We acted a long-term, backward-looking, non-controlled study on the anatomic (seepage), functional (trial) and reconstructive (ossiculoplasties) results of both radical and modified radical mastoidectomies. For ossicular chain rebuilding we used bioceramic implants of earliest origin and defined the mathematical relevant determinants that could influence the rate of insert rejection. In a cohort of 200 cases with mastoidectomies, we acted ossiculoplasies with bioceramic implants on 108 patients and attended them clinically for a ending of minimum 7 years. We have defined various factors that take care of influence the results of the implantation and intentional the statistic correlations. The denial rate after 9.12 age was 21% (23 patients). Histological integration rate was 79% (85 sufferers), similar to results stated in literature for both bioceramic and titanium implants. Hydroxyapatite has many of the ideal traits required expected a good prosthesis accompanying a high degree of biocompatibility, very low banishing rate, low risk of affliction transmission and good functional results. Although possibly considered of classical interest, bioceramic implants are cheaper and can be caused locally, that is a great benefit for struggling economies.On the alike inital cohort of 200 cases we defined the functional results by analitical function of the asperity and the period of progress of disease. These criteria maybe defined by determining the patient's pre-operative categorical hearing thresholds (AHT), bone broadcast threshold (BCT), and age event of surgery. The two parameters progress inversely equivalent to the functional results, resulting in a inclusive and exact analytical form. The global average learn gain ratio was 32% and the ratio for straight pre-operative trial (statu-quo ante) was 61%. With favorable prognostic determinants the average gain rate was 56% and the hearing-misfortune rate was 5% (1- dB SPL nominal value). The maximum ratio for gain was 81% and for trial loss was 0%.The drainge (fundamental) results, similar to earlier published functional results, are delimited by analitical function of the severity and the ending of evolution of disease. Our main aim was to delimit the situations and factors (attendance of complications, type of ailment, type of tympanic perforation or rank of ossicular chain) that influence the drainage results and could present us some somewhat anatomical prognosis. The effect started at the present of complete epithelization for each cavity as period represents the main study corresponding criteria. Drainage failure was evaluated by the number of otorrhea adventures. We conclude that nearly and ideally, we can clean out a maximum of 84% of the mastoid and rugged cells. Our results of 78% draninage happiness are congruent to this theory. The staying 16% of cells can contain irreversible lesions.
