Background and Objectives: Chronic otitis media causes many complications and disability in hearing system that requires surgery. The efficacy of tympanomastoidectomy procedures for chronic otitis media (COM) on controlling infection was assessed in four hundred patients by means of four- point rating scale that incorporated both symptoms and signs, such as the presence or absence of otorrhea and granulation tissue.
Materials and Methods: This study was retrospective review of the 400 procedures. Of these, 210 were performed for COM with cholesteatoma and 190 for active COM with granulation tissue but no cholesteatoma.
Results: Of the four hundred surgical procedures performed , ninety percent were primary procedures , and 10% were revisions and patients were followed-up for 12 months. Infections were controlled in 364(91%) of these 400 cases. Of the 26 cases (9%) that developed persistent infections, 16 were controlled with a combination of oral and topical antibiotics. Thus, overall satisfactory control of infection was achieved in 390 of 400 cases.
Conclusion: Although, outcome of surgery was influenced by the diagnostic category of COM and COM with granulation tissue, it was not influenced by the following variables : primary versus revision surgery , canal wall- up versus canal wall- down surgery, and extent of disease .
