[Computed tomography of the temporal bones in children with developmental anomalies of the external and middle ear].

Computed polypositional high-resolution tomography (CT) was provided to 45 children with dysplasia of the external acoustic meatus (EAM). The computed tomograms were analyzed in accordance with the scheme which included the evaluation of the following structures: atresia or stenosis area, pneumatized mastoid process, tympanic cavity, ant rum, osteal opening of the Eustachian tube, chain of auditory ossicles, windows of the labyrinth, internal ear, facial nerve canal, and large vessels. Preoperative CT of the temporal bones allows for the evaluation of the above-listed structures, which is of paramount importance for the planning of the patient management policy. Also, CT enables the assessment of the risk of surgical intervention associated with a potential injury to the facial nerve, large vessels, and temporomandibular articulation. CT is to be an indispensable diagnostic modality for examination of children presenting with EAM dysplasia.
