study of 153 discharging ears of 148 patients in Basrah General Hospital during 2
years period. This study showed that most commonly affected age group was below 10 years (44
patients=30%), the most common type of otorrhea was the purulent (127 ears=86%), the most
common cause of purulent otorrhea was chronic otitis media (77 ears=61% of purulent discharging
