Cone beam computed tomography in the ENT area as routine tool

Introduction The cone beam computed tomography (CB-CT), in German called „digitale Volumen Tomografie (DVT)“ is a special X-ray technique which is established in the fileds of ENT surgery, dentistry and implantology. The low dose technique offers a reduced radiation exposure generating three dimensional pictures.

Investigation We present a prospective studdy on 176 patients ( 50.5. male, 49.5 female, average age 48.3.y) with CB-Ct of the temporal bone (39.8%) and the paranasal sinuses (60.2%). mainly for chronic middel ear disease and acute or chronic sinusitis. Also the eletrode position after CI-surgery was proved postoperatively in 14 cases.

ConclusionN The bony structures of the scull, the midface and the temporal bone are visualized exactly showing the anatomy as well as pathological findings in the mastoid, the middle ear and the paranasal sinuses. In addition, CB-CT (DVT) may serve as a quality control tool focusing on the evaluation of cochlear implant position. The range of applications, indications and current examples of CB-CT (DVT) results are illustrated exspecting a broader use of this evaluation technique in the future.
