In this study, we reviewed the surgical findings in a series of revision tympanomastoidectomy to
determine the most common causes of failure in chronic otitis media surgery.
The intraoperative findings at revision mastoidectomy with tympanoplasty of 116 patients were
analyzed. The most common sites of pathologic tissue at revision surgery (with cholesteatoma
and/ or granulation tissue) were unexenterated cells of the sinodural angle. The most common
mechanical cause of retention of debris in canal wall down procedures was facial ridge.
