Peroperative findings in 145 consecutive cases of chronic suppurative otitis media, operated at Civil Hospital, Karachi were recorded. The mean age was 24 years. More than half of the patients (51%) had subtotal perforations and majority had damage of more than one ossicle. Involvement of all the three ossicles was seen in 30 (40%) cases. The frequency of damaged malleus along with incus was higher than other series. Granulations and subtotal perforations were commoner and could account for it. Extensive cholesteatoma was present in 30 cases.
