[High-resolution computed tomography in the diagnosis of branchial otodysplasias. A report on 10 cases (15 ears)]. / La tomografia computerizzata ad alta risoluzione nella diagnostica delle otodisplasie branchiali. Rapporto su 10 casi (15 orecchi).

Computed Tomography (CT) is not yet widely employed in the evaluation of temporal bone diseases in pediatric patients. Our experience is reported in the study of branchial otodysplasias (10 cases, 15 ears) by means of a high-resolution program. Indications, advantages, limitations and risks of this technique are discussed. Some technical details are reported, such as number and type of scans, length of data acquisition, thickness and feed of slices, electronic image reconstruction, and radiation doses given to the lens. The method employed to immobilize younger patients is also described. CT findings in the single cases are summarized in the tables. The most significant images of 5 cases are also reproduced. A careful analysis of the cases in our series highlights the advantages provided by the use of high-resolution CT in the evaluation of the temporal bone in pediatric patients, especially as far as dysplasias are concerned.
