Objective: to evaluate the status of an osteograft after mastoidoplasty according to temporal bone histological examination and computed tomography (CT). Subjects and methods. Ninety-six patients diagnosed with chronic epitympanic antral suppurative otitis media were operated on. Coarse bone meal was used in 51 (53%) cases; finely dispersed meal was employed in 45 (47%) cases. CT of the temporal bones and histological examination of the graft were performed in the patients at 12 months after surgery. Results. Analysis of temporal bone CT data showed that the implanted bone graft was less dense than the cortical plate of the mastoid process. Nineteen implanted bone graft samples were histologically examined at 12 months after surgery. Mature bone beams of correct structure were detected in 9 (47.4%) samples. Young bone tissue elements as osteoid and uneven young osteogenic tissue growths were prevalent in 10 (52.6%) cases where finely dispersed bone meal had been used. Conclusion. Temporal bone CT allows evaluation of the status of the implanted bone material in the long-term postoperative period. The histological examination at one year after surgery indicated that when coarse bone meal versus finely dispersed one was used, the bone material underwent all stages of integration mainly through osseointegration.
