TY - CHAP M1 - Book, Section TI - Chapter 64. Osseous Dysplasias of the Temporal Bone A1 - Tsai, Betty S. A1 - Cheung, Steven W. A2 - Lalwani, Anil K. PY - 2012 T2 - CURRENT Diagnosis & Treatment in Otolaryngology—Head & Neck Surgery, 3e AB - Patients with osseous dysplasias of the temporal bone, notably, fibrous dysplasia, Paget's disease, osteopetroses, and osteogenesis imperfecta, present with hearing loss and external auditory canal obstruction that result in infection, lower cranial neuropathies, and temporal bone deformation. Differentiation among these entities is greatly helped by using coronal and axial high-resolution computed tomography (CT) imaging of the temporal bone and skull base. Outer, middle, and inner ear structures are detailed and foraminal stenoses are identified. Bone mineralization density appearance is the single most important imaging feature to secure a diagnosis.
