal dehiscence, vestibular schwannoma, and sensorineural hearing loss.OUTCOME OBJECTIVE 2: Illustrate the role of imaging in post-operative evaluation of the temporal bone, with attention to procedures such as tympanomastoidectomy, ossicular reconstruction, stapedotomy with prosthesis, canal dehiscence repair, cochlear implantation, and vestibular schwannoma resection.OUTCOME OBJECTIVE 3: Demonstrate the spectrum of imaging appearances of various materials and hardware used in temporal bone surgery, and the expected post-operative appearance. Provide tips and show pitfalls to enable the otologist to distinguish between expected and unexpected post-operative appearances.BACKGROUND STATEMENT: We are two leading head and neck radiologists with expertise in temporal bone imaging. We believe this would be a good opportunity to provide exquisite imaging examples of expected and unexpected post operative imaging and introduce new imaging techniques like photon counting CT .
