We observed that perspective 3D-volume rendering of the cochlea enables the determination of key features of cochlear morphology and orientation that may escape detection with routine computed tomographic scanning. Infants and young toddler candidates demonstrate greater variability in the dimensions of the cochlear base and in the orientation of the cochlea within the cranium. As evolving surgical techniques and device design enhance the ability of the surgeon to avoid cochlear damage and optimize electrode location, refined morphometric information may assist the surgeon in tailoring strategies of scala tympani implantation.
Osteonecrosis of the mandible and maxilla occurs as a complication of bisphosphonate treatment of bone metastasis and osteoporosis and typically manifests after a dental procedure. Magnetic resonance imaging and bone scintigraphy findings may precede clinical symptoms and mimic metastatic disease.
BACKGROUND AND PURPOSE:Sclerosis of the arytenoid cartilage may be seen as an incidental finding in patients who do not have laryngeal cancer but may also be an early sign of neoplastic infiltration. Our purpose was to determine the frequency of asymmetric mineralization, in particular sclerosis, of the arytenoid cartilages on CT scans in adults who have no history of laryngeal cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
