Usefulness of high resolution CT scanning before and after tympanoplasty

The usefulness of high resolution CT scanning in pre- and postoperative examinations was evaluated in 135 ears treated with tympanoplasty. The CT findings were correlated with operative findings and postoperative results. Preoperative CT scanning can demonstrate the presence and extent of pathological changes in the middle ear space, the status of the ossicular chain (especially the incudo-stapedial joint), the presence of labyrinthine fistulae, etc. The condition of the reconstructed tympanic membrane, the ossicular chain and the aerated space in the tympanic cavity can be clearly observed on CT scanning during the postoperative period.
