Introduction:The main goal of surgery of cholesteatoma is eradication of the disease and revision surgery is indicated when a dry and safe ear has not been achieved. Residual cholesteatoma usually occurs at the sites that are difficult to reach with an operating microscope, such as posterior tympanum and anterior epitympanic recess. Computed tomography can be performed to delineate the extent of disease. High-resolution computed tomography scanning is important for planning for surgery and is indicated for all revision mastoid operations. Magnetic resonance imaging is superior to computed tomography in tissue characterization for diagnosis of recurrent cholesteatoma.Objective: To evaluate the cases of recurrent cholesteatoma comparing the intraoperative surgical findings with the preoperative MRI radiological findings and if the preoperative MRI can replace the second look surgery for cholesteatoma.Patients and methods: This study was applied on 60 patients that have a recurrent cholesteatoma after previous mastoid surgery. A preoperative radiological evaluation was done by Magnetic resonance, surgical management was done by canal wall up or canal wall down mastoidectomy to exclude residual disease. Then, radiological, and surgical findings correlation was done. Results:Diffusion-weighted MRI successfully detected 42 cases out of the 45 cases of surgically proved cholesteatoma, it has accuracy 95%, sensitivity 93.33%, specificity 100%, PPV 100% and NPV 83.33%. Conclusion: MRI is better than CT in tissue characterization for diagnosis of recurrent cholesteatoma, and can replace the unnecessary second look surgery of cholesteatoma
