Petrous bone cholesteatoma is a rare challenging disease that accounts for 4%–9% of all petrous bone lesions. Subtotal petrosectomy with mastoid obliteration without blind sac closure is presented here. A 25-year-old female patient presented with right ear discharge for 5 days, with a history of right ear surgery 19 years back. Right ear external auditory canal showed stenosis suggestive of blind sac closure in the past. High resolution computer tomography and magnetic resonance imaging of temporal bones were suggestive of massive cholesteatoma in right petrous bone with extension into the posterior cranial fossa. As the patient refused blind sac closure, the patient underwent right subtotal petrosectomy, with mastoid obliteration, with wide meatoplasty. The patient is on regular follow-up without any complications. Although blind sac closure is routinely done, mastoid obliteration with wide meatoplasty is an alternative method without increased incidence of complications. Early patient reporting and clinical suspicion of recurrence and prompt treatment is facilitated by wide meatoplasty.
