Abstract | The study involves 52 revision operations within surgical treatment of otosclerosis, which were performed consecutively over a period of 10 years (between 1992 and 2001). A retrospective review of these cases reveals that the most common reasons for revision surgery were prosthesis displacement out of the oval window and/or from the tip of the incus, proliferation of fibrous tissue over the oval window, otosclerotic bony regrowth and necrosis of the distal portions of long process of the incus. The postoperative results were reported as an air-bone gap. This was defined as a difference in dB between postoperative air conduction pure-tone average minus preoperative bone pure-tone average at speech frequencies. Our postoperative results showed that closure of the air-bone gap to less than 10 dB was achieved in 25 cases (48.1%). The surgical findings and results are comparable with other reported series. | |
Summary | V desetih letih (1992 do 2001) smo pri kirurškem zdravljenju otoskleroze opravili 52 reoperacij. Te primere smo retrospektivno analizirali in ugotovili, da so bil najpogostejši vzroki za ponovno operacijo: zmaknjena proteza iz ovalnega okenca in/ali kraka nakovalca, razrast fibroznega tkiva preko ovalnega okenca, ponovna razrast otosklerotičnega žarišča v okencu in nekroza distalnega dela dolgega kraka nakovalca. Pooperacijski rezultat smo izrazili z zračno-kostno vrzeljo. To smo določili tako, da smo izračunali razliko v dB v tonskem pražnem avdiogramu med pragom sluha po zračni in kostni poti v govornih frekvencah. Naši pooperacijski rezultati so pokazali, da smo v 25 primerih (48,1%) dosegli zaprtost med zračno in kostno krivuljo v povprečju 10dB ali manj. Naše operacijske ugotovitve in rezultati so primerljivi s poročili drugih avtorjev. | |
