Zusammenfassung:We performed a long-term, retrospective, non-controlled study on the functional results of mastoidectomy (both radical and modified radical) and defined the relevant statistical factors that may influence the hearing outcome. In a cohort of 200 patients, we performed both radical and modified radical mastoidectomy (MRM) and followed them clinically for a period of 8.12 years. The functional results were defined by the analytical function of the severity and the period of evolution of the disease. These parameters were defined by assessing the pre-operative absolute hearing threshold (AHT), bone conduction threshold (BCT) and age of the patient at the moment of the operation. The two parameters evolved inversely proportional to the functional results and represented a complete and precise analytical tool. The global average hearing gain ratio was 32% and the ratio for unmodified pre-operative hearing (status quo ante) was 61%. With favorable prognostic factors, the average gain rate was 56% and the hearing-loss rate was 5% (1-dB SPL nominal value). The maximum ratio for gain was 81% and for hearing loss this was 0%.
