Canal wall-up timpanoplasty is increasing its popularity as the preferred treatment for cholesteatoma. Nevertheless, the significant recurrence rate of this disease turns the choice for surgical treatment controversial and difficult. Aiming to analyze tympanomastoidectomy success rate in Hospital São José’s Otolaryngology Department, to establish eventual predictive factors for failure and to evaluate the computed tomography scan’s value in the study of this pathology, we present a retrospective study since 2005 to 2009. Some factors were identified as related to failure, such as the presence of cholesteatoma in the sinus tympani, the scutum erosion and the large extension of initial disease. The computed tomography scan presented a limited value in the diagnosis and evaluation of the disease, especially in post-operative patients. In the absence of more accurate diagnostic procedures, we recommend the second look surgery as the most precise instrument in controlling cholesteatoma’s recurrence.
