    • Abstract:
      Temporal bone CT was used to examine a group of 87 patients with chronic purulent otitis media (103 temporal bones). The patients' age ranged from 2 to 74 years. A scheme was developed and proposed to evaluate the temporal bone by CT. The CT signs of chronic purulent otitis media uncomplicated by cholesteatoma and those of cholesteatomic purulent otitis were identified. The CT symptomatology of chronic purulent otitis includes: sclerotic changes in the bone tissue of the mastoid process, impaired pneumatization of the cavities of the middle ear, including the tympanic cavity, destructive changes in auditory ossicles, carious changes in the walls of the cavities of the middle ear. The CT semiotics of cholesteatoma depends on its site and spread into the temporal bone and includes as follows: deformation of the epitympanum due to soft tissue mass-induced destruction of the lateral wall; the dilated entrance into the antrum; the presence of a cavity with the sclerosed walls in the antromastoid area; carious changes in the auditory ossicles; the displacement of a chain of ossicles medially or laterally in relation to the initial site of cholesteatoma. CT reflects carious changes in the walls of the cavities of the middle ear, including the roof and labyrinthine wall of the tympanum, which allows labyrinthine fistula and intracranial cholesteatomic complications. The study of the temporal bone by the proposed scheme may reveal anomalies and the specific features of its structure: the presentation of the sigmoid sinus, the high elevation of the bulb of the jugular vein, diverticulum of the latter, the low standing of the bottom of the ACH.
