A eletrocauteriza？？o isolada como adjuvante no tratamento dos tumores ósseos benignos

objectives: to evaluate the efficacy of cauterization as a sole adjuvant method inintralesional resection of benign bone tumors, taking into account associated factors that could influence local recurrence. methods: 47 patients diagnosed with different benign bone tumors were included in this study, all of whom had been treated with curettage associated with cauterization as an adjuvant method. the medium follow-up was 32.7 ± 19.4 months. the recurrence rate was then evaluated in relation to age, sex, location of the tumor, histologic type, tumor grade ( b1, b2 or b3 ), and size and type of material used to fill the tumor cavity ( pmma or autologus bone). the type and percentage of complications were also included in the analysis. results: global recurrence was 19.1%. there was statistic significance relating tumor grade to time to recurrence (p=0,028). no other factors were found that directly correlated with global recurrence of the tumors. conclusion: cauterization proved to be a simple, inexpensive and effective adjuvant method for the treatment of benign bone tumors. level of evidence: level iv, case series.
